2020 new edition 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 line, previous version only supported USB-C data line.
Increase the recognition support for mainstream fast charging heads in the market. The fast intelligent charging head of the mobile phone can also be fully utilized.

​ Name: 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 chip: 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 charge indicator. Note: This product does not have battery capacity indicator function, no battery protection function, in our store has a lithium battery protection board and battery capacity indicator board for sale.
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 higher 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.

Charging Current adjustment instructions:
Default 3A, remove resistor 2A, replace with 135k resistor 1A
