Everything that is included in this KickAss kit!
At just 65mm thick, the KickAss Ultra-X 120Ah Slimline Lithium Battery is the slimmest 120Ah lithium battery on the market, packing 1536Wh of power into a design that fits behind vehicle seats and into tight spaces. With Bluetooth monitoring, 120A continuous charge and discharge, 4000+ cycles, an advanced BMS and a 7-year warranty, it's built for serious off-grid adventures.
The KickAss Smart 12V 120Ah Ultra-X Lithium Slimline Deep Cycle Battery delivers serious off-grid power in an exceptionally compact design. At just 65mm thick, it's the slimmest 120Ah lithium battery on the market, designed to fit into spaces where conventional deep cycle batteries simply won't. Tuck it behind vehicle seats, inside canopies or along ute tub walls, leaving more room for all your other gear. It's an ideal solution for 4WDs, caravans, camper trailers and off-grid touring setups where every millimetre counts.
Despite its slim profile, this battery delivers impressive power and performance. With 120Ah of usable capacity and 1536Wh of stored energy, this ultra-compact LiFePO4 battery has plenty of power to keep your camping fridge, lights, fans and other 12V essentials running. It also supports continuous charging and discharging at up to 120A, making it a capable choice for more demanding off-grid power systems. Premium A-grade prismatic LiFePO4 cells deliver consistent performance, with over 4000 cycles at 80% depth of discharge for years of reliable use.
Keeping track of your power is easy thanks to integrated Bluetooth connectivity. Simply connect to the KickAss app on your smartphone to monitor your battery's state of charge, voltage, current and temperature, or use a compatible remote monitoring screen for convenient access to your battery information. An advanced intelligent Battery Management System (BMS) works in the background to protect against overcharging, over-discharging, short circuits and excessive temperatures, while a low-voltage protection override switch provides an additional recovery option if your battery shuts down.
Installation is just as flexible as the battery itself. Mount it flat, upright or on its side to suit your available space, and take advantage of parallel and series configuration support for compatible multi-battery setups. With an IP65 dust and water resistance rating, support for AS/NZS 3001.2 compliant installations and a generous 7-year warranty, the KickAss Ultra-X 120Ah Slimline Lithium Battery proves that you don't need to sacrifice valuable space to enjoy serious off-grid power.
