Precautions
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, baby car battery, 550 or more power motor, 1W fisheye LED lamp, Customers who purchase in the above combination should pay attention to the following products: the massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring standby power supply, and other products.
2. For discharge products above 3A, the discharge rate of the battery should be more than 3C. Magnification formula: 1C rate battery, 2000 capacity equals 2AH*1=2A working current, 3C rate battery, 2000 capacity equals 2A*3=6A working current. In use, the battery will heat up or the battery rate is not applicable. The battery will be damaged quickly after long-term use.
3. After connecting the line, you need to charge first to have output.
