Ultra Compact Design

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.

Supporting Bluetooth App

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.

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.

Frequently Asked Questions

How much power can the KickAss Smart 12V 230Ah Ultra-X Lithium Battery deliver for my off-grid setup?
The KickAss Ultra-X battery delivers 12.8 volts nominal voltage with a rated capacity of 230Ah, providing 2944Wh of energy. It supports a maximum continuous discharge current of 230A and a pulse discharge current of 460A for 30 seconds. This means it can handle heavy loads and short bursts of high power, making it ideal for off-grid power systems, caravans, or boats where reliable, sustained energy is essential. The high discharge rate ensures your devices and appliances run smoothly without interruption.
Can I connect multiple KickAss Ultra-X batteries together to increase capacity or voltage?
Yes, you can connect up to 4 KickAss Ultra-X batteries either in parallel or in series, but not both at the same time. Parallel connections keep the voltage at 12.8V while increasing capacity and current, and series connections increase voltage up to 51.2V with the same capacity of 230Ah. This flexibility allows you to scale your battery bank to suit your power needs, whether you require longer runtime at 12V or higher voltage for specialised applications. Just ensure all batteries are the same model and batch for optimal performance.
How do I monitor the battery's charge status and health during use?
The KickAss Ultra-X battery features Bluetooth connectivity and supports remote display monitoring. Using the KA Lithium App or the optional remote display unit, you can view State of Charge (SOC), voltage, current, power usage, temperature, cycle count, and receive system warnings in real time. This smart monitoring capability helps you keep track of your battery's performance and health easily from your phone or fixed display, ensuring you can optimise usage and maintain safety without needing specialised equipment.
What is involved in setting up the KickAss Ultra-X battery for the first time?
The battery comes with mounting brackets, a 50cm RJ45 cable, and bolts for secure installation. It should be installed in a well-ventilated area, connected using the provided wiring diagrams, and charged only with a charger compatible with LiFePO4 batteries, respecting the max charge voltage of 14.6V and charge current of 230A. Following the manual's installation instructions ensures safe and efficient operation. Proper setup maximises battery life and performance, letting you enjoy reliable power wherever your adventure takes you.
Is the KickAss Ultra-X battery safe to use in different temperature conditions across Australia?
The battery operates safely within a charge temperature range of 0°C to +55°C and a discharge temperature range of -0°C to +60°C. It should be stored between 0°C and +30°C with 50% state of charge, and used in environments with 0-85% relative humidity. These temperature tolerances allow for versatile use in various Australian climates, from coastal to inland conditions. Ensuring the battery is not exposed to extreme temperatures helps maintain optimal performance and longevity.
What safety features does the KickAss Ultra-X battery include to protect against damage or hazards?
The battery includes a Battery Management System (BMS) that monitors cell voltage, temperature, and current to prevent overcharging, over-discharging, overheating, and short circuits. It provides system warnings and alerts via the app or remote display to keep you informed. This advanced safety system ensures your battery operates reliably and safely during use. Following the manual's guidelines on charging, installation, and handling further enhances safety, giving you peace of mind on every trip or off-grid installation.
