Size: 35*35*3mmUpper limit working current: 8AUpper limit instantaneous current: 20AOvercharge voltage range: 4.25V+0.05VOver discharge voltage range: 2.5V+0.05VCharging voltage: 168V~17VQuiescent current: less than 30uAShort circuit protection: can be protectedDelayed self-recovery product features:1. Such as overcharge protection/overdischarge protection/short circuit protection/overcurrent protection2. With overcurrent protection, reasonable design, does not affect the battery pack3. With spot welding design, easy to assemble4. The static power consumption is small, and the overall power consumption is less than 30 microamps.Precautions:The lithium battery protection board cannot be used for lithium iron phosphate batteries, xenon lamps, hand drill battery packs, electric fish machine battery packs, electric bicycle battery packs, children's car batteries, motors or products with motors, 1W fisheye LED lights.For products with a current above 3A, the battery discharge rate should be above 3C.Rate formula: 1C rate battery, 2000 capacity equal to 2AH*1=2A working current 3C rate battery, 2000 capacity equal to 2AH*3=6A working current1. Strict wiring OV(B-), 3.7V(B1), 7.4V(B2), 11.1V(B+) do not intentionally short circuit!2. After the line is connected, it needs to be charged first, and then there will be output3. When connecting 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same, if not, please fully charge each group of batteries separately and then use them in series. During the discharge test, the battery with the fastest voltage drop is the poor battery.A note: don't mix good batteries with bad batteries!The closer the capacity/internal resistance of the 3 batteries is, the better! (The effect of 2 good batteries + 1 bad battery =the effect of 3 bad batteries). indivualIn use, the battery will heat up, that is, the battery rate is not applicable. In this case, if the battery cannot be used for along time, the battery will be damaged quickly.Applicable products: massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring backup power supply, and other products.
