Oh, yeah, that could be the possible difference.

I'm planning on a much smaller scale version myself. I've got a 400 amp Harley Davidson battery, I just haven't figured out where to mount it yet. I'm also holding out because I may need a new starting battery. If mine goes out then I'll just get a chevy battery because of the dual batter connections to make wiring a ton easier.
