KickAss Twin 12V 230Ah Ultra-X Lithium Slimline Kit with 3kW PowerBoss, BT Remote Module, Connections Kit, Wiring Kit & Linking Cables

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.

Having real-time data at your fingertips ensures optimal performance and peace of mind during all your off-grid adventures.

BMS with Multiple Safety Features

The KickAss 12V 230Ah Deep Cycle Lithium Battery is equipped with an advanced Battery Management System (BMS) that ensures safety and reliability. The BMS actively monitors and protects the battery from common issues such as overcharging, over-discharging, short circuits, and overheating, ensuring safe operation at all times.

Create a Battery Bank with Over 900Ah of Usable Capacity

These batteries support parallel and series configurations for maximum versatility. Link up to four in parallel to create a massive battery bank with over 900Ah of usable capacity, delivering serious power for extended off-grid use. This capability allows you to tailor your power setup to your exact needs.

Monitor Your Battery Bank Remotely

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. Alternatively, use the supporting Bluetooth app for system monitoring without additional hardware.

230Ah Usable Capacity

With 230Ah of usable capacity, the KickAss 12V Deep Cycle Lithium Battery offers an abundance of power for extended off-grid adventures. This large capacity means you can run devices and appliances for longer periods without frequent recharges.

230A Continuous Charge & Discharge with 460A Pulse Capacity

This battery delivers exceptional performance with its 230A continuous charge and discharge capability, ensuring a steady and reliable flow of power for demanding applications. The impressive 460A pulse capacity allows it to handle sudden power surges, making it incredibly versatile.

4000+ Cycles @ 80% DoD 0.5C

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 durability ensures a long-lasting, high-performance battery for years to come.

Metal Case with Integrated Mounting Points

The durable metal housing with integrated mounting points eliminates the need for a separate battery tray. The heavy-duty metal casing not only protects the battery from the elements and rough conditions but also makes installation easier and more secure.
