LIVISN 3-2V 4S 100A 12-8V 14-4V LiFePo4 Lithium Iron Phosphate Battery Protection Board with Balance Over-Current Over-Charge Over-Discharge Short-Circuit Protection3-2V 4S 100A

PLEASE Note: 1. Please follow the connection diagram carefully to avoid short circuit; 2. After the wire is connected, first charge to activate the protection board. 3, When connecting 4 batteries in series, please make sure that the voltage of each battery is the same. If not, please full each battery separately and use it in series. In the discharge test, the battery with the fastest voltage drop was the bad battery. 4. Do not mix good and poor batteries. 4pcs battery capacity / internal resistance is as close as possible.  (2 good batteries + 2 bad battery = 4 bad batteries).
