Preparation before assembly:
1. If using a new kernel, please note:
A. Must choose power lithium battery,
B. A set of six iron cores must be equipped with resistors and capacitors to make their voltages equal.
2. If the old battery is repaired, please test the voltage of each battery. If the voltage is different, charge each battery to the same voltage value.
Very important:
Before soldering the PCB, make sure each battery has the same voltage.
Note:
1.Due to the light and screen difference, the item's color may be slightly different from the pictures.
2.Please allow 1-3cm differences due to manual measurement.
Package includes:
1x Lithium Battery Charging Protection Board
