"where does the energy go? well, the 12V with lower AH will discharge faster than the 6V combo. so the 6V will be charging the 12V as well as supplying part of the load with the 12V."
So after the 6V charges the 12V will the 12V then supply that energy given to it by the 6V to the load?
yes, but remember charging efficiency is not 100 percent.
and 6V have much higher internal resistance than 12V so there is also an imbalance under discharge load, especially if the draw is very high.
250AH GC starting current near a few hundred Amps, 12V 80AH marine battery starting current 600 to 800 Amps. quite a difference as the load increases.
not a good combo.
the lower the current draw, the better the situation is.
