Power up your adventure with 600Ah of reliable off-grid energy using this twin lithium battery bundle and linking cable setup.
Everything that is included in this KickAss kit!
The first release in the new Series 2 Ultra-X battery range, this 300Ah lithium power house packs 300Ah of usable capacity into a compact design that can be installed anywhere from under beds in caravans to the back of ute tubs. Connect up to four in parallel or series & monitor the entire battery bank remotely via Bluetooth – no external shunt required. Supports AS/NZS:3001 compliance.
The KickAss Smart 12V 300Ah Ultra-X Lithium Compact Deep Cycle Battery LiFePO4 is the first battery in the second series of our premium Ultra-X range, building on everything customers already love. This second series introduces a new look along with key upgrades including an IP65-rated enclosure, integrated Low Voltage Recovery (LVR) button, and supports AS/NZS 3001.2 compliant installations. It's the next evolution of KickAss Ultra-X Lithium Batteries, delivering the same premium performance with even more capability.
With 300Ah of usable capacity and a 300A continuous discharge, it's built to power demanding off-grid setups, making it the ideal battery to pair with a 3000W inverter for running fridges, induction cooktops, coffee machines, power tools, lighting and other 12V and 240V appliances at the same time. This high-performance 12V lithium battery gives you more power without taking up valuable space.
Its compact form factor opens up installation options that simply aren't possible with many large-capacity batteries. Mount it neatly beneath caravan beds or bench seats, inside ute tubs under roller covers, within canopies or in camper trailers. A built-in vent means that the battery supports AS/NZS 3001 compliant installations, while the rugged metal housing, IP65 rating and intelligent Battery Management System ensure reliable performance in harsh Australian conditions.
Bluetooth monitoring lets you check battery status, capacity, voltage, temperature and current directly from your smartphone, while the optional Remote Display provides the same information for those who prefer a dedicated screen. If you accidentally run your battery too flat, then the integrated Low Voltage Recovery (LVR) button makes it easy to reawaken the BMS after an over-discharge, helping you get back on the road with the touch of a button.
As your power needs grow, your battery system can grow with them. Connect up to four Ultra-X 300Ah lithium batteries in series or parallel to create a powerful battery bank, then monitor the entire system through the KickAss app or Remote Display without needing an external shunt. The KickAss Ultra-X 300Ah LiFePO4 Battery delivers a cleaner, simpler and smarter way to build a scalable off-grid power system.
These cables allow you to link batteries in series or parallel to create a battery bank and increase power capacity. 525mm, 12V, rated to 100amps.
525mm Length Pair (Black & Red) Battery Joiner Pack
