A-grade prismatic cells

The KickAss 12V 120Ah Deep Cycle Lithium Battery uses A-grade LiFePO4 prismatic cells, ensuring superior quality and performance. While other brands use inferior recycled or pouch cells in their batteries, this KickAss unit uses A-grade cells that guarantee capacity and provide a longer life cycle.

Let’s get techy – our A-grade cells are batched during the manufacturing process. This allows us to optimise their performance once they’re assembled in the battery pack, because the cells will charge and discharge at the same rate. What does this mean?

    Batteries

    Best thing for my van. These batteries have changed the way everything works inside, l can cook with my kickass electric hot plate and have the Kickass heater running at the same time, with lights on.

    I love KICKASS batteries. The staff at the new Melbourne store were fantastic.

    Thanks guys

    Could not be happier with this Battery (part of a bundle)

    Bought this as a bundle with dcdc charger etc, at a great price during Winter specials,

    When there seemed to be a delay in delivery due to a local courier (Tasmanian speed!) I contacted Customer Service who gave them a nudge so it was delivered and installed by the weekend. I'm so stoked with the gear in the Hilux canopy that I bought another charger and inverter for the camper trailer. So brilliant service and products -highly recommended.

    Battery upgrade

    Upgraded from a Kickass AGM to a 120ah Lithium.

    Very happy so far. I have purchased a fair amount of kickass products and have also encouraged mates to do the same. Keep up the great work!

    KickAss 12V 120Ah Lithium Deep Cycle Battery LiFePO4

    I’ve had my Kickass AGM Portable Battery Power Station for the last three years, and recently needed a new battery. The team at the Sydney Store were incredibly friendly and helpful. Not only did I find a much lighter 120AH lithium battery that fit perfectly into my existing AGM Power Station, but one of the staff members even connected it for me on the spot, straight into the back of my ute — ready to use!

    I’m genuinely impressed with the young team’s knowledge and the old-fashioned customer service they delivered. It’s rare these days, and I’m proud to support a business like this.

    Keep up the great work, KickAss team
