Boost your off-grid adventures with the ultimate power bundle featuring a 300Ah Lithium battery, 2200W inverter, and 40A DCDC charger.
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.
This 2200W pure sine wave inverter-charger delivers clean, stable power for your everyday appliances, and rapidly charges your battery from shore power via 1800W AC ultra-fast charging. Bluetooth monitoring, plug-and-play install, built-in safety protection, and support for multiple battery chemistries make it a smart, space-saving upgrade for any setup.
The KickAss 2200W Bi-Directional Inverter-Charger delivers mains-quality power in a compact, all-in-one unit. Combining a 2200W pure sine wave inverter with an 1800W AC ultra-fast charger, it provides both AC power and battery charging without the need for separate devices, additional wiring or extra installation space.
The 2200W pure sine wave inverter converts 12V DC battery power into clean, stable 230V AC power, making it suitable for everyday appliances, sensitive electronics and motor-driven equipment. When connected to shore power, the built-in 1800W AC charger provides up to 135A of charging current.
Bluetooth monitoring and control via the KA Charge app allows you to select battery chemistry, choose a charging mode, switch the unit on or off and view up to 32 hours of performance history. An optional remote switch with OLED display and LED indicators provides additional control and system status monitoring.
Dynamic power adjustment technology prioritises available power to connected AC equipment, helping maintain operation when the incoming power supply fluctuates.
Plug-and-play AC connectivity includes an IEC input and two AC outlets, eliminating the need for hardwiring. Built-in RCBO protection provides overload and earth leakage protection, while intelligent variable-speed cooling fans help regulate operating temperature and minimise unnecessary fan noise.
The compact slimline design is suited to space-limited vehicle and off-grid installations. The unit supports LiFePO4, AGM, CAL and GEL battery chemistries and also includes a USB-A output for charging compatible phones, tablets and other devices.
Charge your dual battery system fast with this 40A DCDC Charger. Ideal for lithium & lead acid batteries, it suits medium to large setups. Solar MPPT, Bluetooth, lithium wakeup, and multi-stage charging – all in a tough, IP66-rated, plug & play unit built for Aussie conditions. Note this charger requires the KickAss Heavy Duty Wiring Kit or 6AWG cable from the starter battery.
Powerful 40A Dual Battery Charging
With a high 40A output, this charger is perfect for keeping larger lithium and lead acid battery systems topped up and ready for action. It ensures fast, safe charging for demanding off-road or touring applications.

Adjustable Max Input Current – Hybrid Compatible
The maximum input current can be configured via the Bluetooth app, allowing the charger to limit the draw from your vehicle’s alternator, without reducing the maximum charge current when charging from solar. This makes it ideal for some hybrid vehicles or those with low-output alternators, helping prevent overload and ensuring stable, efficient charging without placing strain on your electrical system.
Smart Alternator Ready
Modern vehicles with smart alternators are no problem. The unit supports both smart and fixed-voltage alternators and includes an ignition trigger wire to start or stop charging based on engine status.
Lithium Battery Compatible
Fully lithium-ready, this charger includes an automatic lithium wakeup function that can safely restore LiFePO4 batteries from low voltage protection or sleep mode – no manual intervention needed.
Advanced Multi-Stage Charging
Precision charging algorithms help extend the life of your auxiliary battery. The charger delivers multi-stage charging tailored to the battery type, helping maintain peak performance over the long haul.
Starter Battery Isolation
To protect your starting battery, the charger only delivers current to your auxiliary battery when the engine is running, and automatically disconnects when the vehicle is off – eliminating unwanted drain.
Supports Multiple Battery Chemistries
Whether you’re using lithium, AGM, wet, gel, or calcium batteries, this charger has you covered. It’s a versatile solution designed to support a wide range of battery types.
Perfect for 4WDs, caravans, camper trailers, and off-grid touring setups, the KickAss 40A DCDC Charger with Solar MPPT and Bluetooth delivers intelligent charging for serious adventurers.
