12.8V 20AH SolarKing Lithium Battery CB-20-12-10

Home / Batteries Small

SolarKing lithium batteries are the future of battery storage. Lithium batteries are much lighter than traditional lead acid batteries and deliver unrivalled cycle life, more than 4 times more cycles compared to lead acid batteries.

These smaller capacity lithium batteries are perfect for battery back-up, security lighting, alarms and other applications when high capacity and small size and weight are required. The batteries are fully sealed and a built-in battery management system for safety protection.

If you are replacing an existing lead acid battery you can continue to use your same battery charging system as the built-in battery management system with do the rest for you. You will also notice that lithium batteries charge more efficiently than lead acid batteries so the recovery will me much quicker.
