Our latest range of 135Ah lithium (LiFePO4) deep-cycle batteries are the most reliable, technologically-advanced batteries we have ever manufactured. With Bluetooth® monitoring, outstanding performance characteristics and full international certification, you’ll never be caught short of 12v power on your 4wding and camping adventures again! Best of all, we’ve packed 135Ah of usable power into a standard Group 27 (N70) size case, meaning they are compatible with standard-sized battery boxes and trays.

This model includes our latest innovation: the cells are wrapped in heating film, which is automatically switched on by the BMS when it detects the ambient temperature has dropped under 0°C. This means that, unlike other batteries on the market, you can continue to charge your battery even in freezing weather!

These batteries are made using best-in-class robotic manufacturing processes with rigorous quality assurance (including serialised tracking) and pre-shipment cycle testing. We even store the test report for each battery for later reference if needed. That’s why we can now confidently offer you a 5-year Australian warranty.

Our 135AH deep-cycle lithium batteries are constructed from the highest quality 26700 high-discharge cylindrical cells. The cells are carefully matched to ensure the difference in internal resistance is less than 1m? and voltage difference is less than 5mV. They are then ultrasonically welded using automated equipment to ensure a strong connection is made between each cell, and encased in custom-molded ABS plastic cell holders to ensure reliability and consistency even when subjected to shock and vibration.

Prismatic and cylindrical cells both have inherent advantages and disadvantages. Batteries which use prismatic cells are somewhat lighter than those with cylindrical cells, and are easier to manufacture due to having fewer connections between cells. Cylindrical cells, on the other hand, are usually more efficient in their energy usage, produce somewhat less heat and tend to be more reliable than their prismatic counterparts.

The improved cell reliability and efficiency of cylindrical cells are what made us decide, like Tesla and Rivian, to manufacture these batteries from cylindrical cells.
