IP2312 Module 3A Type C USB C Input High Current 3A IP2312 Fast Charging Circuit 5V To 4.2V 4.35V Polymer Ternary Lithium Battery Replace TP4056 ETA4096 Module Adapters 3A High Current IP2312 Circuit 

Specifications:

• 3A polymer ternary lithium battery fast charging board (Not suitable for 3.2V lithium iron phosphate battery)
• Main control chip: IP2312
• Input voltage: 4.5 to 5.5V
• Charging cut-off voltage: 4.2V/4.35V (the output voltage is available in 2 versions)
• Charging current: 3A (current can be changed by adjusting the resistance)
• Indicator light:
• Red: working indicator
• Blue: full indicator light.
• Note: This product does not have the power indicator function, does not have the battery protection function,
• Conversion efficiency: 3A 93%, 2A 94%, 1A 95% (data for reference only)
• IP2312 adopts a complete CC/CV charging mode.

Note:

• 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 and charges 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 another 4 minutes.
• When the battery is fully charged, if it detects that the battery voltage is lower than 4.1V, it will start to charge the battery again.

Note: this product does not have the power indicator function, does not have the battery protection function, the store also has the lithium battery protection board and the power indicator board to sell.
