Real Capacity In A Narrow Case — The Custom Lithium 200Ah Slim
The usual trade-off with a slimline battery is capacity: you get the shape you need and give up the amp hours. The 200Ah Slim doesn't ask you to. At 125mm wide it still slides into canopy walls, under false floors and behind seats, but it carries enough to run a fridge, lights, a water pump and a 240V inverter for days off-grid. 200 amps of continuous discharge, A-grade automotive LiFePO4 cells, built right here in Australia.
The shape you need, the capacity you wanted. Order yours today!

Why The Custom Lithium 200Ah Slim Lithium Battery May Be Right For You:
- At 125mm wide it fits the narrow cavities in canopies, caravans and 4x4 builds that a conventional 200Ah battery can't reach.
- 200 amps continuous discharge with 1000 amp peak protection — enough for a fridge, inverter, water pump and lighting together.
- 200Ah covers several days off-grid for most touring setups before recharging becomes a consideration.
- Takes up to 100 amps of charge, so a decent DC-DC charger refills it properly on a single leg between camps.
- A-grade automotive LiFePO4 cells with BMS protection and vibration-insulated components for corrugated roads.
- You're supporting the local economy. All Custom Lithium batteries are made here in Australia and individually bench-tested.
