or
- LCD Screen Display: This solar panel charger controller with LCD digital screen which is with energy-saving backlight to display all parameters, display better, more clea and more power-efficient
- Fully Automatic: This solar panel regulator with output switch, easy to operate. The battery indicator light on the controller will be on if successfully connected
- Power-efficient: Microcontroller digital accuracy, when solar panel regulator is charging, the arrow between the panel icon and the battery icon will flash fastly, when the battery was a full charge, it will be slow flashed, will stop charging. The function of the solar charge controller is to protect the voltage overshoot and discharge. Available for DC lamp and phone charging (Please correctly connect the positive and negative terminals, makes sure all terminals are connected tightly.)
- Rated Discharge Current : 20A; USB Output Voltage: 5V; USB Output Current: 1.5A; DC Output Voltage: 12V-24V, DC Output Current: 20A. To connect your load and the cables with the right polarity and then connect with the load output port of the controller. Pay special attention to + - polarity to avoid reversed connection
- Protection Functions: Overload and Short circuit protection, Lightning protection, Under-voltage protection, Over-charging protection, Reverse Polarity protection. Use PWM and WPC mode, improve system efficiency and prolong the life span of the battery

You really really really really should have some solar. You need two sources to charge your batteries when cruising. With solar you would have solar+engine alternator.
Here's a really nice flexible you can just sew into your bimini or tape to your deck. Flexibles only last a few years, but these will easily last you a few seasons. By the time they go bad, newer panels will be more efficient and cheaper anyway.

Add a charge controller and your batteries will always be full. Something like this, it's a 20amp so you could put two panels in series easily for more power:

Yep. Although the smaller solar panel I linked to comes with a controller (a bit simpler one), I used these. It looks like maybe amazon doesn’t carry them anymore so if you want that one might try eBay. I’ve bought it as “Anself Solar charge controller” as well as “Docooler Solar charge controller” it’s just a 12v controller.
I actually have started using this one on my bigger setups because it has more info:

But they are all basically glorified switches that monitor the output of the panel and battery and connect them when the energy on the panel is high enough and disconnect when it’s lower so you’re not draining the battery.
The project box is this one:

With this backing plate inside to screw into to mount the timer and controller:

Oh and if you want it to be water tight when you run cables through holes in the sides you’re gonna want something like these to go with it:

I’d imagine you could get a single one from an electric supply store if you didn’t want a set.
