Photo and product description

Type C USB C Input High Current 3A 5V To 4.2V 4.35V Polymer Ternary Lithium Battery Fast Charging Board IP2312 Electronic Tool

3A polymer ternary lithium battery fast charging board (note that it is not suitable for 3.2V lithium iron phosphate battery)
Model: AILAVI-0503V1
Main control : IP2312
Input voltage: 4.5~5.5V
Charge cut-off voltage: 4.2V/4.35V (output voltage is available in 2 versions)
Charging current: 3A (can change current by adjusting resistance)
Indicator light: Yes, red: Work indicator. Blue: Full of indicators. Note: This product does not have a power indicator function, without battery protection function.

Conversion efficiency: 3A 93%, 2A 94%, 1A 95% (data is for reference only)

The IP2312 uses a full CC/CV charging mode.
When the battery voltage is lower than 3V, it enters the trickle charge mode and charges the battery with a charge current of 100mA.
When the battery voltage is greater than 3V, enter 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, it enters the constant voltage charging mode. After entering the constant voltage mode, the charging is stopped after every 4 minutes, and the battery voltage is detected to be higher than 4.15V: if it is higher than 4.15V, the charging is stopped; otherwise, the charging is continued, and then the detection is performed after 4 minutes.
When the battery is fully charged, if it detects that the battery voltage is lower than 4.1V, it will turn on to charge the battery.
Current adjustment instructions:
Default 3A, remove resistor 2A, replace with 135k resistor 1A
PCB size: 31*15mm
USB socket protrudes about 1mm
