NOYITO 25A 3S Lithium Battery Protection Board 12V 11.1V 12.6V With Balanced Over-current Over-charge Over-discharge Protection 3S 25A Green
NOYITO 25A 3S Lithium Battery Protection Board 12V 11.1V 12.6V With Balanced Over-current Over-charge Over-discharge Protection
SAGE NOTES: 1: Please wire strictly according to the wiring diagram: 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+), can not short circuit! 2: After the wire is connected, it needs to be charged first then output. 3: When connecting 3 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 3 batteries is as close as possible (2 good batteries + 1 bad battery = 3 bad batteries). SPECIAL NOTE: The protection board can not be used for lithium iron phosphate battery, xenon lamp, hand drill battery pack, electric bicycle battery pack, children's car battery, 775 (4A) above motor, 1W fisheye LED lamp. The lithium battery protection board parameters: Maximum operating current: 20-25A (Note heat dissipation) Maximum instantaneous current: 35-40A Over charge voltage range: 4.25-4.35V±0.05V Over discharge voltage range: 2.3-3.0V±0.05V Quiescent current: less than 30uA Internal resistance: less than 100mΩ Balance current: 45 mA Charging voltage: 12.6V-13V Working temperature: -40 - +50°C Storage conditions: -40 - +80°C Short-circuit protection: protection, delay self-recovery. Size: 56454.0mm Test point description: Short-circuit S1 S2, P + P- will output voltage, indicating that all MOS protection works properly. If you add a normally open temperature test you can expand the temperature protection (interface labeled "T"). In the power range it applies to the following products: Massager battery pack, LED lamp backup power supply, 12V electronics, solar street light battery pack, monitoring standby power, and other products.
