Where to mount the battery?

[Silver]

Hey all. Digby Baker-Porazinski from team 5236. This is my (our) first post in CD, so everything I say will probably be in some way some sort of taboo.
This probably isn't even in the right section.

Anyway.

This is our first robot of our first year of competing. Design is coming along smoothely, but we've hit our first roadblock: where to mount the battery. We agreed it should be low to keep the center of gravity low (the thing's 14 pounds) and situated in the rear to counterweigh the game mechanism, whatever that may be. But the battery is large and cumbersome, and we're having trouble deciding where to safely and efficiently place it.
That being said, any tips or examples of where you've put your battery in previous years would be much appreciated.

Thanks from Man o' War, team 5236, Cambridge, NY.
