Here is a new thread with a consolidation of all our billet battery box models. It includes all the new models and some larger pictures.

Here is a link to view ALL the Billet Battery Box Categories for Optima Batteries.


The original style of the open top Optima Box




The Covered Step Plate Top Boxes

These side mount boxes are machined out of structural angle. They are not a regular box with some bogus angle bolted on the bottom. We make them with the mounting pad facing up (behind the battery) or down (below the battery) for maximum flexibility in rigging different types of boats.
