KickAss 12V 120Ah LiFePO4 Lithium Battery & Remote Display Unit Feature Overview

Monitor Your Battery Status: Never question your lithium battery's health again! The colour screen takes the guesswork out of battery maintenance. Monitor your battery temperature, voltage, current draw, time to empty, charge status and more.

Safe Lithium Iron Phosphate Chemistry (LiFePO4): LiFePO4 is one of the most stable and safest 12V lithium chemistries available. This means KickAss LiFePO4 batteries are safe even for the toughest of tracks, with 200+ battery cycles at 100% depth of discharge.

More Usable Capacity: Unlike AGM batteries that can only safely use up to 50% capacity, the KickAss 120Ah Lithium Battery can safely use up to 80% capacity, giving you a full 96 usable amps.

Lightweight: Weighing only 14.3kg—about half the weight of a similar sized sealed lead acid battery—makes it far easier to move and install the KickAss 12V Lithium Battery into your setup.

KickAss Integrated Battery Management System (BMS): The KickAss BMS ensures your battery remains safely within all parameters, protecting your 12V lithium battery from short circuits, low voltage, overloads and more.

Durable ABS Casing: With high tensile strength and superb resistance to impacts and chemical erosion, our high-quality ABS container ensures long lifespan.

The KickAss Smart 12V 120Ah Lithium Slimline Battery delivers a rated capacity of 120Ah, with an energy output of 1536Wh, a nominal voltage of 12.8V, and a maximum continuous discharge current of 120A. It also supports a pulse discharge current of 240A for 30 seconds. This means you get reliable, high-capacity power ideal for extended off-grid use.
With 120Ah capacity, this battery can run your appliances longer than standard options, while the high continuous and pulse discharge currents ensure it can handle demanding loads like fridges, pumps, and power tools without strain.

Yes, you can connect up to four KickAss Smart 12V 120Ah Lithium Slimline Batteries in parallel or series configurations. Each battery must be fully charged before connecting, and the system supports Bluetooth and remote display monitoring for combined setups.
This flexibility allows you to scale your power system easily, whether you need higher voltage or increased capacity. The built-in Battery Management System (BMS) ensures safe and balanced operation across all connected batteries.

The battery ships at approximately 60% state of charge (SOC) and should be fully charged before first use, ensuring your charger indicates a full charge before disconnecting. Use the specified charger and connect loads via appropriately sized fuses.
Starting with a full charge optimises battery performance and longevity. You can also download the KA Lithium App for Bluetooth monitoring and connect the optional Remote Display Unit for real-time status updates, making setup and operation straightforward and user-friendly.

The battery includes a Battery Management System (BMS) that prevents overcharging, over-discharging below 10V, overheating, and short circuits. It operates safely within a charge temperature range of 0 to +55°C and discharge temperature range of -20 to +60°C.
These protections ensure your battery and connected devices remain safe during use. Additionally, the battery is IEC62619 certified, reflecting compliance with international safety standards, giving you peace of mind in rugged off-grid environments.

Yes, the KickAss Smart 12V 120Ah Lithium Slimline Battery supports Bluetooth monitoring via the KA Lithium App and can connect to a Remote Display Unit. This allows real-time monitoring of voltage, current, temperature, and state of charge for one or multiple batteries in series or parallel.
This advanced monitoring capability helps you manage battery performance proactively, ensuring you always know your power availability and can optimise usage for longer battery life and better system reliability.

The battery measures 395mm long, 110mm wide, and 307mm high, weighing 14.35kg. Its slimline design makes it ideal for installation in narrow or confined spaces without compromising capacity or power.
This compact form factor is perfect for caravans, boats, or small off-grid setups where space is limited. The included mounting bolts and optional battery tray accessories simplify secure installation and integration into your system.

The battery requires a maximum continuous charge current of 120A and a maximum charge voltage of 14.6V. It should be charged within 0 to +55°C and always with a charger designed for lithium LiFePO4 batteries to prevent damage.
Following these charging parameters ensures safe, efficient charging and maximises battery lifespan. The built-in BMS safeguards against overvoltage and overheating, so you can confidently use your battery with compatible lithium chargers.

Yes, the battery operates safely within a discharge temperature range of -20°C to +60°C and a charge temperature range of 0°C to +55°C, making it well-suited for a wide variety of Australian climates.
Its robust design and thermal protections allow reliable performance in cold winters and hot summers alike, ensuring your off-grid power remains consistent and dependable no matter the environment.
