My cart uses four 12 volt Trojan batteries. The cost is $160 each plus tax, pushing it close to $700. A friend of mine priced a different brand at Sam's and he said there wasn't much difference in price, plus he would have to install them himself. I don't even have to take my cart anywhere as the supplier will go to my club and do the job there. So that is nice.
Most people I know who have electric carts haven't been able to do any better. Just not many options around here.
