ARB Universal Auxiliary Battery 12" Box Kit With Wiring Loom & BCDC1225D Charger mounts, protects or forms part of an auxiliary-power setup for vehicle and camping equipment. A vehicle-specific battery component gives a planned position and cable route instead of placing a battery in an unsecured generic box.
Best For
Auxiliary-power builds running fridges, lighting or camp equipment.
Vehicles needing a defined battery mounting position.
Replacing or completing an ARB battery installation.
Battery Position, Charging And Cable Protection
Plan the battery around chemistry, capacity, charger type, ventilation requirements and cable length. Secure mounting is essential, and the positive cable needs protection close to the energy source. Account for heat, water exposure, service access and the current drawn by connected equipment.
