- PCB Dimension: 38x10x4mm
- Charging Voltage: 5V
- Charging Current: 400-500MA, generating heat is normal
- Output Voltage: 5V
- Output Current: 300~400MA, suitable for not high performance application and products
- Solder battery wires to B+ and B-
- Add 4.8-5V voltage on the charging terminal (P+ and P-) to activate protection circuit
- Test the raised voltage (V+ and V-, should be 5V)
- V+, V- is power output
- P+, P- is charging input
- B+, B- is battery terminal
- Blue LED on when charging, and then off when charging is done.
Functions of the board:
- Charging: Support single battery, or batteries connected in parallel.
- 5V output: output from battery 4.2V to 5V supply
- Protection of battery.
