Thirty More Amp Hours, Same Install — The Custom Lithium 230Ah Slim
The 230Ah Slim sits in exactly the same case as the 200Ah — same 450 x 125 x 252mm footprint, same 18 kg, same mounting — and carries 30 more amp hours. For most touring setups that's another day before you need to recharge, and it costs $100. If the 200Ah Slim already suits your space, this is the one to take.
Same slot in your build, more time off-grid. Order yours today!

Why The Custom Lithium 230Ah Slim Lithium Battery May Be Right For You:
- Identical 450 x 125 x 252mm case and 18 kg weight as the 200Ah — the extra capacity costs you nothing in space or payload.
- At 125mm wide it fits the narrow cavities in canopies, caravans and 4x4 builds that a conventional battery can't reach.
- 200 amps continuous discharge with 1000 amp peak protection, so a fridge, inverter, water pump and lights run together.
- Takes up to 100 amps of charge, so a decent DC-DC charger refills it properly on a single drive 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.
