Roughly speaking, all other things being equal, range is proportional to the amount of lead you have. The voltage of the batteries is not so important. However, there is typically a little difference, because a 12v battery has more mass and volume in plastic case and interconnects, and less in active lead. For example, a US Battery US-2200, 59lb has a reserve capacity of 122 min at 75 amps, or about 915wh (15.5 wh/lb). A US 31TMX, 64lb, gives 58 min at 75 amps, or about 870wh (13.6 wh/lb). Cycle life is typically better for golf car (6v) batteries. As a rule of thumb, in most lead powered EVs, 6v golf car batteries will give you the most economical operation.
