Feature:1. Multiple Protection: Possess multiple protection functions such as overcharge protection, overdischarge protection, short circuit protection, etc.2. Separated Charging And Discharging Port: The charging port and the discharging port are separated, easy for you to use3. Extend Battery Pack Life: BMS PCB protection board can effectively works for extend the life of the battery pack4. Good Quality PCB: Adopt good quality PCB materials, with reliability and miniaturization, good maintenance and interchangeability5. Prevent Overcharging: Li ion battery protection board is suitable for power charging, which can be used to prevent electric bicycles from overchargingHow to Use:1: The Battery Connection Sequence: First connect B‑, then connect the battery voltage detection terminal, the sequence is reversed when removing.2: The cell voltage detection terminal is connected by a 2.0 pitch flat cable, the pin of CN1 is B‑, the second pin is B1, the third pin is B2, and so on, the 1 pin is B+.3: The battery cell voltage detection line uses a standard cable, B‑, P‑, C‑ need to choose the appropriate wire diameter according to the continuous discharge current and the size of the charging current.4: After the b
