How many runs of wire from the alternator to the rear batteries do you have? If it's less than two, run another one. Try running two sets of ground wire all the way up front as well.

Maybe I just don't see it, but what's keeping those batteries in place other than gravity?

Yep just gravity! Havent been driving though once the box is put in the seats will be up and the batteries will be wedged in very nicely. Will just have to put a block on the right side to prevent them from sliding left to right.

Personally, if it were me I'd build some sort of floor and 2x4 frame system to hold everything in place...and to allow for future expansion...but that's just me :)
