Battery Plastic Case Charging Protection Circuit Board PCB for Black Decker 20V Li-ion battery LB2X4020
Preparation before assembly:
(1). If a new core is used, please note:a. 18650 power lithium battery core must be selected,b. A group of 5/10 cores must be equipped with resistance and capacitance to make their voltage the same.
(2). If the old battery is repaired, please test the voltage at both ends of each cell. If the voltage is different, please charge each cell to the same voltage value.
Ensure that the voltage of each cell is the same before welding PCB.
