Power your Grenadier with smarter energy management

Auxiliary battery system for Grenadier by Agile Offroad – SKU: G15-1004X

Important Notes

Important: System requires the Victron LiFePO4 Smart Battery (sold separately). You can purchase the compatible battery directly through Agile Offroad.

Agile Offroad’s Auxiliary Battery System expands the electrical capability of your Grenadier using a foundation built around the Victron LiFePO4 Smart Battery (sold separately). Each configuration arrives pre-configured with the correct wiring for your selected build, making installation straightforward and minimizing guesswork. The base system powers accessories while optional add-ons, including the inverter, Switch-Pros, Cerbo GX, and solar, enhance capability for more advanced overland setups.

The Auxiliary Battery System for the Grenadier by Agile Offroad provides a dependable platform for powering accessories without placing strain on the factory electrical system. At the heart of the system is the Victron LiFePO4 Smart Battery(sold separately), offering superior cycle life, fast charging stability, and lightweight performance compared to traditional AGM setups. Even Grenadiers equipped with the OE secondary battery benefit from the increased output, cleaner power distribution, and greater expandability this system provides.

Every major power management component in the system is sourced from Victron, a global leader in premium electrical hardware. This ensures consistent accuracy, high efficiency, and long-term reliability whether on the highway or deep off the grid.

From this base system customers can tailor their build with modular add-ons: a 1000 W continuous Victron inverter significantly outperforming the factory 400 W unit; a Switch-Pros module for streamlined accessory control; a Victron Cerbo GX for full system visibility; and Victron-based solar charging for extending runtime on remote trips.
