The AllSpark AS-40012LICMBT is a heavy-duty 400Ah 12V LiFePO4 lithium deep-cycle battery engineered for permanent chassis-mount installations in caravans, motorhomes, camper trailers, and 4WD builds. Rated IP67 waterproof and dustproof, it can withstand full immersion to 1 metre for 30 minutes, making it ideal for underbody mounting in Australian conditions where creek crossings, corrugated dirt roads, and torrential downpours are part of the journey. An integrated Bluetooth-enabled Battery Management System (BMS) lets you monitor state of charge, voltage, current draw, cell balance, and temperature in real time from your smartphone — no extra shunt or monitor wiring required. With a usable capacity of up to 100% depth of discharge and a cycle life exceeding 3,000 charge cycles at 80% DoD, this battery delivers significantly more usable energy and a far longer service life than equivalent AGM alternatives.

Designed specifically for serious Australian caravan and 4WD adventurers who demand reliable off-grid power without compromise, the AllSpark 400Ah chassis-mount battery suits high-draw setups including dual-compressor fridge/freezer systems, inverters, CPAP machines, lighting, and satellite communication devices. Whether you're lap-of-Australia touring, remote outback camping, or parked up on a long-haul station run, the battery's robust steel chassis-mount housing absorbs vibration and road shock, while its low self-discharge rate means power is ready when you need it most. Compatible with leading DC-DC chargers and MPPT solar regulators, this battery integrates seamlessly into any 12V power system for worry-free off-grid living across Australia's most demanding terrain.
