Main control 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 of indicators.

Note: This product does not have a power indicator function, without battery protection function.

Conversion efficiency: 3A 93%, 2A 94%, 1A 95% (data is for reference only)

Current adjustment instructions:

Default 3A,remove 2A resistance and convert to 135K resistance 1A.

IP2312 adopts the complete CC/CV charging mode

When the battery voltage is lower than 3V, it enters trickle charging mode and charges the battery with 100mA charging current.

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, the battery 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 to charge, and then after another 4 minutes after detection.

When the battery is fully charged, if it is detected that the battery voltage is lower than 4.1V, it will start to charge the battery.

Package includes:

1 x IP2312 Charging Board
