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? Your battery will hold more power, last longer, and deliver a KickAss performance every

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

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.

Frequently Asked Questions
How much energy can the KickAss 12V 120Ah Lithium Deep Cycle Battery provide for my off-grid setup?
The KickAss 12V 120Ah Lithium Deep Cycle Battery provides 1536Wh of energy with 100% usable capacity, supporting continuous charge and discharge currents up to 120A. This means it can power typical off-grid devices like fridges for up to 200 hours or a KickAss LED strip for 53 hours.
This makes it ideal for weekend getaways or extended off-grid adventures, delivering reliable and consistent power for a variety of devices without worrying about capacity loss or unexpected shutdowns.
This makes it ideal for weekend getaways or extended off-grid adventures, delivering reliable and consistent power for a variety of devices without worrying about capacity loss or unexpected shutdowns.
Can I connect more than one of these batteries to increase my system’s capacity or voltage?
Yes, you can connect up to four KickAss 12V 120Ah batteries in either parallel or series configurations, but not both at the same time. Parallel connections increase capacity and current while keeping voltage at 12.8V, and series connections increase voltage up to 51.2V while maintaining 120Ah capacity.
This flexibility allows you to customise your power system to suit your specific needs, whether you want longer runtime or higher voltage for different appliances and setups.

How do I properly set up and charge the KickAss 12V 120Ah Lithium Battery when I first get it?
Your battery arrives at approximately 60% state of charge (SOC). Before first use, fully charge the battery using a charger designed for lithium batteries until it indicates full charge. Also, ensure all connections use appropriately sized fuses and that batteries are fully charged before connecting in series or parallel.
Following these steps ensures optimal battery performance and longevity, helping you get the most out of your KickAss battery from the start.

What safety features does the KickAss 12V 120Ah Lithium Battery include to protect against damage or hazards?
The battery includes a built-in Battery Management System (BMS) that prevents overcharging, over-discharging, short circuits, and overheating. It must be charged within specified voltage and temperature limits (0–60°C for charging), and the BMS actively monitors and protects the battery to ensure safe operation.
These safety features provide peace of mind, allowing you to confidently use the battery in your off-grid or adventure setup without compromising safety or performance.
These safety features provide peace of mind, allowing you to confidently use the battery in your off-grid or adventure setup without compromising safety or performance.
What is the expected cycle life of this lithium battery, and how does usage affect it?
The KickAss 12V 120Ah Lithium Battery is rated for over 4000 cycles at 80% depth of discharge (DoD) with a 0.5C discharge rate. Using shallower depths of discharge will increase cycle life, meaning the battery can last many years under typical off-grid usage conditions.
This excellent cycle life ensures long-term reliability and value, making it a smart investment for sustained off-grid power needs.
