Looking at batteries, I'm kinda leaning towards optima yellow tops:
They're lighter, I don't have to worry about off gassing like regular deep cycles, and I can easily get them locally. They don't seem to be as bothered by high amp draw as some other batteries as well.
On the downside, they seem to be about twice the price per AH. I'm leaning towards 6 of the Group 35 Yellow Tops right now. Which will put me at a 72v, 48ah pack. Nothing stellar on range, but I'm only wanting 10 miles anyway.
