Battery placement?

[TrackerTom]

Any concern if the batteries are not level? In my jon, I am thinking of putting the batteries up front where the hull slopes. Do I need to put shelves in to level them? Or, can I just leave them aligned with the hull? The batteries are the kind you add water to, and they have caps on the cells so I don't really see a problem.

Tracker rigs them with 1 battery in the front on some of the grizzly's now. I thought it was all of them ,but some of them had the smaller compartment like mine started out like. I have thought about putting wedges under them to even them up, but I'm not sure it's necessary.
