Type-C USB 3A High Current IP2312 Polymer Ternary Lithium Battery Quick Fast Charging Board Charger Module CC/CV Mode 5V To 4.2V
Product name: 3A polymer ternary lithium battery fast charging board (note that it is not suitable for 3.2V lithium iron phosphate battery)
Main control chip: IP2312
Input voltage: 4.5~5.5V
Charging cut-off voltage: 4.2V/4.35V (2 versions of output voltage are available)
Charging current: 3A (current can be changed by adjusting resistance)
Indicator light: yes, red: working indicator light. Blue: full indicator light. Note: This product does not have a power indicator function and does not have a battery protection function. The store also sells lithium battery protection boards and power indicator boards.
Conversion efficiency: 3A 93%, 2A 94%, 1A 95% (data for reference only)
The IP2312 adopts a full 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 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, 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 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 again.
Current regulation description:
The default is 3A, remove the resistor 2A and replace it with a 135k resistor 1A
