A 48V caravan system delivers advantages that lower voltage setups simply can't match - higher inverter efficiency, lower cable current draw, reduced power losses over longer runs, and the ability to run serious loads without the weight and complexity of parallel battery banks.
The AllSpark 100Ah 48V chassis mount is designed and developed in Australia by Offroad Living specifically for 48V caravans and motorhome builds that demand efficiency, compliance, and long-term reliability.
IP67 rated and IEC 62619 certified as a complete battery unit, it's built from powder-coated stainless steel and mounts above the chassis rail - preserving your ground clearance on corrugated tracks and creek crossings. Full Bluetooth monitoring is integrated into the BMS at no extra cost, giving you precise 48V caravan power data on your phone in real time.
If you're building or upgrading to a 48V system, the AllSpark 100Ah 48V is built for exactly that purpose.
Purpose-built 48V caravan power should not come at the cost of your ground clearance. The AllSpark 100Ah 48V chassis mount has in built mounting points, allowing for it to be installed securely above the frames lowest point - so the frame remains the lowest point, keeping your vehicle's original clearance for the tracks that make a 48V build worthwhile.
No hanging below the chassis. No compromise on capability.




IEC 62619 certification on the cells alone doesn't mean the complete battery is safe or compliant. AllSpark batteries are independently tested and certified as complete assembled units - cells, BMS, housing, workmanship - the lot.
For piece of mind and reliability - it's the stamp of approval you've been looking for.
Monitoring a 48V caravan power system accurately requires data from inside the BMS, not a shunt bolted on externally. AllSpark's integrated Bluetooth monitoring gives you individual cell voltages, state of charge, current in and out, cycle count, and full charge history - direct from the source.
This chassis mount battery comes fully enclosed in a tough stainless steel casing, meaning you also don't have to fork out for a flimsy caravan battery box, adding another $100+.
Included in the battery price, with no extra hardware required.




At 48V, a BMS failure isn't just an inconvenience - it can shut down your entire caravan system in a remote location.
The AllSpark BMS is engineered to give you piece of mind - protecting against high and low temperature (-20°C to +60°C), over-voltage, under-voltage, short circuit, reverse polarity, and over-current.
Automatic cell balancing maintains performance across the full 48V cell stack throughout the battery's life.
A 48V system's key advantage is the ability to deliver high power output at lower current draw, which means your inverter runs more efficiently and your cabling handles the load more effectively. The AllSpark 100Ah 48V delivers the output to run a 5000W inverter on a single battery - kettle, aircon, induction cooktop, and more, all at the same time.
With A-Grade prismatic cells rated to handle the peak demand without voltage sag, you can run your appliances with confidence.
