KickAss 12V 460Ah Ultra-X Lithium Battery Bundle with 3kW PowerBoss, BT Remote Module, Connections Kit & Wiring Kit

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.

Building on the all-in-one design of the 2kW PowerBoss, the KickAss 3kW PowerBoss delivers more power for demanding off-grid setups. It combines a 3000W pure sine wave inverter, 150A AC-DC charger, 50A DC-DC MPPT charger and DC load monitoring in one compact unit, making it ideal for 4WDs, caravans, camper trailers and canopies.

The 3000W pure sine wave inverter provides the capacity to run more demanding AC appliances and equipment away from mains power. When it’s time to recharge, the PowerBoss offers up to 150A charging from AC mains power, 50A from your alternator and 40A from solar. It also supports simultaneous AC and solar charging to help you make the most of available charging sources.

Measuring just 285 x 138 x 430mm, the 3kW PowerBoss is only slightly larger than the 2kW model, despite its increased inverter and charging capacity. Combining your inverter, chargers, monitoring and power management in one unit reduces the number of separate components taking up valuable space in your setup.

Bluetooth connectivity provides access to real-time system information, while compatible remote monitoring options offer flexibility in how you monitor your setup. Integrated DC load monitoring shows where your 12V power is going. Integration with compatible KickAss Smart and Ultra-X lithium batteries and the KickAss Bluetooth Smart Shunt provides accurate battery State of Charge information for greater visibility across your power system.

Designed for straightforward installation, the PowerBoss features plug-and-play connections, integrated AC circuit protection and compatibility with both 12V and 24V alternators. For larger builds that need more power, the KickAss 3kW PowerBoss delivers increased capability while retaining the compact design and simplicity of an all-in-one system.

Connect your alternator and DC-DC charger with the KickAss DC-DC to Alternator Wiring Kit – 4AWG (6.5m). Designed for fixed and variable voltage alternators, this heavy-duty kit is compatible with the KickAss 60A DC-DC Charger, 3kW PowerBoss and 50A DC-DC chargers. The 6.5m cable features a 4AWG tinned copper conductor for high-current charging and excellent corrosion resistance. Flexible silicone insulation makes routing easier, while a PET braided sheath provides added protection.

The kit includes a 100A MIDI fuse, ignition cable and a selection of fuse taps, including MIDI, Micro and Micro2 types, for connecting to your vehicle's ignition signal when required. Spare ring terminals and a replacement 100A fuse are also included. Whether you're installing a new dual battery system or upgrading an existing off-grid setup, this kit brings together the essential components for connecting your vehicle's alternator to your DC-DC charger.

Connect your KickAss 3kW PowerBoss with the KickAss PowerBoss Connection Kit – 95mm². This kit brings together the essential cables, connectors and tools for installation, including heavy-duty 95mm² tinned copper battery cables for excellent corrosion resistance. Flexible silicone insulation makes the cables easier to route through your setup, while a secondary PET braided sheath provides added protection.

A high-current quick-connect isolation connector allows you to disconnect your PowerBoss when needed. Dedicated solar input and DC load connection cables simplify the integration of solar panels and 12V accessories, while the included chassis ground cable and hand tools help you make secure connections. Whether you're building a new off-grid power system or upgrading an existing setup, this kit brings the essential connection components together in one package.

The Bluetooth Module for PowerBoss enables seamless communication with your PowerBoss device from your mobile device. Designed for plug-and-play installation, it connects easily via the supplied RJ45 connector - no additional setup needed. Featuring an integrated hardware switch, the module allows you to conveniently power the system on and off.
