Lithium Battery BMS 18650 Charger Protection PCB 1S 2S 3S 4S 5S 6S Li-ion Li-Po
BMS (Battery Management System) boards provide undervoltage, overvoltage and short circuit protection |
The BMS is designed to charge and manage the use of a lithium battery. It will manage the charging when used with an apropriate constant current power supply for the battery(s). It will also protect the battery(s) from both over voltage and under voltage. It also features over current and short circuit protection
