The W.O.D. Optima Battery Box Mounting Bracket is a heavy duty mounting tray designed around the popular Optima platform. This battery box fits Group Size 34/78 batteries while also accommodating other batteries within the same footprint range. Whether you're building a rock crawler, Ultra4 car, race truck, buggy, Jeep, or custom fabrication project, this battery box delivers the strength and versatility serious builders demand.

Designed for universal vehicle fitment, this battery mount box allows installation from the bottom or back side, giving builders more flexibility when packaging tight engine bays, rear chassis sections, cargo areas, or custom tube chassis layouts. When paired with the W.O.D. battery box hanger (P/N WA01061H), it can be mounted directly to chassis tubing, making it an ideal solution for tube-frame vehicles and one-off builds. Its rugged steel construction offers long-term durability and can be painted, powder coated, or customized to match your build. Whether you’re replacing a worn battery tray or building a new rig from scratch, this battery box delivers a clean and secure mounting solution.

Tech Insight

Will this battery box fit batteries other than an Optima YellowTop?

Yes. While this battery box was designed around the Optima YellowTop Group 34/78 battery, it will also accommodate many other batteries with similar Group 34 and Group 78 dimensions. Always verify battery measurements before ordering to ensure proper fitment.


Why is a heavy-duty battery box important for off-road vehicles?

Off-road vehicles experience extreme vibration, impacts, chassis flex, and rough terrain that can damage poorly mounted batteries. A properly secured battery box helps prevent battery movement, protects electrical connections, and improves overall reliability during rock crawling, racing, trail riding, and other demanding conditions.


Can this battery box be mounted in a tube chassis?

Yes. This battery box was specifically designed with custom fabrication in mind. It can be mounted from the bottom or rear and can also be paired with the W.O.D. Battery Box Hanger for direct installation onto chassis tubing, making it ideal for rock bouncers, Ultra4 cars, race vehicles, and custom tube chassis builds.


What vehicles can use this battery mounting tray?

This universal battery tray is commonly used in Jeeps, rock crawlers, race cars, Ultra4 vehicles, UTVs, trail rigs, mud trucks, overland vehicles, trailers, and custom fabrication projects. Any vehicle running a Group 34/78 battery and needing a secure mounting solution can benefit from this design.


Can the battery box be painted or powder coated?

Yes. The battery box ships raw and can be painted, powder coated, or customized to match your build. Many builders choose to finish the battery tray during chassis fabrication to match the vehicle's frame, suspension, or overall color scheme.
