    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.

    Great Quality.

    I needed a lithium battery for my caravan. After some extensive research, and checking and comparing batteries from various suppliers, I decided to purchase the Kickass 120AH battery. The specifications were good and it was certified to IEC62619 for RV use. Grade A cells are used in the manufacture, and I found it charged up ready for first use very quickly using a suitable lithium charger. Good quality battery and a certified BMS system was very important, and this battery ticked every box.

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.
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.
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.
Can I use this battery in extreme temperatures or harsh environments?
The battery is designed to operate safely within a discharge temperature range of -20°C to +65°C and a charge temperature range of 0°C to +60°C. It should be installed in a well-ventilated area and protected from extreme temperature exposure to maintain optimal performance.
This wide operating temperature range makes the battery versatile for many Australian outdoor and off-grid conditions, ensuring dependable power wherever your adventures take you.
What accessories or components come with the KickAss 12V 120Ah Lithium Battery to help with installation?
The battery includes two M8 x 16mm bolts with flat and spring washers for secure wiring connections. Optional accessories such as the KickAss N70 Tray and Battery Linking Cables are available to simplify installation and battery bank configuration.
These components and accessories streamline setup, making it easier for you to integrate the battery into your existing or new off-grid power system with confidence and convenience.
How does the battery handle continuous high current loads during use?
The KickAss 12V 120Ah Lithium Battery supports a continuous charge and discharge current of up to 120A, allowing it to power high-demand devices like large ovens drawing 20A for 6 hours or KickAss E BBQs drawing 46A for 2.6 hours.
This robust current handling capability ensures your battery can meet the demands of a wide range of appliances, giving you reliable power for cooking, lighting, and entertainment on your adventures.
