Battery charging question??

I was wanting to add solar panels to my fish houses to avoid hauling batteries back and forth for charging or charging with a generator but in researching the set up I see there are flammable gases given off from charging regular open cell batteries. My batteries are located in the same cabinet as the cook stoves that are in bedded so I am thinking the continues charge from the solar panels is not a good idea in rental houses? Do any of you use solar power for charging and are my concerns valid? I have already made the switch to led bulbs and my initial test of the bulbs is they will last many more hours than the old style bulbs and with a 2-battery bank maybe I don’t need charge the batteries that often anyway.

The only concern is if you are over-charging your batteries.

Smart chargers are the only way to go.

I’ve had a 12v battery blow up in my face (Lucky to be able to see) due to overcharging and a spark was all it took to disintegrate a battery.

Avoid spark by hooking jumper cables up to charged battery first and dead battery last. Avoid batteries letting out flamable gasses by not overcharging.

Home Depot online has a 150 watt solar panel and a Coleman charge controller that addresses your concerns…about $400.00 bucks and your set. Also, I would go with sealed agm batteries, no filling or explosive fumes.
