Description
Note: 1. Lithium battery protection board can not be used for lithium iron phosphate battery, xenon lamp, hand drill battery pack, electric fish battery pack, electric bicycle battery pack, children's car battery, 550 or more power type motor, 1W fisheye LED lamp.2. For discharge products above 3A, the discharge rate of the battery should be more than 3C.- Magnification calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A working current.- 3C rate battery, 2000 capacity equals 2AH*3=6A working current.3. The battery will be hot during use, indicating that the battery override is not applicable. This condition cannot be used for a long time, otherwise the battery will be damaged quickly.4. Strictly connect the wiring according to the diagram 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+), be careful not to short circuit.5. After connecting the line, you need to charge first to have output.6. When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please fill each set of batteries separately and use them in series. In the discharge test, the fastest battery in the voltage is the poor battery.- Do not mix good batteries with poor batteries. The closer the capacity/internal resistance of the three batteries is, the better. (2 good batteries + 1 bad battery = 3 poor battery use effect) Application: Massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring standby power supply, and other products.Feature:
