Custom Lithium 100Ah Ultra Slim Lithium Battery

55mm Thin — The Custom Lithium 100Ah Ultra Slim Goes Where Nothing Else Fits

Some builds have no room left at all. Behind the seats of a dual cab, inside a false floor, flat against a canopy wall — these are the spaces where every other battery is simply the wrong shape. At 55mm thick, the 100Ah Ultra Slim slides into them without compromising on power. You still get 180 amps of continuous discharge to run an induction cooker, tools, a fridge and Starlink. It just does it from somewhere you'd forgotten you had.

Why The Custom Lithium 100Ah Ultra Slim Lithium Battery May Be Right For You:

• Just 55mm thick — it fits behind seats, under false floors and in canopy walls where no conventional battery will go.
• 180 amps continuous discharge with up to 1000 amp peak protection, so thin doesn't mean underpowered.
• Power your induction cooker, tools, fridge, Starlink, 240V inverter, coffee machine and lights without rationing.
• Mounting it flat against a wall or under a floor frees up the cubic space a conventional battery box would have eaten.
• A-grade automotive LiFePO4 cells with BMS protection, and all components insulated against vibration for corrugated roads.
• You're supporting the local economy. All Custom Lithium batteries are made here in Australia and individually bench-tested.
