Specification:
Origin: Mainland China
Type: Module
Condition: New
Product name: Quick Fast Charging Board (note: not suitable for 3.2V lithium iron phosphate batteries)
Model: AILAV1-0503V3
Main control chip: IP2312
Input voltage: 4.55.5V
Charging cut-off voltage: 4.2V/4.35V (there are two optional output voltage versions)
Charging current: 3A (current can be changed by adjusting the resistance)
Indicator light: yes, red: work indicator light, blue: full indicator light
Conversion efficiency: 3A 93%, 2A 94%, 1A 95%
IP2312 adopts a complete CC/CV charging mode:
When the battery voltage is below 3V, enter the trickle charging mode and charge the battery with a charging 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 approaches 4.2V and the charging current is less than 300mA, enter the constant voltage charging mode.
4. After entering constant voltage mode, stop charging every 4 minutes and check if the battery voltage is higher than 4.15V:
If it is higher than 4.15V, stop charging; Otherwise, continue charging and test after another 4 minutes.
5. After the battery is fully charged, if it is detected that the battery voltage is below 4.1V, it will start charging the battery again.
Current regulation instructions:
Default 3A, remove resistor 2A and replace with 135k resistor 1A
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
