NOYITO 30A 4S 3-7V Lithium Battery Protection Board 14-8V with Balance Over-Current Over-Charge Over-Discharge Protection

USAGE NOTES: 1: Please wire strictly according to the wiring diagram,can not short circuit! 2: After the wire is connected, it needs to be charged first then output. 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. Explain: Do not mix good and bad batteries together! The capacity/internal resistance of the 4 batteries is as close as possible (2 good batteries + 2 bad battery = 4 bad batteries). The lithium battery protection board parameters: Maximum operating current: 30A Maximum instantaneous current: 56A Over charge voltage range: 4.25-4.35V±0.05V Quiescent current: less than 30uA Internal resistance: less than 20m? Charging voltage: 16.8V-18V Charging current: 20A Max Working temperature: -40 - +50°C Storage conditions: -40 - +80°C Short-circuit protection: Trigger condition: External load shorted. Release condition: disconnect the load. Size: 56*48*4.0mm Package Included: 1pcs 30A 4S 3.7V Lithium Battery Protection Board
