1. What should be paid attention to when assembling tool battery pack?
18650 power cell, model, voltage, internal resistance should be consistent, consistency is better, 10.8V 3 s, 14.4V 4 s, 18V 5 s. The voltage detection line must be connected to the detection line. Try to use better batteries instead of dismantling the electric core. Need spot welder.
2. When the protective plate is used to rep the original
Before changing the protection board, be sure to measure the voltage of each group of 18650 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 due to the inconsistent voltage of the battery pack. It is useless to rep the protection board. It is recommended to use new 18650 batteries.
