The Coast RV steel chassis mount battery box is built for travellers who want their power system protected in the toughest conditions. Made from heavy duty powder coated steel, it shields the battery from stones, water, and road debris while delivering the secure mounting strength required for long distance touring. The clean lines and durable finish create a dependable housing that feels at home on both new and older RVs
Designed to fit compact case lithium batteries in the three hundred amp class, the interior layout maximises usable space while keeping the battery firmly supported. The chassis mount format places the battery out of the way, freeing interior storage areas and keeping weight low where it belongs. The box accepts a wide range of battery bases within the specified width and depth, making it suitable for most high capacity lithium units.
For owners building a larger power system, the design supports dual battery setups when paired with the optional Coast RV bracket kits. These allow a single box or two boxes to be installed side by side beneath the chassis, giving you the freedom to expand your power supply without complicating the layout of your RV. The result is a secure and organised system that withstands rough roads and long journeys with confidence.
Built with Coast RV’s focus on practical engineering, this battery box offers the protection, structure, and reliability you need when your power system is the backbone of your travel experience.
