KickAss 460Ah Ultra-X Lithium Complete Dual Battery Kit with 3000W Inverter, 50A AC/DC Charger & 40A DCDC Charger

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.

Designed for total flexibility, this charger supports Lead Acid, AGM, Gel, Calcium, and Lithium batteries. It automatically applies the correct charging profile for each chemistry, ensuring the right balance of speed, safety, and battery protection.

Integrated Vehicle Diagnostics

Doubles as a diagnostic tool, checking alternator output, starter battery health, and cranking performance. Instantly identify weak points in your vehicle’s electrical system before they become roadside problems.

Dynamic Battery Maintenance

Once your battery reaches full charge, the charger switches to intelligent maintenance mode, monitoring voltage and applying a top-up only when needed. This prevents overcharging and keeps your system fully charged and ready.

Advanced Multi-Stage Charging

The smart 3-stage algorithm – bulk, absorption, and float – ensures fast, safe, and complete charging. Throughout the process, voltage and current are constantly monitored to deliver precision control, maximise efficiency, and extend battery life.

Intelligent Cooling & Quiet Mode

Temperature-controlled fans automatically adjust speed for efficient cooling with minimal noise. Activate Quiet Mode to further reduce fan operation and output current – ideal for overnight use or low-noise environments.

Simple Plug & Play Setup

With Anderson-style DC output and IEC AC input, installation is fast and flexible. Use the supplied Anderson-to-ring terminal cable for fixed installs or optional alligator clips for portable use, giving you connection options for any charging scenario.

Lithium Recovery & Starter Battery Replacement Mode

Includes a recovery function to safely revive lithium batteries that have entered low-voltage protection mode. It also operates as a regulated 12V DC power supply, for maintaining system voltage during battery replacement to avoid ECU resets or data loss.

EV and Hybrid Inverter Enabled Dual Battery Charger

Utilise the inverter in your EV, Hybrid or mild hybrid vehicle to charge our dual battery system through the 50A Smart AC Charger. Simply connect the charger input to the inverter output in the vehicle and you’ve got a plug-and-play dual battery system.

Clear LCD Display & Status Indicators

Stay informed with the integrated LCD screen, showing live voltage, current, and charge stage data. A status LED provides at-a-glance confirmation of charger operation and progress.

Built-In Protection & AGM Reconditioning

The Charge Guard system includes reverse polarity, short circuit, over-voltage, over-temperature, and over-current protection to safeguard your gear. Plus, an AGM Recondition Mode helps restore ageing AGM batteries by dissolving sulphate buildup and recovering lost capacity.

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.

Bluetooth Monitoring & App Control

Connect your charger to your smartphone via Bluetooth to monitor performance in real time. The KickAss App gives you complete visibility over charging status, voltages, current flow, and system alerts – all from your pocket.

Simple Plug & Play Installation

Thanks to Anderson-style connectors, installation is quick and hassle-free with no complex wiring required. It’s designed for DIY setups and easy integration into your existing system.

Dual Input: Alternator & Solar Charging

Charge from your vehicle’s alternator while driving or connect a solar panel when stationary – this charger handles both. Its built-in MPPT solar regulator ensures maximum efficiency when using solar input.

Built for Aussie Conditions

Rated IP66, the KickAss 40A DCDC Charger is waterproof, dustproof, and rugged enough to handle corrugated tracks, extreme heat, and remote adventures. It’s built tough for Australian conditions.

The KickAss Ultra-X 460Ah Deep Cycle Lithium Battery is built for exactly that, delivering massive useable capacity, intelligent protection, and the flexibility to scale your system as your needs grow.

460Ah of Useable Capacity, Run Everything, Go Anywhere

At the heart of the Ultra-X is a huge 460Ah of useable capacity, giving you the freedom to run high-draw appliances like air conditioners and induction cooktops simultaneously, without constantly watching your power levels. Whether you're parked up for a week in the outback or running a fully loaded caravan, this battery has the grunt to keep everything running exactly the way you want it.

300A Continuous Discharge, Stable, High-Output Power

The Ultra-X delivers strong, consistent 300A output capable of running a 3000W inverter while still leaving headroom for additional 12V appliances. With a surge capacity of up to 660A for 30 seconds, it handles the demands of multiple high current devices starting simultaneously.

Stackable Design, Maximum Capacity, Minimum Space

Space is always at a premium in a caravan or camper build, and the Ultra-X is designed with that in mind. It is specifically designed to be installed lying down flat in a locker or cabinet to make the most of tight spaces. When you need more capacity, simply stack multiple units together. A linking kit is included, complete with busbars for parallel connection and mounting brackets to lock the batteries together securely.

Intelligent BMS, Built-In Protection You Can Count On

The Ultra-X features an intelligent multi-level BMS that continuously monitors key internal components to keep the battery operating safely under all conditions. Protection covers temperature extremes, overcharge, over-discharge, and short circuits, so whether you're in the middle of a scorching summer or a frosty alpine night, the battery manages itself so you don't have to.
