Thin, Tough And Australian Made — The Custom Lithium 100Ah NextGen Ultra Slim
The NextGen Ultra Slim takes everything that made the original work and hardens it. At 57mm thick it still disappears behind seats, under false floors and flat against canopy walls, but the case, mounting and internals are all built for the kind of treatment Australian touring hands out. 180 amps continuous discharge runs an induction cooker, fridge, tools or Starlink without complaint. 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 100Ah NextGen Ultra Slim Lithium Battery May Be Right For You:
- At 57mm thin it fits seamlessly into tight spaces in caravans, 4x4s and boats where a conventional battery is simply the wrong shape.
- 180 amps continuous discharge with up to 1000 amp peak protection, so slim doesn't cost you capability.
- Power an induction cooker, fridge, tools, Starlink, a 240V inverter and lights wherever your adventures take you.
- Built with premium, A-grade automotive cells, with a Heltech BMS and active balancer guarding against overheating and over-discharge.
- Certified Australian Made, built in Brisbane and individually bench-tested before it ships.
- Mounting it flat frees up the cubic space a conventional battery box would have taken from your build.

Custom Lithium 100Ah 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.
