Nearly A Week Off-Grid, 85mm Thick — The Custom Lithium 280Ah NextGen Ultra Slim
At 280 amp hours you stop planning around your power. Air conditioning in short bursts, an induction cooktop, a coffee machine, two fridges and Starlink become things you simply use. The remarkable part is that it's still only 85mm thick — it mounts flat behind seats or under a floor, giving you back the cubic space a conventional battery of this capacity would have swallowed. 330 amps of continuous discharge, M10 terminals, Heltech BMS with active balancer, built in Brisbane.
Maximum capacity, minimum footprint. Order yours today!
Why The Custom Lithium 280Ah NextGen Ultra Slim Lithium Battery May Be Right For You:
- Stay out for the better part of a week running everything you own, because 280Ah takes the question of whether you've got enough power off the table entirely.
- Get that capacity without surrendering a cupboard to it — at just 85mm thick it mounts flat in dead space, where a conventional battery this size would need a box of its own.
- Run the induction cooktop and the inverter at the same time without the BMS backing off, thanks to 330 amps of continuous discharge and up to 1600 amps of peak protection.
- Make a proper connection for the heavy cable a system this size 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.
- 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 280Ah 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.
