Note:
For continuous currents exceeding 50A or requiring lower heat generation, solder the copper wire as follows.
Precautions:
Note 1: The B-, C-, and P- lines should be connected with thick wires, and ensure that the pads are properly soldered to the positive and negative electrodes of the corresponding device.
Note 2: before installing the protection board, the battery must match well (each battery voltage difference is not higher than 0.05V, the internal resistance difference is not greater than 5mΩ, the capacity difference is less than 30mAh), the protection board is to protect each string of batteries, as long as A string of battery voltages that are too high or too low will protect it. The better the battery consistency, the more durable the entire battery, and the best performance of the protection board.
Note 3: Single batteries must be connected in parallel to the required number of battery packs, and then use the batteries in series.
Note 4: Whe
