KickAss 12V 460Ah Ultra-X Compact Lithium Core Dual Battery Kit with 40A DCDC Charger, Remote Display & Wiring

When you're running a full caravan setup far from the nearest power point, you need a battery that won't let you down. 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.

Bluetooth Monitoring, Your Power System in Your Pocket

Stay on top of your power with the KickAss Bluetooth app. Monitor state of charge, wattage, voltage, current, temperature, and real-time system alerts, all from your smartphone. No more guesswork, no more surprises. Having live data at your fingertips means you can make smarter decisions about your power usage and get the most out of every charge cycle.

Remote Display Monitoring, At-a-Glance Power Data

The Ultra-X pairs seamlessly with the KickAss Smart Lithium Battery Remote Display Unit (sold separately), letting you monitor battery levels, temperature, current, time to full/empty, voltage and more from inside your vehicle's cabin or wherever you choose to mount it. Clear, real-time data, always within sight.

Parallel & Series Configuration, Scale Your Setup Your Way

The Ultra-X is built to grow with your power needs. Connect up to four batteries in parallel to build a 12V bank of up to 1840Ah, or wire them in series to create a 48V system at 460Ah. The Ultra-X gives you the flexibility to configure your system exactly the way you need it.

Whole-System Monitoring, No External Shunt Required

Monitoring a multi-battery setup usually means adding an external shunt to the equation, but not with the Ultra-X. Simply connect each battery using an RJ45 cable, and both the optional KickAss Remote Display Unit and the Bluetooth app can monitor the entire bank as a single unit. Consolidated data, no extra hardware, no hassle.

Built to Last, Rugged, Certified, and Ready for Anything

The Ultra-X is housed in a tough metal case with integrated mounting points and anti-vibration pads, making it equally at home in a hard-working caravan, 4WD, or off-grid setup. With a cycle life of 4000+ cycles at 80% depth of discharge and IEC 62619 certification confirming it meets stringent international safety standards, this is a battery engineered for the long haul.

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.

Compatible with 12V & 24V Alternators

Highly versatile, this charger is compatible with both 12V and 24V alternators, making it suitable for a wide range of vehicle types including trucks, commercial vehicles, and 4WDs.

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.

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.
