CUSTOMER REVIEWS
Outback Proof Tested
Super Compact and Great Value
Super compact battery and fantastic value for money. I paired two of these with other KickAss products to completely upgrade my 12V power system in the caravan. Highly recommended.
The X Factor in Battery Design
This battery brings the X factor in both design and capacity. KickAss has absolutely nailed the brief, this is genius-level engineering.
An Absolute Beast with Smart Features
Absolute beast of a battery. Took up half the space of my old Kings 200Ah. The communication ports for the display are a smart idea and make setup super easy. Powers my induction cooktop and dual fridges with ease.
Reliable Power and Monitoring for Hot Conditions
Awesome battery with great communication outputs to monitor all my gear. Powers my 95L fridge for days, even in the heat.
Compact, Robust, and Packed with Tech
Compact, easy to install, and built tough. The Bluetooth BMS is fantastic and even lets me monitor individual cell states.
Fantastic Size and a Great Upgrade
These batteries are a great size. I replaced two 100Ah units with two Ultra-X batteries, and they only took up a fraction more space.
