Applications:
It is used for 5 series 3.7V Li-ion batteries, massager battery pack, LED light backup power supply, solar street light battery pack, monitor standby power supply and so on.

Notice:
1. Please strictly according to the diagram wiring to avoid possible damage to the chip. (Connect wires refer to the "wiring diagram"(NO.5 picture).
2. After connection, it need to charge activation first, then will have the output.
3. Do not mix good batteries with bad ones.
4. The closer the internal resistance of the five battery capacities is the better.
5. It can not be used for lithium iron phosphate battery, xenon lamp, hand drill battery pack.

Package includes:
3 x 5S 15A Lithium Battery Protection Board
3 x Wire
