Quick question

OK. I understand the difference between true deep cycle batteries and the marine batteries. I wasn't sure exactly what these had as far as amp hours because very few companies report amp hours on 12 volt batteries.I'd end up with about 320 amp hours since they add when you go in parallel but only 215 with to 6 volts in series. right now, the 6 volts at Sam's are over $90 each, locally. Frankly, given the higher cost of the 12 volt battery, and I would need to plus another battery box and cables, is about a wash for buying the two 6 volt batteries, 2 new battery boxes and cables. with a hundred watts of solar charging to extend my battery life a bit, I was thinking that for this go-round anyway, I could stick with the two 12 volts and get the two 6 volt a few years down the road after these go belly-up. After comparing prices, though, I'm seriously thinking of just going ahead and getting the 6 volts now.
