12v marine/deep cycle batteries
I know they are not true deep cycle and I have no intention of going to 6 volt batteries. Which would be your choice between the Interstate SRM-29 and the WalMart Everstart Maxx 29DC? I can get the I...

And if you are realistic about how far you can draw down a pair of 12 volts vs a pair of 6 volts, the AH advantage goes back to the 6 volts.RoyB wrote:
The real beauty is with two each 6VDC golf cart deep cycle batteries in series weighing 61 lbs each will give you 12VDC at around 220AHs for around $160... A single Trojan T1275 12V deep cycle battery weighing around 82 lbs each will give you 12VDC at around 150AHs and will cost around $250 dollars. Two mounted in Parallel will give you around 300AHs for around $500...
If you are on a budget then the cheaper golf cart batteries are the way to go...

Everything posted here is correct except one thing. Finding 6 volt true golf cart batteries for $80 each will be next to impossible.
Using 12 volt batteries will give much greater capacity than using 6 volt batteries.
2- 6 volt batteries in series= double the volts but the amp hours remain the same
2- 12 volt batteries in parallel= double the amp hours but the volts remain the same
