Get double the power in a compact, lightweight form with the VoltX 12V 120Ah Lithium Battery LiFePO4. This deep cycle battery charges your appliances between 2-4 hours and can be used in a wide variety of other applications such as power tools, medical devices, and security systems. Aside from recreational activities, it's perfect for storing at home as well for backup in case of a power outage.

LiFEPO4 batteries are known for their safety features, specifically their built-in battery management system (BMS). It helps protect the battery against over-charge, over-discharge, and short-circuiting to prevent damage and common hazards involved when using lithium batteries as well.

This 12V lithium battery boasts the same advanced features for easier maintenance and maximum performance every time, whether you're using it outdoors or as backup power at home. Even better, it now comes with a 3-year Australian warranty to help extend your battery’s lifespan.
