The OzCharge Lithium range boasts a long list of safety measures, benefits and features including:
Superior Cell Quality ensuring a longer service life of up to 10 years and a massive 3000+ Cycles at 80% Depth of Discharge.
Active Cell Balancing Battery Management Systems (BMS) which detects faults 24/7 and protectively disconnects the battery - preventing short circuits, overcharging, undercharging, excessive current draw and more.
100% Cobalt Free means your battery has a much lower fire risk, and does not contribute to the environmental and social damages caused by the exploitation of poorer countries to supply the rapidly increasing demand for cobalt.
Designed for Australian conditions and manufactured even tougher, allowing the cylindrical cells to excel at a higher temperature range and easily handling harsh vibrations while off-roading or out on the waves.
UN38.3 Certification is THE stamp of quality, confirming our batteries safe to transport via air or sea with the highest level safety classification for battery cells and packaging.
5 Year Warranty with ongoing human support for the life of the battery.
The Power of ONE activates when combined with a dedicated OzCharge Lithium Charger which optimises charging for better performance and a longer life.
