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 product is brilliant and works exactly as advertised - I did have an issue with the Bluetooth module on the first battery provided; however, this is not typical of the product and the RMA process was executed fairly and just.

    I will be purchasing more products into the future.

    Great battery for the dual battery system i installed in my 4wd. Primarily for running the fridge in the rear, this battery is slim and sits well in the battery tray, out of the way, neat and tidy.
