SPECIFICATIONS

3A polymer ternary lithium battery fast charging board(note that it is not suitable for 3.2V lithium ironphosphate battery)

Main control chip: IP2312

lnput voltage: 4.5~5.5V

Charge cut-off voltage: 4.2V/4.35V (output voltageis available in 2 versions)

Charging current: 3A (can change current by adjustingresistance)

lndicator light: Yes,

red: Work indicator.  Blue: Full of

indicators.  Note: This product does not have a powerindicator function,without battery protection function.  Conversion efficiency: 3A 93%,2A 94%,1A95%(data is for reference only)

The lP2312 uses a full CC/CV charging mode.

when the battery voltage is rboroes the battery with

a charge current of 100mA.

When the battery voltage is greater than 3V, enter theconstant current charging mode to charge the batterywith the set constant current charging current.

constant voltage charging mode.After entering theconstant voltage mode,the cnargimigte is detectedevery 4 minutes, and the battery voltage is qetcttato be higher than 4.15V: ifit is higher than 4.15V , the

charging is stopped; otherwise, the charging is

continued, and then the detection is performed after4 minutes.

When the battery is fully chargea,A'1v it will turn on

to charge the battery.

Current adjustment instructions:

Default 3A, remove resistor 2A, replace with 135kresistor 1A
