The KickAss 12V 230Ah Lithium Battery delivers huge power in a compact, advanced design. With 230Ah of useable energy, 4000+ cycles at 80% DoD, Bluetooth monitoring, and support for series or parallel setups, it’s perfect for serious off-grid use. Link up to four for over 900Ah, with a built-in BMS for safety.

The ultra-compact design is ideal for those who have minimal space but need maximum power. Despite being only slightly larger than a standard N70 battery, it delivers double the usable capacity – perfect for tight spots & tricky installations. This KickAss battery delivers big power in a small package.
No more guesswork – stay in control of your power system by using the supporting Bluetooth app. Monitor critical battery parameters such as SoC, level, voltage, current, temperature, and real-time system alerts right from your smartphone. Having real-time data at your fingertips ensures optimal performance and peace of mind during all your off-grid adventures.
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.
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.
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.
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.
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.
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.
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.
