3A High Current Polymer Ternary Lithium Battery Charging Board 5V to 4.35V 5V to 4.2V Supports TypeC InputItem NO.: AILAVI-0503V3

Lithium Battery Charging Board

Product Information:

● Product name: 3A polymer ternary lithium battery fast charging plate (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: 4.2 V/4.35V (providing two output voltages) Charging

● Current: 3A (current can be changed by adjusting the resistance)

● Indicator light: Yes, red: work indicator light. Blue: Full indicator light. Note: This product does not have a power indicator function or battery protection function. The store also sells lithium battery protection panels and battery indicator light panels.

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

● IP2312 adopts full CC/CV charging mode.

● When the battery voltage is lower than 3V, enter the Trickle charging mode and charge the battery with 100mA charging current.

● 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. 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, charge; Otherwise, continue charging and check again after 4 minutes.

● After the battery is fully charged, when it is detected that the battery voltage is below 4.1V, it will restart charging the battery.

● Current regulation instructions: default to 3A, remove 2A resistor and replace with 135k 1A resistor
