Lithium Battery LB-18-12-10

SKU: 6427

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 deep cycle 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.
