M&M Boys battery boxes are designed and built by demo drivers to withstand the rigors of a demolition derby. 
We use our products in our own derby cars. 
All of our battery boxes are fabricated from 12 ga steel.

The battery is completely enclosed inside the box. 
After placing the batteries in the box, cover them with a rubber floor mat or piece of styrofoam to prevent the positve posts from coming in contact with the lid.
