A typical. Standard size 12 volt battery will have about 100 AHs of capacity, unless its a huge 4D or 8D.
4, 12 volt batteries would give you max 400 AHs and that's only top of the line batteries. Many are only 60 to 75 AHs, so around 300 AH.
Almost every GC2, 6 volt deep cycle batteries have 200+ AHs. Even the cheap ones. You do need 2 to make 12 volts.
So, to get 400 AHs, comparable to 4, top of the line 12 volt batteries, you only need 4, 6 volt batteries.
For the same space, less money, and true deep cycle batteries, you get more capacity.
AGM will be near the same capacity as flooded batteries, That's not a factor in capacity.
