Which is the better battery configiration
I am trying to learn more about 6 volts batteries versus 12 volts. I know the 6 volts can be drained further and recharged more (better lifetime). At least that is what I think is true. But it seems...

The reason why I say four of either is because I would have room for 4. That is why I have the question of 4 12 volts which would give me 4 times the amps of one....or 4 6 volts which would effectively give me 2 12 volts. I hope that clears it up. If all things were even....I would have 4 x 12 volts @100 minutes a piece (just pretending here) so that would give me 400. If each 6 volt was 100, I would only have 200 because I know in series only the volts double not the amps but then they would be partially in series so then I would have the equivalent of 2 12 volt batteries @ 100 a piece for a total of 200. So it seems the 12 volt battery is a better idea until I think about how much lower you can drain the 6 volts.
Correct to a point until you look at real life. Typically unless you want to spend $400 per 12v you will find most 12v batteries are 75 to 90 ah. A typical 6 volt is 200 to 220 ah, so...
12v @ 75ah x 4 = 300ah or 4 x 90 = 360ah
You are correct that the 6v in series doubles only the voltage so
Two 6v @ 200 ah = 200ah. Four 6v at 200ah = 400ah.
Two 6v @ 220ah = 220ah. Four 6v at 220ah = 440 ah.
