1. Battle Born LiFePO4 Deep Cycle Battery - 100Ah 12v with Built-in BMS - 3000-5000 Deep Cycle Rechargeable Battery - Perfect for RV/Camper, Marine, Overland/Van, and Off Grid Applications

    Features:
  • BUILT-IN BMS: BMS stands for "Battery Management System" - the brain of our deep cycle lithium batteries. Our BMS protects your battery from most common causes of battery failure, such as temperature volatility or ground faults. The BMS regulates the amount of power taken out of the battery and acts as a shut-off system to protect the li-ion cells (and you) from unsafe operating conditions.
  • LITHIUM ION TECHNOLOGY: Unlike Lead Acid batteries, Battle Born's deep cycle lithium ion batteries have unlimited mounting capability, exceptional longevity, and are more cost effective. When factoring time and cost into your purchase, our lithium ion battery banks come out ahead every time. Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults.
  • GREEN ENERGY BATTERIES: Made from 100% safe, nontoxic, renewable energy, Battle Born Batteries last for more cycles and can be charged and discharged repeatedly (and charge faster than any other battery). We make our renewable, sustainable green energy batteries because they’re simply better than anything else out there, including other green batteries.
  • LIGHTWEIGHT AND VERSATILE: At a sleek 31 lbs, our 100Ah 12v battery weighs in at only 1/3 the weight of lead acid batteries! With no acid in the battery, you're able to safely mount in any position. This makes li-ion batteries perfect for marine, RV, campers, golf cart, off-road and off-grid applications!
  • *Please note, orders of six or more batteries will ship via freight and will require you to be able to accept a pallet shipment.

u/pyromaster114 · 1 pointr/SolarDIY

Here's a 'shopping list' for as light-weight a system that I can think of throwing together from 'off the shelf' components:

>Solar Panels:
Two of these will give you a light-weight solution for 400 watts of power!
https://www.amazon.com/Dokio-Monocrystalline-foldable-Inverter-Controller/dp/B075SZMFP2/

>Charge Controller:
The included controller won't be terribly useful I'm afraid, because it's for Lead Acid, and is a crappy PWM controller anyways. So, let's assume you're going to DIY this a bit and build a weatherproof box for your battery and a controller like this one:
https://www.amazon.com/Solar-Controller-Monitor-Temp-Sensor-Package/dp/B06XNP1BGR/

>Batteries:
Here's where you drop the real cash; At least one but preferably TWO of these guys.
https://www.amazon.com/LiFePO4-volt-Deep-Cycle-Battery/dp/B06XX197GJ/

>Inverter:
If you'll be needing AC power, you'll want something like this:
www.amazon.com/AIMS-Power-Watt-Inverter-Cables/dp/B002AMPHHC/

>Container of sorts:
You'll be needing something weatherproof for all this non-weatherproof stuff to sit inside. Find the 'weatherproof storage lockers' at sporting goods stores, and you can machine them to be what you need for stuff like this. It'll need to fit your batteries, inverter, and charge controller, and you'll need to mount them in there somehow so it doesn't bounce around. Then all you need is some slick weatherproof electrical connectors to mount going through the wall of the box, and you've got yourself a great system. You can even put in things like a 12 socket and weatherproof volt meter to keep an eye on your battery voltage.

Overall, this would cost probably around $3000. But, it'd work well. :)

If you can give me more specs on what sort of weight you can carry, you could have the option of switching to Lead Acid as a battery type; but that would add like 150 pounds of weight to this whole setup, but you'd save $1500 or there about on the batteries, and you COULD use the included cheap PWM controllers... but honestly that MPPT I think would be worth the extra cash.

The comparable product (excluding the panels, and assuming you only got one battery) would be the Goal Zero Yeti 1400 Lithium. It's $1700 and is about the same thing, again excluding the panels.

Honestly, for your purposes, the Goal Zero Yeti looks pretty good if you're not really into the DIY stuff; cause you'd be looking at $1700 plus $500 for the 400 watts of panels, so $2200 total. That's not bad! (Assuming you DIY it like I'm suggesting, and only use one battery, you're looking at around $2000. So, really, not much cheaper if the weight matters to you.)

u/optifrog · 1 pointr/vandwellers

The yeti is nice, i have never used one. Some say it is overpriced, but you have to admit that it is a nice simple all in one thing - battery, usb,300 watt pure sine wave inverter, and can charge from 120 vac,12vdc,or solar.

It is what it is, 33Ah battery so if that is not enough then what? If you are going to charge from 12 (like your car) you will need hours and hours. Now if you are willing to put an isolator on you van/car? you could charge faster than a cigarette lighter socket but then you are adding complexity for just using occasionally. So if you can live with the capacity then it's a neat package.

The prices for the big yeti are over $1.4K ? I think that is 100Ah of battery. I think that would get you through a weekend with enough spare energy as to not have to ration. idk And this would just be charged at home or if you find 120vac while you are away.

I will think it over more as it is late for me. But what I have done before is to use a battery box and a separate inverter. The box and battery(battery is bad now) I owned from the trolling motor set up for my canoe. It is not a clean set up but can be used in pieces as you like. So if you have separate pieces and your battery runs low you just hook up the inverter to the van, and don't run out of fun times.

here are some amazon links - non referrals so take a look and seeif you get what I mean.

https://www.amazon.com/MinnKota-Trolling-Motor-Power-Center/dp/B001PTHKMG Nice thing here is it will hold any battery up to group 24 or 27

https://www.amazon.com/VMAXMB127-Battery-Replacement-Caddy-Golf/dp/B00BDV7OO0 I just picked a 100Ah battery at random

https://www.amazon.com/Wagan-EL2601-Elite-400W-Inverter/dp/B007Y4BL1C

https://www.amazon.com/VMAXTANKS-Maintainer-Automobile-Batteries-maintain/dp/B00IZV91Q0/ref=pd_sim_263_3?_encoding=UTF8&pd_rd_i=B00IZV91Q0&pd_rd_r=2VBEJM4WJG5N3CAX8905&pd_rd_w=uLdL1&pd_rd_wg=0Vigf&psc=1&refRID=2VBEJM4WJG5N3CAX8905 Any GOOD battery charger will do.

So like $500, but you now own a nice box, battery, charger, and inverter. So play with the idea and see if it would fit your style. Just an option.

Here is what some guy did with $1000 and you could scale this to your needs.
https://www.youtube.com/watch?v=offgcMwuTGw

Sorry for the mess of a post.

Good luck and have fun. Be sure to let the sub know what you come up with.



u/razzix · 2 pointsr/gpdwin

As others have said you can do this with a relatively small setup. There is a LOT to consider - HOW portable, HOW efficient, etc etc. Help me out if the below suggestions don' t meet the need I can piece together just about any system for you :P

​

You could get by on a small sealed lead acid battery designed for uninterruptible power supplies. They range in size but average 9 amp hours. I say get yourself a little 35 amp hour and never worry about discharge rate if you are only powering the win2 even if the sun don't shine that day. For the solar - buy BIGGER than you need - learned this the hard way with my truck camper. Right sized is great until the season changes or its overcast etc.

​

Check out this little starter kit - it includes the solar panel and charge controller:

https://www.amazon.com/dp/B00DCDZOI0/ref=cm_sw_em_r_mt_dp_U_2ehvCbKCNM5MT

​

Down in the frequently bought together you should see a 35ah battery - will fully charge the win2 a few times and not even feel it:

https://www.amazon.com/85980-D5722-Sealed-Battery-UB12350/dp/B001VV0318/ref=pd_bxgy_2/135-2046487-8709925?_encoding=UTF8&pd_rd_i=B001VV0318&pd_rd_r=f062a34c-263c-11e9-b2b2-83751d0b2340&pd_rd_w=Nxcwh&pd_rd_wg=KqE5I&pf_rd_p=3f9889ac-6c45-46e8-b515-3af650557207&pf_rd_r=KWC3NGMZ50M5TJWJ1STT&psc=1&refRID=KWC3NGMZ50M5TJWJ1STT

​

12v car charger that I use with the win2 - works great:

https://www.amazon.com/Charger-Anker-PowerDrive-Adapter-MacBook/dp/B071WYF9HP/ref=sr_1_3?ie=UTF8&qid=1549038482&sr=8-3&keywords=anker+pd+2+car+charger

​

​

Plenty portable depending on your needs. Its almost as easy as color coding to setup. You can power the win2 and multiple devices if you so choose. Expandable at a later time if you choose with panel and batts. Will fit in any trunk or backseat. Hell it will fit in a big backpack (panel is 21x26). Large enough charge current to top off your battery quick even in partial sun - big enough reserve to keep you going for a couple days easily. This is just an example of an 'easy' bundle if you wanna save some more money I can show places to get these items cheaper.

​

​

If you wanna talk more DIY and are not afraid of LI-ION 18650s you can build you a safe lighter and denser battery for pretty cheap. It would be piecing together a charge controller and panel but I would say stick to 50w range - affordable and covers your power needs even in less than ideal conditions. If you wanna go more expensive but more portable flexible/foldable panels are out there too.

​

u/paperwaller · 2 pointsr/pics

I agree it's possible but even so the auction house would have maybe noticed it was a bit odd at least. Who knows maybe they just let them put it up without really handling the frame themselves. This video shows a lot of the internals and I really hope that battery isn't a baby lead acid hopefully (I'm sure it's not lol) that's just a case or it's a LiFePO4 pack at least or anything better. Is that person at 17 seconds holding a soldering iron? Good thing it's off for the camera haha but it could be a screw driver or something. There would be a bit more heft too that frame than normal. That's all I was thinking that the thick frame and a bit more weight might be odd so that's why I made the comment the auction house would have noticed. I have had two forgotten 4S LiPos hold their charge for 3 years pretty well so I'm sure that's not a big issue but like ya said they did run out halfway. I think you would have put it together better and I have a few ideas myself after seeing some of the internals in the video.

u/thinkmcfly · 3 pointsr/motorcycles

I know standard AAA membership does NOT include motorcycle towing, however you can add it on for $35/year (including membership fees). I don't know of any other separate services.

For a cheap GPS unit - ebay or newegg.com. TomToms are quality units and tend to be cheaper than Garmins. I got my TomTom One for < $100. You can get a cigarette light adapter for your bike (if you have a battery tender, you can get one that plugs right into the connectors for that) to charge phone/gps/etc. Just go to your local dealership and they should have seomthing like this.

As for tools: basic tools as you mentioned mentioned. Tire repair kit if you're worried about breaking down. Zip ties. Plexus instead of Windex for your faceshield.

Rotor lock will probably be the easiest type to carry, but know that if someone wants your bike enough they will get it, especially in LA. Make sure you have theft insurance. Don't forget to take the rotor lock off when you go to take off in the morning :)

I just did a 100 mile straight highway ride last week with a throttle boss and it made a HUGE difference in the stress in my wrist. I highly recommend it or something similiar.

Most important part - have fun! Explore. If you're giving yourself 4 days to get there, take your time and see the sights. Get lost. Find some good roads to hit up. Take pictures. Etc etc

u/1832pro · 3 pointsr/vandwellers

Hello - One thing I'm learning as I continue to read more, watch more videos and build more vans out... You can definitely get some cheap "trainers" but 9 out of 10 times, you get what you pay for. I hope these work out. Batteries aren't cheap, on doubt. If you head over to my friends at the "Explorist Life" and check out this video specifically speaking to the pros' & con's of AGM versus Lithium. You may want to rethink your investment.

It will benefit you immensely if you can realistically tally up the devices, lights, USB chargers, etc and determine what their power needs are and then try to determine your usage of each... This will give you a rough guideline in how many Amp Hours you'll need.

Personally I have switched to lithium because the math just makes sense. There are a lot of affordable solutions out there that aren't BattleBorn tagged. For instance there's Orient Power. Will Prose and Jerry G (YouTubers) have done some extensive reviews of Orient's offering and have good things to say. I can vouch for them as well. I currently have 200W in Renogy solar on the roof coming into a Victron SmartSolar MPPT 100/20 Solar Charge Controller 100V 20A. From there it feeds a single 100Ah bank. I also have a Lithium Battery Isolation Manager so I can charge my "house" battery when my "starter" batteries register as fully charged. As an additional power source I have a Xantrex Freedom 806-1840 HF 1800 Inverter/Charger. This allows me to covert my 12VDC to 110VAC but it also always me to plug into my home's 110VAC to charge and power the van. I know you are new to this so I don't expect you to go out and get all this setup... But I figured I'd go down the rabbit if you wanted some food for thought in regards to future proofing your setup.

So one last note for some context to this battery's performance... I have a small Norcold fridge that's always on, 8 LEDs in the ceiling, USB chargers, a Maxxair, two USB powered fans and a 110 outlet to power my laptop... When I had only 1x100W panel up top I will kill the battery before 10pm. I added a second 100W and wired it in series and since then I've not killed the battery. I've consistently woken up in the morning see my meter reading above 12.9V. I've been very happy with Orient Power's offering after 4mo of use so far. I bought a second 100Ah battery to add but at this point I haven't needed it.

Hope this helped..?

u/djd-ev · 3 pointsr/homeautomation

Awesome to hear another van dweller is in here! my current electrical design includes installing a two alternator system from nations and 4 100AH lithium batteries. That should give me enough power to run the speaker system, TV, Router and Modem and lighting for around 12 hours before needing to start the van and charge up the system. The automation is a total luxury, and adds the wow factor, but if implemented properly may be worth it to me. Budget isn't a huge issue, this will be the first house I ever build. My salary is pretty good and I'm spending $1500 a month to live here in southern california. Without the added rent expense I can justify making this thing an awesome place to live. Maybe a better idea would be adding a separate, solar electrical system with a 5th battery so that the wifi and automation system can stay on at all times.

u/1Tim1_15 · 1 pointr/vandwellers

Glad the info helped! Let's say you're using 100 watts (Xbox with TV). It sounds like you may be using only 90 watts, but we want to allow for electrical inefficiencies so we add 10% to your usage, so in this case that's 99 watts. Let's say 100 watts for simplicity and for a little extra margin.

The GoalZero website says their battery has 280.8 amp hours (Ah). You don't want to discharge a lithium battery more than 90%, so your real capacity is 252.7 Ah (280.8 * 0.9). Your system uses 8.34 amps (100 watts / 12 volts = 8.34 amps). To find out how many hours you can power your system on this, divide your Ah by amps, so 252.7Ah / 8.34A = 30.3 hours...which means your math is correct :) Keep in mind that it will take around 9 hours to recharge this battery.

A little more math: You can get a 100Ah lithium battery for $950, a 600 watt pure sine inverter for $220, and a lithium battery charger for $175. Throw in $20 for cabling and you're up to $1,365, so let's say $1,400 if there's any extra shipping. That's less than half the cost of the GoalZero and you'd get 10.8 hours of play from it, and recharge time would be 3.3 hours.

If you get two batteries, your numbers would be $2,315, 21.6 hours of use, with a recharge time of 6.6 hours.

I'm not saying you shouldn't get the GoalZero since it may be the perfect solution for your needs. Just trying to show you other possible choices.

u/TreborEnglish · 2 pointsr/vandwellers

That's a tight budget. It is possible but you don't have room for $1000 mistakes.

It isn't really hard if you want a small system in the range of a Suaoki or Yeti. They are 400 watt hours. Divide watts by volts to get amps. 400 ÷ 12 = 33.33 They actually contain a $65 35 amp hour battery like this:

https://www.amazon.com/gp/aw/d/B001VV0318/

That is not compatible with a 12 volt efficient fridge. It is too small. It's simple but it won't work past the first week.

You can get a 100 amp hour battery, 3 times the size, for about $100. A 100 watt solar panel for $100, a $12 to $20 charge controller, and you have a system that can run an Alpicool C20 little efficient 12 volt compressor fridge, $250. There are you tube videos about the Alpicool.

In addition to that you need some AWG # 10 wire, fuse holders, fuses, a $10 multimeter, a $10 hydrometer and as needed sockets for USB, cigarette lighter sockets, led lights and switches. You'll need a cheap crimper and an assortment of crimp terminals. That's a total of $600, including fridge.

For charging laptop and stuff search on amazon for "car charger" and your computer brand and model. They run off 12 volts and are more efficient than double conversion 12 to 120 then 120 to 19. They go 12 to 19. If you have a device where you can't find a car charger then you need an inverter. Smaller is better.

If you want a system big enough to have all the electricity you want, double the solar panels and get a pair of 6 volt golf cart batteries.

u/gusgizmo · 1 pointr/amateurradio

Seems like a car, marine, or deep cycle battery of 32 or more amp hours would do the trick. You'll have to evaluate your purchasing options, but I'd recommend getting sealed lead acid deep cycle batteries of some flavor.

This is a good deal:

http://www.amazon.com/UPG-D5722-Sealed-Battery-UB12350/dp/B001VV0318

My reasoning for that sizing is that 200w for an hour is only 16ah at 12v, so double that to prevent yourself from overdischarging the battery and you should be good.

If you want to double up on size, I'd recommend just buying a larger battery from the start and avoiding the complications that multiple batteries bring into the picture.

The solar panels seem to output around .9a, really depends on your insolation numbers but 5 hours of usable light gives you around 4.5ah per panel or perhaps around half an hour of TX time per day of charging.

u/jgagnon_in_FL · 4 pointsr/SelfSufficiency

11 lbs.

Yeah, I think I am ok with my 2x Fullriver 224 Amp 6 Volt golf batteries (224Ah @ 12 Volt or 2688Wh) w/ 2000 Watt Pure Sine inverter (to power actual appliances up to and including air conditioners) w/ my suitcase 100 W Solar solution in the back of my Jeep. It's more likely I will drive that apparatus around then I will carry an under-powered 11 lb "battery pack"

Also a retail price of $599. You could reproduce the aforementioned battery bank for the same price:

Fullriver Group GC2 6V 224Ah T-105 AGM Sealed Lead Acid Battery

Yes it weighs 120 lbs for the two of them, but you are getting 4.5 WH per $ as opposed to 0.69 WH per $

Lithium Ion is still EXPENSIVE a f, the advantage obviously is the weight savings, but in this case now you are talking 37.8 WH per LB vs. my setup of 22.4 WH per LB, so you are effectively saving half the weight but paying 5x the cost per WH.

Alternatively you could get a 200Ah Li-Ion battery for $2400 that weight 72 lbs, so similar weight savings at a much better price 1 WH per $

..and for the curious a 35Ah (440Wh) Li-Ion battery for $450 that weighs 10 lbs - so given that price this unit with its electrical "wizardry" built in is not that much of a ripoff.

u/Jenkins6736 · 2 pointsr/Coachella

It's better to be safe than sorry. You don't want to bring out all that gear only to find you can't turn it on.

You'll be fine with any of these with the top one being your best candidate. Just remember to be courteous to your neighbors if people are trying to sleep!

Xantrex 806-1210 PROwatt 1000 SW Inverter

MicroSolar 1000W (Peak 2000W) Pure Sine Wave Inverter

BESTEK® Dual 110V AC Outlets 1000w/1200w Max Car DC 12V to 110V AC Inverter Power

You'll probably want to get a fuse holder and a cable kit depending on how far you expect to keep the table from your car.

You could also go the more environmental route and get some solar panels to juice up a spare solar battery each day.

u/DrTom · 1 pointr/vandwellers

This is the most popular solar set-up. Then a battery like this. You may need an inverter, too, but that depends on your needs.

Water depends entirely on you. You can get five gallon jugs that re-fill at Home Depot for $7, for example. A lot of people get water for free at gas stations or parks.

It seems like you're just getting started thinking about this. I recommend the FAQ. There's lot of good stuff in there!

u/lirakis · 2 pointsr/GoRVing

If you want a single battery, get a 100ah lithium iron phosphate... its gonna cost you though...

AGM batteries are only useful for 50% of their advertised AH rating vs like 80%+ for Lifepo, also lifepo are lighter weight, and have more recharge cycles.

I run 2 of these right now to get 100 useful AH, and I am hopeful that in ~3 years when its time to get new batteries the cost of LifePo will have come down b/c they really are vastly superior in every way.

I'd really like to find something that can stand on its own without a sub, since none of my groomsmen will have a sub. Other than the Sprites, it looks like the rest of those were designed to be paired w/ a sub.

I saw the Sprites original design was a boombox, which I thought was pretty cool. I think that would be the most practical form that my groomsmen would use.

I don't personally have one, but I've heard good things about the Battleborn batteries.

Contrary to what a lot of people say, as long as you don't abuse them Lithium batteries (especially lifepo4) are pretty safe.

I'm going to have to weigh my options on that one. It would be nice to make my own connections since this is a DIY project, but want to keep it cheap as well.

​

>How are you charging the 'house' battery?

I'll have to look into that. I'm not sure if the alternator charges that battery or not, but it can be charged from the generator. I won't be using either of those options if possible, my plan is to recharge it using the 100 watt portable panel since it'll mainly be used for the water pump, wifi amplifier, and lp/smoke alarms.

​

>What's the gel-cell's model number and such?

It's a renogy 100aH 12v battery: https://www.amazon.com/gp/product/B01KN6QUW2/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

>Also, hooking up the solar to your house battery system is pretty easy, especially if it's 12 volts nominal. Depending on specifics there are better and worse ways to do it, but in theory it's very simple. :)

The solar battery bank will be in the storage next to the under the stairs battery, so it won't be too far. Another reason I didn't want to do this is the RV only has 1 12v outlet in the front, so everything i use will be going off the inverter anyway, and I have the 100 watt portable panel to charge the house battery for those small electrical needs mentioned above

u/gavinb · 3 pointsr/AskElectronics

You can get a SLA (Sealed Lead Acid) battery in various sizes, and they put out 12V. They could easily run for several hours on a single charge. Don't bother tying to make a charger (harder than you think!) just buy one, they're pretty cheap.

An example of a battery https://www.amazon.com/Verizon-PX12072-HG-Powerstar-Rechargeable-Terminal/dp/B00V93WVPO/ref=sr_1_54

which is rated at 7.5Ah, so it can deliver say 500mA continuously for around 15 hours.

Make sure you get a smart charger, like https://www.amazon.com/Battery-PeleusTech-1A-Portable-Maintainer/dp/B01822CSA2/ref=pd_sbs_23_2/132-4805477-2123568 which does trickle charging and has auto cutoff, etc.

u/Grape_Ape_Sex_Tape · 2 pointsr/Ruckus

For the battery I got one of these and I'm really happy with it so far:

https://www.amazon.com/gp/product/B00BFLVUDO/

It's pretty clean and simple to add the acid, so as long as handling that doesn't spook you, you're getting a brand new battery that's guaranteed not to have been dying on a shelf for months before it ever gets installed.

u/aaron3323 · 1 pointr/SolarDIY

Thank you so much for the information, I'll have to measure it out when i get home.I had intended to start with 1 and work my way up to 4 if it worked well.

So Batteries, probably the most technical portion of this part. So looking at [this] (https://www.amazon.com/Renogy-Battery-Marine-Off-grid-Applications/dp/B075RFXHYK) There is a lot of words in here that are challenging me. Whats the best way to assess what would actually be needed for the job? Can you chain multiple if you exceed capacity on 1 battery?I should take an electrical class...

u/dragontamer5788 · 1 pointr/AskElectronics

> Would a 6v 12ah battery with a LDO regulator work?

It should work. LDOs have a maximum efficiency of output_voltage / input_voltage. In this case, you'll only get 83% of the juice, at least 17% of it will be "wasted" in the LDO.

83% is pretty good, A buck-converter will be around 90% if you wanted to go there.

> How would I recharge it?

Depends on the chemistry. 6v 12aH sounds like lead-acid to me, so I'd bet you need something like this (I dunno if that's a good charger, just picked the first one on Amazon). 500mA is going to charge very slowly however... maybe find a better charger, lol.

> I wanted a very high capacity battery so it can withstand several charges but that can also be recharged, even if it takes a long time.

If you're going with Lead Acid chemistry, you'll want to make sure you get a deep-discharge model. Lead Acid batteries basically come in two flavors: shallow-discharge (like Car batteries), and deep-discharge / deep cycle.

Shallow Discharge need to stay at maximum-charge most of the time, otherwise their internals start to corrode. Deep Discharge still has the same problem, but there are more anti-corrosion measures. Even then, you really are only supposed to go down to 45% charge or so.

---------

Other battery chemistries (Lithium or NiMH) have their own issues. Do a little bit of study on the battery type you plan to use

u/t0ny7 · 4 pointsr/photography

What you should do is buy a sealed lead acid battery, a power inverter, 12v clips to cig lighter and a charger.

I just picked those products as examples but that would work and would cost around $50. It could probably be cheaper if you look around.

Also the batteries in most small UPS are around 2 amp/hour while the one I picked is 8Ah.

And that would be pretty easy to use.

u/NotDavidWooderson · 2 pointsr/cycling

That said (and I agree), here's a hypothetical for the EE crowd to ponder...

They all use AC Adapters. For example, the Kickr Snap uses a 12v 5A adapter, so couldn't you run it off of a $15 battery, like this? Yes, you would have to fit your own custom wire, and yes, you would have to recharge that periodically at the house (or maybe via solar).

And yes, I realize that this risks blowing up a $500 trainer, hence the hypothetical classification.

u/elkster88 · 2 pointsr/motorcycles

My 0.02:

Just buy a good quality AGM battery. Even though Amazon says that one doesn't fit your bike, yuasabatteries.com says that it does (YTZ7S HONDA CBR1000RR /2008 - 2017, 1000cc). Also partzilla.com says it's a YTZ7S.

Lithium Iron Phosphate are great for low weight and small size. That's about the only good things about them in my opinion. They cost more, and they are finicky about charging, plus they don't put out much current when it's cold out, until the battery warms up.

But make sure you check the fitment for yourself, I'm not responsible if the Amazon link gets you to another battery that doesn't fit.

u/URIDIOTLOL · -4 pointsr/Futurology

A 12V 200Ah battery(2.4kWh) can be had for ~$312 on amazon

a 5kW inverter is $1425 on amazon

That gives you a 31kWh storage solution for $5500. Even if you opt for more expensive batteries and inverter(s) I don't see how you end up with something with less storage than a powerwall?

But I guess It's marketed for a very special crowd that care more about how sleek and trendy their battery storage is than what it costs.

u/MikeOnBike · 2 pointsr/raspberry_pi

I recommend moving to 12v components and then regulating the power back down to 5v for the Pi. There will be many more options and prices will be better.

Start with a solar panel:
http://www.amazon.com/HQRP-Mono-crystalline-Anodized-Aluminum-Radiation/dp/B002HSUT40

Use a charge controller to attach it to your battery(s):
http://www.amazon.com/Sunforce-7-Amp-Charge-Controller/dp/B0006JO0XI

Attach a voltage regulator to the battery and your Pi:
http://www.amazon.com/Ship-Hobbywing-Switch-mode-UBEC-Lowest/dp/B008ZNWOYY/

As far as batteries go, buying local will save you some shipping. If this is an outside battery you can use a deep cycle/RV battery. If inside then you need something sealed. You should have several days of reserve for bad weather. Maybe something like this:

u/pbewig · 1 pointr/vandwellers

It is unlikely that you will be able to power a heater with solar power; heaters simply require too much electricity. A sleeping bag rated for the temperature you will experience is probably the most effective thing for you.

A quick look at Amazon shows the Nintendo switch has a wall outlet power adapter that outputs 5v at 1.5a. Assuming that is correct, you can charge your electrical devices from a wall outlet at McDonalds or Starbucks, or from a cigarette lighter adapter in your car. If you won't be in cities or won't be driving daily, a small solar panel and battery (I like that battery for its dual inputs, which makes it charge twice as fast) will likely be sufficient. Price for solar panel and battery about $100.

If you need more electrical power, put a roof rack on your car, then buy a battery and a 100-watt kit from Renogy (the kit includes mounting hardware, cables, a solar controller and instructions to wire everything together). Price for solar panel kit and battery about $400.

u/phidus · 2 pointsr/AskEngineers

You will almost certainly need a generator or a running car as /u/Laymanism mentioned. A dual halogen worklight will draw about 1000 watts [1]. A car battery will hold about 18 AH at 12 V [2]. Even with a perfect inverter you would only get about 12 minutes power. You could hook up a bunch of batteries in parallel, but I would recommend a generator and a long extension cord.

u/cobolNoFun · 1 pointr/DIY

yeah that what i was going to reccommend. So if my math is correct (probably not). to run that stereo for 3 hours you would need a 9 amp batter at 12 volts. So to not destroy the battery lets round that up to 27-45 would be better. Then you would only need a small inverter and charger.

200w of solar panels is actually quite a bit for most lithium batteries. You're probably better off (financially) in investing in just a single 100w panel and deep cycle lead acid battery like this one.

In fact, a single 100w panel can keep two of the listed batteries charged on most days with moderate sunshine, no sweat.

u/OnlythisiPad · 5 pointsr/carcamping

You need to give more info:
Is this a dual battery system charged by your alternator while moving?
Will you use solar to recharge?
What type of trailer and how much “stuff” will be running?
Will you move the trailer every day or use it as a home base?
How much room do you have? (For 1 battery, 2 batteries, etc)
These are just a few questions to start.

Based on a guess (external, camper mount, and road trip), you can use a vented, marine, deep cycle like this: Duralast 29DP. And that will support some LED light strands, and a small fridge for a night or two, possibly more.

Based on my own application (usually daily charge from an over-sized alternator and run a National Luna fridge, and multiple lights), look for a sealed, lead acid, deep cycle battery. For $200 I can order a sealed lead acid from Amazon and that will run everything I need for a few days, then charging off my truck for a days drive.
[Renogy 12 volt Deep cycle AGM] (https://www.amazon.com/dp/B075RFXHYK/ref=cm_sw_r_cp_tai_jwC3DbH19QZ6B)

Lithium batteries can’t be charged when the temp is below freezing. Besides, they cost a fortune (but last a long time tolerating heavy abuse)

Depth of discharge.

I'm not sure how you get triple the cost for lithium, even if you can only buy from Amazon and only count up front cost. You're looking at 4x$170 lead batteries or 2x $500 lithium ones (in both cases the cheapest ones Amazon sells), which means $680 vs $1000. For triple the cost ($2040) you could buy name brand lithium instead (Battle Born or Renogy). And of course you're looking at 3000-5000 cycles to 90% DoD from the lithium rather than 300-500 to 50%... that extra zero really does affect the cost per cycle.

u/Prima13 · 3 pointsr/amateurradio

I didn't have a tutorial, but here's what I did.

  • 12v 35Ah battery - extremely heavy but cheap and powerful. If you're looking to go lighter, or if you don't need as much power, I'd suggest something smaller.

  • Big plastic ammo-type box holds the battery and other parts and keeps the wiring hidden.

  • One of these allows me to hook the battery in between my home power supply and my home rig, turning the whole thing into an uninterruptible power supply that also charges the battery. If the power goes out, rig instantly switches over to battery.

  • Added a solar panel charge controller for charging the battery from solar while I'm in the field. I have a 60w panel that I propped up against the truck on Field Day, worked great.

    Here's the end result with some input and output connectors on the outside of the can, as well as a volt meter, USB charge ports and a switch so that the parasitic load from the Astron box doesn't kill it while not in use.

    The hookup inside the box is relatively simple:

  • Solar charge controller is wired directly to the battery. Does nothing if there's no solar panel connected to the box.

  • Astron power box is wired to the battery with 30A fuses on both positive and negative wires. Output side of the power box goes to the output jacks on the outside of the box, but passes through the lighted 30A switch so I can shut it off.

    It's really that simple. This box kicked ass on Field Day, ran my Kenwood TS-50 and AT-50 all day with the solar panel keeping the battery topped off. Ran the system long after dark until I was too tired to work any more.

    If you have more questions, look me up.

Test video. It's much louder than it sounds in the video. Much louder than a typical car's horns. I only use it for situations where I am not seen by a driver and in danger. Not for casual "fuck you, buddy" type of situations.

Originally I had this set up with industrial zip ties, but it was not a very robust setup, so I removed it before this past winter. The bike is currently sitting in pieces. When I reassemble it I will mount the horn components in a single, weather-resistant enclosure, with a quick-release attachment so I can take it with me when locking up outside.

u/pseudo_mccoy · 3 pointsr/vandwellers

This blanket draws 4.6 amps at 12 volts. One 35 amp hour SLA battery will power it for 7.6 hours. 35 amp hours / 4.6 amps = 7.6 hours. If you wire two batteries in parallel you'll double your capacity to 70 Ah. This will run your blanket for 15 hours.

You'll hurt your battery if you fully discharge it every night. So maybe take that into consideration especially if you have other stuff you want to be charging. A simple guideline is to have 1 watt of solar for every amp hour (Ah) of battery.

If your 100 watt solar panel can feed 8.3 amps to your 70Ah battery it'd take a little over 8 hours to fully charge. 100 watts / 12 volts = 8.3 amps. 70 Ah / 8.3 amps = 8.4 hours.

I suck at math but am fairly sure I'm doing this right. Hope this helps.
