Devil Dog - that battery box looks like an ordinary marine plastic battery box. I bought a fancy Moroso one for my car, with Dzus fasteners holding the top on, and a vent line out the floor pan.

However, when it comes to trying to keep battery acid away from things, all these boxes tend to have a problem. In a boat, it may be fine to toss the battery in the box, and strap the box down to the deck or wherever. Not so in a car, especially a race car. So you end up punching two holes through the bottom of the box for the rods which, with a cross piece up top or the like, hold the battery firmly in place. Now the acid tight integrity of the box is compromised somewhat.

But if your battery is sealed, that part doesn't matter, and a nice plastic cover surrounding the battery keeps stray metal objects from trying to weld things or cause sparks.
