KickAss Triple 12V 300Ah Lithium Bundle with 3000W Inverter & 40A Charger - 900Ah Total Capacity

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.

KickAss 12V to 240V Pure Sine Wave 3000W Inverter Feature Overview

3000W 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 you get from a home power point. Unlike modified sine wave inverters that don't produce a true sine wave, the KickAss Pure Sine Wave Inverter is ideal for running sensitive electronic devices like laptops, Starlink, and CPAP machines.

AC Automatic Transfer Switch

Simplify your off-grid installation with the Automatic Transfer Switch. Power your AC devices from your batteries, then once you’re back on-grid, simply plug in the AC input cable to switch over to mains power. If the mains supply cuts out, the inverter will seamlessly switch back to battery power.

Multiple Protective Features

Multi-level safety protection utilises both software and hardware features to protect you, your inverter, and your devices. The inverter continuously monitors operation and will trigger protection mode if an unsafe condition is detected. Integrated Residual Current Devices (RCD) and Circuit Breakers (CB) provide additional hardware protection, making the inverter suitable for commercial environments.

Optional Remote Control Display (Not Included in Base Version)

The optional remote display allows you to monitor and manage power usage wherever needed. The low-profile screen is discreet and can be flush-mounted into any panel—for example, near your camp kitchen. The remote also features an integrated on/off switch to conserve battery power.

Note: Only compatible with the blue KickAss remote inverter screen.

Surge Power – Reaches 6000W in 2 Seconds

With a peak surge rating of 6000W for up to 2 seconds, this inverter is ideal for supporting devices with a high current draw, like power tool battery chargers, microwaves, and induction cooktops.

High 94% Conversion Efficiency

Inefficient inverters waste energy when converting DC to AC. The KickAss 3000W Pure Sine Wave Inverter achieves 94% efficiency, maximising the usable capacity of your battery bank.

Integrated USB Charging Ports

Includes an integrated 5V 2.1A USB port for convenient charging of your small devices directly from the inverter.

Smart Cooling System

The smart fans automatically adjust their speed to keep the inverter cool, increasing efficiency and maintaining optimal power output.

High Quality Circuitry Components

Built using premium quality components and the latest technology, this inverter delivers reliable performance. Even under heavy loads and peak surges up to 4000W, it remains protected against spikes and surges.

Multiple Mounting Options

Four convenient mounting points allow easy installation into your caravan, camper, or canopy 12V power setup.

Powerful 40A Dual Battery Charging

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.
