The Power Sonic PSL-BTP-121000 Rechargeable Lithium Phosphate Battery comes with an intelligent battery management system (BMS) that can monitor and optimize each cell during charge and discharge. This protects the battery from over-charge and over-discharge. The BMS embeds smart balancing algorithms that control all the cells in the battery, making sure they are constantly at the same voltage level.

You are able to monitor the State of Charge (SoC) and State of Health (SoH) of your battery from your phone or tablet.
