l This product does not contain batteries
l 21700 power cell, model, voltage, internal resistance should be consistent, consistency is better, 10.8V 3 strings, 14.4V 4 strings, 18V 5 strings. The voltage detection line must be connected to the detection line. Try to use better batteries instead of disassembling them. Need spot welder.
l Before changing the protection board, be sure to measure the voltage of each group of 21700 cells to ensure that the cell voltages are consistent. The protection board only plays a protective role and cannot balance the voltage. The battery cannot be charged or discharged because of the inconsistent voltage of the battery pack. It is useless to replace the protection board. It is recommended to use new 21700 batteries
