Limited Edition Matte Black Design
This exclusive Black Edition takes our proven Ultra-X Slim battery and gives it a bold, premium look. Built for performance and style, it’s finished in a sleek matte black coating that stands out in any setup — whether it’s in a high-end canopy build or a custom 12V fit-out.
Ultra Compact, Slimline Power
Measuring only 500mm x 510mm x 70mm, the Ultra-X Slim Black Edition delivers massive power in a compact form. Perfect for tight installs behind seats, under false floors, or in canopies, it’s the ultimate space-saving powerhouse for serious off-grid adventurers.
Smart Bluetooth App Monitoring
Get real-time insight into your battery’s performance using the Bluetooth app. Track your State of Charge, voltage, current, temperature, and system alerts straight from your phone — giving you complete control over your setup, wherever you are.
Advanced BMS for Complete Protection
Equipped with a high-performance Battery Management System (BMS), this battery safeguards against overcharge, over-discharge, short circuits, and overheating. The BMS ensures stable, efficient, and reliable power delivery no matter how tough the conditions.
Expand Your Power — Parallel or Series Ready
Need more power? Connect multiple Ultra-X Black Edition batteries in parallel or series to create a massive battery bank — up to 900Ah of usable capacity. Ideal for powering caravans, canopies, 4WDs, and off-grid systems for extended adventures.
Monitor Remotely with Ease
Forget complex wiring — simply connect your batteries with an RJ45 cable for seamless integration with the KickAss Remote Display Unit (RDU). You can also monitor everything via the Bluetooth app, no external shunt required.
Engineered for Endurance
Delivering over 4000+ cycles at 80% Depth of Discharge (DoD) and a 0.5C rate, the Ultra-X Slim Black Edition is built to last. With 230A continuous charge/discharge and a 460A pulse capacity, it powers even the most demanding 12V setups.
Durable Metal Case with Integrated Mounting Points
The heavy-duty metal casing provides maximum protection while simplifying installation. Integrated mounting points make for a secure, professional finish — and the matte black exterior adds a touch of rugged sophistication.

Very easy to mount, very easy to install.
Using the bluetooth app, i can read the battery temp, charge/discharge amps and the no. of cycles the battery has done. Can also see the health of the battery, and each individual cells. I can see also the ability to add additional batteries and link together, however at this stage i only have the one. I may look into adding a second down the track
