Battery 18650 Fast Charger Board Type C Input:

Specifications:

Input Voltage Range: 4.5 - 5.5V (USB Type C input)
Charging Current: Default 3A, remove resistor to convert to 2A. For 1A output add a 135K Resistor
Charging Cut-off Voltage: 4.2V Default (Can be changed to 4.35V by soldering the small older points together on the board)
Led Indicator: Red: Charging; Blue: Full

IP2312 Chip adopts the complete CC/CV charging mode
When the battery voltage is lower than 3V, it enters trickle charging mode and charges the battery with a charging current of 100mA.
When the battery voltage is greater than 3V, it enters the constant current charging mode to charge the battery with the set constant current charging current.
When the battery voltage is close to 4.2V and the charging current is less than 300mA, the battery enters the constant voltage charging mode. After entering the constant voltage mode, stop charging every 4 minutes and check whether the battery voltage is higher than 4.15V. If it is higher than 4.15V, stop charging; Otherwise, continue to charge, and then check after another 4 minutes.
When the battery is fully charged, if it detecteds that the battery voltage is lower than 4.1V, it will start to charge the battery again.

Note that this unit is not suitable for 3.2V lithium iron phosphate battery. There is no battery protection function.
