230Ah At 71mm, Built Tough — The Custom Lithium 230Ah NextGen Ultra Slim
Long-stay capacity in a shape that mounts flat. The 230Ah NextGen Ultra Slim is 71mm thick, so it sits behind seats, under a false floor or against a canopy wall and gives you back the cubic space a conventional battery box would have eaten. 330 amps of continuous discharge and M10 terminals handle an induction cooker, inverter, fridge and Starlink without flinching. Premium A-grade automotive cells, Heltech BMS with active balancer, built in Brisbane.
Unparalleled performance in the space you've got. Order yours today!
Why The Custom Lithium 230Ah NextGen Ultra Slim Lithium Battery May Be Right For You:
- Reclaim the entire cubic space a battery box would have stolen from your build, because at 71mm thick this one mounts flat behind the seats or under a false floor — days of capacity from somewhere you'd already written off.
- Push it as hard as you like without the BMS backing off, thanks to 330 amps of continuous discharge and up to 1600 amps of peak protection soaking up inverter surge loads.
- Make a proper connection for the heavy cable this capacity deserves, because it runs M10 terminals rather than M8 — less resistance, less heat, nothing working loose on the road.
- Trust what's inside it and stop thinking about it, with premium A-grade automotive cells and a Heltech BMS with active balancer watching for overheating and over-discharge.
- Top it back up properly every day on a 100 amp charge rate, so your solar and DC-DC charger put real capacity back in rather than nibbling at it.
- Buy something built down the road rather than shipped across an ocean — certified Australian Made in Brisbane and bench-tested individually before it ships.
Custom Lithium 230Ah NextGen Ultra Slim Lithium Battery Installation:
When installing the NextGen Ultra Slim along the base of a canopy or similar surface, we recommend not using the bottom mounting rail. This lets the vehicle or canopy floor carry the weight of the battery, reducing stress on the mounting system and improving long-term stability.
If you are unsure about installation, please contact us on 1300 902 361 for assistance, or alternatively please reach out for us to organise an installation.
*Improper installation will void your warranty and may result in injury.
