6v vs. 12v
I have considered 6v, but I was concerned about the size and weight. There's no question that 2x 6v batteries is the way to go if you have the room and can afford the weight. For example, the XTR6-235 from VMAXTANKS weighs 78 lbs and is 10.2" wide and 7.1" deep. That's 2x the weight *and* I'd have to completely rebuild the angles that form the battery tray. To complicate things, I'm not a welder. That said, they would provide 2x the AH over the batteries I was considering.
