This battery box is strong enough to be mounted in any position.
The battery box could be bolted down through 6 laser-cut holes in
the bottom of the box or it could be welded to a battery tray. The
Optima battery is held in with a clamping action to ensure the
battery stays where you put it. It is formed from 1/8 high-strength
steel plate. Battery clamping hardware is included.
