400Ah Lithium Battery 12V Waterproof Bluetooth Chassis Mount (IP67)
Description
400AH OF CERTIFIED LITHIUM POWER - FOR TOURERS WHO REFUSE TO COMPROMISE
For serious off-grid touring, the AllSpark 400Ah 12V is the chassis mount battery box built to go the distance. IP67 rated, IEC 62619 certified as a complete battery, and designed around new 2025-generation premium A-Grade prismatic cells, this 400Ah lithium battery delivers the capacity and peak current output that extended trips demand.
Engineered in Australia by Offroad Living, the powder-coated stainless steel housing mounts directly to your chassis rail - sitting above the frame's lowest point to preserve your full ground clearance on corrugated outback tracks and creek crossings. Bluetooth monitoring is fully integrated into the BMS, so you get precise cell-level data from your phone at no extra cost.
Whether you're running multiple appliances, extended off-grid stints, or a motorhome electrical system, the 400Ah gives you the headroom to do it without rationing power.
