The OzCharge Beast Battery Box (OC-BEAST-DCS) is a purpose-built 12V portable power system that packs a dual 30A DC-DC charger and a 30A Solar MPPT charger into a single, ruggedised enclosure — delivering serious off-grid charging performance for Australian caravanners, 4WD tourers, and campers. Compatible with both AGM/GEL and Lithium LiFePO4 batteries up to 120Ah, it features selectable charge profiles (14.4V for AGM/GEL, 14.6V for Lithium) and smart alternator compatibility with an ignition sense wire, ensuring your deep cycle battery is charged safely and efficiently whether you're driving down the highway or parked up under the Outback sun. With dual 50A grey outputs (2 × 600W with auto-reset circuit breakers), a 100A inverter output, two 12V DC outlets, and a dual USB port, it puts a complete power management hub right at your fingertips.
Built for the realities of Australian touring, the Beast Battery Box is the ideal power hub for caravans, camper trailers, 4WD dual-battery setups, and off-grid base camps. Whether you're running a 12V fridge across the Nullarbor, powering lighting and devices at a remote free camp, or keeping a motorhome's auxiliary battery topped up through a 450W solar array, the Beast handles it all from one neat, portable package. It ships with a 6-metre DC-DC cable with 50A yellow connector and ring terminals, a 1-metre solar cable with MC4 connectors, hold-down mounting brackets, and an OC-50A-SAE charging adapter — so you're ready to plug in and go from day one.
