Built For Tight Spaces — The Custom Lithium 100Ah Slim
Canopies, under-seat cavities and caravan lockers all have the same problem: plenty of length, not much width. A standard battery won't go in, and a tray eats what room is left. The 100Ah Slim solves it at 112mm wide — it slides into gaps a conventional battery can't reach, while still giving you 180 amps of continuous discharge to run your 12V accessories and a 240V inverter. At 11 kg it's one of the lightest ways into lithium, and it's built right here in Australia.

Why The Custom Lithium 100Ah Slim Lithium Battery May Be Right For You:
- At just 112mm wide it fits behind seats, inside canopy walls and under false floors where a conventional battery simply won't go.
- 180 amps continuous discharge with 1000 amp peak protection — enough for a fridge, lights, a water pump and a 240V inverter at the same time.
- 11 kg means one person can lift it into position without help, and it adds far less weight to your build than lead acid.
- Great for 4x4s, caravans and canopies, powering Starlink, induction cookers, air compressors, computers, cameras and lights.
- A-grade automotive LiFePO4 cells with BMS protection, all components insulated against vibration so corrugations don't shake it apart.
- You're supporting the local economy. All Custom Lithium batteries are made here in Australia and individually bench-tested.
