Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 5V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions)
1) Lithium battery charging
2) Lithium battery protection (short circuit protection , over voltage protection , under voltage protection )
3)Nominal Voltage 3.7V or 5v charging voltage 12V
4) At the same time equipped with universal Micro USB charging interface, direct DC5V input to charge lithium battery
5) Two-color LED indicates the charging status, the green light is always on, and the charging is automatically stopped.
6) The module is equipped with two high quality 18650 battery holders for selection, in-line and patch
7) UPS power failure uninterruptible power supply function
When the power supply is powered, the load is directly supplied by the power supply via the boost circuit.
Once the power is turned off, the battery path is automatically activated to power the load via the boost circuit.
After the power is called, the power is restored from the power supply and the battery is also charged.
