Built around premium A-Grade LiFePO4 prismatic cells, this battery provides consistent performance, excellent energy efficiency and a long service life. Whether you're powering a caravan, camper trailer, canopy setup, touring vehicle or off-grid campsite, it delivers the reliable power you need for fridges, lights, charging devices, water pumps and other essential 12V equipment.

Full 120Ah of Usable Capacity
Unlike traditional lead-acid batteries that can only use a portion of their rated capacity, this lithium battery gives you access to the full 120Ah. With more available power packed into a smaller and lighter package, it's an ideal upgrade for anyone building their first 12V system or replacing an ageing AGM battery.

Compact Design for Easier Installation
Measuring just 238mm x 168mm x 258mm, it's significantly smaller than a traditional N70 battery, making it easier to fit into tight battery compartments and custom installations. Matching battery tray available as an optional extra purchase.

Advanced Battery Protection Built In
A sophisticated Battery Management System (BMS) continuously monitors the battery's operation to ensure safe and reliable performance. The integrated BMS protects against overcharging, over-discharging, short circuits and excessive temperatures. This intelligent protection helps maximise battery life while safeguarding both the battery and your connected equipment.

High Performance Power Delivery
With a 120A continuous charge and discharge rating, this battery can support demanding 12V applications while also accepting substantial charging currents for faster recharge times. From portable fridges and lighting systems through to larger touring setups, the battery is designed to keep your essential equipment running efficiently wherever your adventures take you.

Built for Australian Conditions
An IP65 rating provides protection against dust and water ingress, helping ensure dependable operation in harsh environments. The newly designed heavy-duty plastic case offers excellent durability while remaining lightweight and easy to handle.

Lightweight Yet Durable
Weighing just 12.55kg, this lithium battery is substantially lighter than comparable lead-acid alternatives. The reduced weight makes installation easier and helps minimise overall vehicle weight, while the durable construction stands up to the demands of regular travel and off-grid use.

Long Service Life
Thanks to premium LiFePO4 chemistry and high-quality cell construction, this battery is built for years of dependable service. With over 4000 charge cycles at 80% Depth of Discharge (DoD), it offers outstanding longevity and value, making it a smart long-term investment for any 12V power setup.

Optional Smart Shunt Compatibility
Want deeper insight into your power system? Pair the battery with an optional smart shunt to monitor key performance data including state of charge, current draw, charging activity and estimated runtime. It's a simple way to gain greater visibility and control over your battery system without stepping up to a fully featured smart battery.
