Ultimate off-grid power with 300Ah lithium battery, 2000W inverter, DCDC charger & wiring for seamless energy management.
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.
Power cooktops, power tools, BBQs and more!
Please note: The inverter does not include battery cables. Suitable cables must be purchased separately to ensure safe and correct installation.
KickAss 12V to 240V Pure Sine Wave 2000W Inverter Feature Overview
2000W Continuous Output
Plenty of power to run all your AC essentials while on the move—induction cooktops, coffee machines, battery chargers for your power tools, and more.
Pure Sine Waveform
Delivers a clean and reliable sine wave output that replicates the AC signal from a home power point. Unlike modified sine wave inverters, the KickAss Pure Sine Wave Inverter is ideal for running sensitive electronics such as laptops, Starlink systems, and CPAP machines.
AC Automatic Transfer Switch
Simplify your off-grid setup with the integrated Automatic Transfer Switch. Power your AC devices from your battery bank, then seamlessly switch to mains power by plugging in the AC input cable. If mains power drops out, the inverter automatically switches back to battery power without interruption.
Multiple Protective Features
Multi-level safety protection uses both software and hardware safeguards to protect you, your inverter, and your devices. The system continuously monitors operation and automatically enters protection mode if necessary. Integrated Residual Current Devices (RCD) and Circuit Breakers (CB) provide added hardware protection, making it suitable for commercial and domestic use.
Optional Remote Control Display (Not Included in Base Version)
Enhance your setup with the optional remote display, allowing you to monitor and manage power usage remotely. The flush-mountable screen is low-profile and ideal for installation near your camp kitchen. It includes an integrated on/off switch for conserving battery power when the inverter is not in use.
Note: Only compatible with the blue KickAss remote inverter screen.
This 3-pin Anderson-style connector with built-in ignition wire makes connecting your 12V dual battery system easy. Perfect for wiring DC/DC chargers, battery boxes & auxiliary batteries.

KickAss Pure Sine Wave Inverter Remote Display Panel Feature Overview
Real-Time Monitoring
Unexpected power fluctuations can damage your equipment and waste valuable energy. With real-time monitoring, you can track your energy generation and power usage, spotting any problems early. This keeps your setup running smoothly and efficiently at all times.
Remote Control
Monitor and manage your power consumption from a distance—for example, from the front seat while your inverter is installed in the back of your truck. The included 3-metre cable allows you to access and control your inverter system easily.
Fault Diagnostics
When a system malfunction occurs, diagnosing the problem can be challenging and time-consuming. The KickAss Inverter Remote Display automatically identifies and reports inverter faults, providing detailed diagnostics to simplify troubleshooting.
Intuitive User Interface
