Features & benefits

• 460Ah Useable Capacity – Serious Off-Grid Power
  A huge 460Ah capacity gives you the freedom to pair with a 3000W inverter to run power-hungry gear like air conditioners and induction cooktops, all at once. Perfect for caravans and large setups, it lets you stay off-grid longer without relying on constant charging.
• 300A Continuous Discharge
  The 300A BMS delivers strong, stable output that can run a 3000W inverter while still leaving headroom for additional 12V appliances. With a surge capacity of up to 660A for 30 seconds, it easily handles startup surges and high inrush load demands.
• Install Horizontally or Vertically – Maximise Power In Tight Spaces
  Designed to fit where space is tight, the 460Ah Ultra-X battery can be installed lying flat in a locker or cabinet, and when you need more capacity, simply stack up to 4 batteries on top of one another! A linking kit is included, with busbars for parallel connection and mounting brackets to lock them together securely.
• Intelligent BMS
  The intelligent BMS provides multi-level protection across temperature extremes, overcharge, over-discharge, and short circuits. Key internal components are continuously monitored, so the battery stays safe and operating at its best – no matter the conditions.
• Bluetooth Monitoring
  No more guesswork – stay in control of your power system using the supporting Bluetooth app. Monitor crucial battery parameters such as SoC, wattage, voltage, current, temperature and real-time system alerts, right from your smartphone. Having real-time data at your fingertips ensures you’ll get optimal performance and peace of mind during all your off-grid adventures.
• Remote Display Monitoring
  These Ultra-X batteries pair seamlessly with the KickAss Smart Lithium Battery Remote Display Unit (sold separately), allowing you to keep an eye on your power usage from the comfort of your vehicle’s cabin – or anywhere you choose to install the RDU. As well as battery levels, the RDU monitors temperature, current, time to full/empty, voltage and more, meaning you’ll always have clear data at your fingertips.
• Parallel & Series Configuration
  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, giving you the flexibility to scale your setup exactly the way you need it.
• Parallel & Series Monitoring from BlueTooth App & Remote Display
  Monitoring multiple batteries in a series or parallel setup usually requires an external shunt, but these batteries eliminate that need. Simply connect each Ultra-X series battery using an RJ45 cable, and the optional KickAss Remote Display Unit (RDU) will seamlessly interface with the entire battery bank. This allows you to track the performance of all connected batteries as a single unit, delivering consolidated data without the hassle of external shunts. Alternatively, use the supporting Bluetooth app to monitor the entire system’s performance without the need for any additional hardware.
• 4000 + Cycles at 80% DoD
  Designed for longevity, this battery offers over 4000 charge and discharge cycles at 80% Depth of Discharge (DoD) and a 0.5C charge/discharge rate. This means that even with regular use, the battery is built to last for years, delivering consistent performance without a significant drop in capacity. Whether you’re powering your gear daily or just taking occasional trips, the durability and long cycle life of this battery ensures you get maximum value, making it a smart investment for anyone seeking long-term performance.
• Rugged Design: Metal Case with Integrated Mounting Points & Anti-Vibration Pads
  The battery installation is super simple as the housing is complete with integrated mounting points with anti-vibration pads, meaning you won’t have to worry about sourcing or installing a separate battery tray.
• Brackets Included for Vertical Mounting
  Prefer to mount your battery vertically? The Ultra-X 460Ah includes heavy-duty mounting brackets, allowing you to securely install it against the wall of your canopy, caravan, motorhome, or any other setup where a vertical installation makes the most sense.
• IEC 62619 Certification
  The battery is IEC62619 certified, providing peace of mind that it meets stringent safety standards.
• 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.
