You would need a battery isolator to charge both 6v and 12 v batteries from the same source. Hope this makes sense.

I like the idea of using a battery isolator and having the 12V as a backup. I will put a separate outlet to near TV and entertain area that will come from an Inverter from the pair of 6 volts, that will be for TV, laptop and phone charger. And the House 12V will run LED lights and water pump, heater fan.
Question, Will a battery isolator work with a single 12v on one side and 2 6 volts on another (2 banks - my thought)?
Also yes, I will also carry a Champion 3500w Inverter/Generator Dual Fuel for Air conditioner needs or other.
