Charge-discharge controller for 2 Li-Ion batteries 18650 HX-2S-D01 8A 7.4V

BMS 2S lithium battery protection board with 8A maximum continuous charge current and 4.25V full cell charge voltage.
Battery Management System (BMS) is an electronic board installed on a battery in order to control the process of its charge /discharge, monitor the condition of the battery and its elements, control temperature, the number of charge /discharge cycles, and protect the battery's constituent elements.
The control and balancing system provides individual control of the voltage and resistance of each battery element, distributes currents between the battery components during the charging process, controls the discharge current, corrects the loss of capacity due to imbalance, and ensures safe connection and disconnection of the load.
