Reddit mentions of NITECORE New i4 battery Charger For Li-ion / IMR / Ni-MH/ Ni-Cd 18650 18350 16340 RCR123 14500 AA AAA D C w/ Ac and 12V DC (Car) power cords, EdisonBright BBX3 battery box, 2 X AA to D type batteries

There are 3 basic rechargable lithium chemistry batteries out there currently

LiPo: Lithium Polymer

LiOn: Lithium Ion

LiFe: Lithium Iron (something). This is a special lithium battery that sacrifices capacity and voltage for safety. You can put a nail through one of these batteries and it won't explode or catch fire. They are almost ALWAYS in metal cylindrical casings.

Now. As far as regular battery chargers for consumer batteries, I recommend the (relabeled by countless companies) Nitecore one.

It's insanely popular on message boards dealing with consumer electronics, high end flash lights, and the like. It's a great, great item at a decent price point.

It comes in 2 versions, a 2 bay and a 4 bay charger.

2-bay charger (I2): http://www.amazon.com/NiteCore-IntelliCharger-i2-Charger-charging/dp/B009JMDD9U/ref=sr_1_1?ie=UTF8&qid=1397224760&sr=8-1&keywords=Nitecore+charger

4-bay charger (i4): http://www.amazon.com/NITECORE-Intellicharge-universal-EdisonBright-converters/dp/B00GODG3X0/ref=sr_1_3?ie=UTF8&qid=1397224760&sr=8-3&keywords=Nitecore+charger

It does not do 9v rechargeable batteries, but most chargers that do (that are consumer grade chargers) sacrifice everything to do so. It also does not do D-cell batteries, but a 2 dollar battery holder fixes that problem quickly. You put the D-cell batteries in the battery holder, then run wires to the charger. There is no functional difference between C and D batteries for most applications.

Hell, MOST D-CELL BATTERIES HAVE AN AA cell IN THE MIDDLE AND FILLER. An actual AA battery in the D-cell casing. I have plastic versions of that, so that you can use high capacity AA batteries in D and C-cell devices.

I recommend going that route for those batteries.

AA to D cell converter/adapter: http://www.amazon.com/eneloop-SEC-DSPACER4PK-Spacers-battery-cells/dp/B002V8C3W2/ref=sr_1_1?ie=UTF8&qid=1397224984&sr=8-1&keywords=D+cell+converter

AA to C cell converter/adapter: http://www.amazon.com/eneloop-SEC-CSPACER4PK-Spacers-battery-cells/dp/B002V88HFE/ref=sr_1_2?ie=UTF8&qid=1397225050&sr=8-2&keywords=eneloop+c+converter

Those are eneloop brand, which is an extremely high end rechargable battery company. Their cells are relabeled and have been for over 5 years by Duracell, Energizer, and countless more.

Even Apple's rechargeable AA battery system uses relabeled Eleloop batteries! 30 bucks for 2 4 AA's and a charger is ridiculous when straight-labeled Eneloops are half that price.

The Eneloop adapters are the best I've ever used. Most cheap battery adapters are so flimsy they break inserting the damn battery.

I would stay with AA batteries and use the cell adapters. As it is, a high quality rechargeable AA has more capacity than MOST ALKALINE C and D sized batteries to begin with.

I hope this helped! The chargers I linked will do from AAA to C, up to 18650 and 26650 INDUSTRIAL LIPO cells. It's a GREAT charger that will do everything you need it to, faster and far better than anything you'll buy at Best Buy or Walmart.

Seriously. Buy that charger, some Eneloops, and never worry about it again.

I don't use rechargable 9v's but I'm probably going to have to soon!

Best 14500 IMRs are Windyfire. Crappy name, great 14500 battery. Efest and AW also good for 14500 sizes.

Note that there are many different versions of each, even by the same manufacturer.

Good 18650s are different from good 14500s.

Nitecore D4

Will also charge Ni-MH, Ni-CD, and LiFePO4

Yes, there are lots of vendors who provide 0 nic juice. But your hookah has nicotine, so you might enjoy something like superlow 0.1% or 1mg/ml.

Anyway, to get hookah experience you'll need max VG juice, it can be drawn straight to lungs, and some powerfull hardware to get heating going. Without paying a lot the only easy road is mechanical mods (meaning without electronic boards in them) and dripping atomizer. You'll need to research Ohm's law and battery safety. That's like most important things, so you don't blow your face off. Here is the list of what you'll need.

• Any 18650 compatible (almost all are) mechanical mod clone (meaning china cloned one of popular models). I'll recommend Stingray X by Infinite. But it's quite expensive. And really you can buy any other mech, just check how good that particular clone is, because there are different china clone makers, some models are better than others.
  
• RDA (Rebuildable Dripping Atomizer). I'll recomend Veritas clone. Known to produce a lot of flavor. Here is the video explaining the concept.
  
• Wire. You'll need different kind of kanthal by temco, from 26 gauge to 32. Just look it up on amazon.
  
• Organic cotton. Organic means that it wasn't bleached. You can buy just organic cotton balls or you can buy quite expensive japanese cotton.
  
• Battery. IMR battery, not ICR. If you research battery safety, you'll get the idea why. The current recommended options are Sony VTC5 and Sony VTC4. But they are really hard to find. Other good options are Samsung 25R and LG HE2.
  
• Good battery charger, like this.
  
• Ohm-meter. You absolutely need that thing.
  
• Expensive juice from good vendors like The Vapor Chef, Five Pawns, Bombies.
  
  That will outmatch hookah by a wide margin.
  

dude.... use a stryfe with a worker update kit. use imr batteries.
I get up to 140 fps with this setup.

you will need to rewire and cut the shell, but it is worth it.

I wouldn't order that from fasttech, you can get better quality stuff from us suppliers for a little more and have it in a week. hcigar nemesis is $30 from 101 vape when in stock or $40 elsewhere and better than the fasttech one. That fasttech patriot is 20mm I believe, you can get a nicer tobeco 22mm patriot on ebay for $17 shipped or so (I just got two, 101vape also has them). Get sony VTC4 batteries- sun vapers has them in stock for $10 right now. you can get a nitecore i2 with amazon prime for the same price as fasttech.
