New version update instructions:

Compared with the second version,the size is unchanged,the board circuit is optimized,and better components are replaced.
Added support for C-C data cable. The previous version only supported USB-C data cable.
Added support for the recognition of mainstream fast charging heads in the market. The fast smart charging head of the mobile phone can also be fully utilized.
Product name: 3A polymer ternary lithium battery fast charging board (note that it is not suitable for 3.2V lithium iron phosphate batteries)
Main Control Chip: IP2312
Input voltage: 4.5~5.5V
Charging cut-off voltage: 4.2V/4.35V (the output voltage is available in 2 versions)
Charging current: 3A (current can be changed by adjusting the resistance)

Indicator light: Yes,red: working indicator light. Blue: full indicator light. Note: This product does not have the power indicator function,and does not have the battery protection function. There are also lithium battery protection boards and power indicator boards for sale in this store.

Conversion efficiency: 3A 93%,2A 94%,1A 95% (data for reference only)
IP2312 adopts a complete CC/CV charging mode.
When the battery voltage is lower than 3V,it enters the 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 and charges 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,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 charging,and then check after another 4 minutes.
When the battery is fully charged,if it detects that the battery voltage is lower than 4.1V,it will start to charge the battery again.
