Product Description
Specifications:
Name: 3A polymer ternary lithium battery fast charging board ;(note not suitable for 3.2V lithium iron phosphate battery)
Main control chip: IP2312
Input voltage: 4.5~ 5.5V
Charging cut-off voltage:4.2V/4.35V
Charging current: 3A (Current can be changed by resistance)
Indicator light: Yes(Red is the working indicator light, and blue is the full indicator light.)
Conversion efficiency: 3A 93%, 2A 94%, 1A 95%
Current adjustment instructions: default 3A, remove the resistor 2A, and replace it with a 135k resistor 1A.
lp2312 adopts complete CC/CV charging mode:
1.When the battery voltage is lower than 3V, enter trickle charging mode to charge the battery with a charging current of 100mA.
2.When the battery voltage is greater than 3V, enter the constant current charging mode to charge the battery with the set constant current.
3.When the battery voltage is close to 4.2V and the charging current is less than 300mA, enter 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: ifit is higher than 4.1 5V, stop charging; otherwise, continue charging, and then check after 4 minutes.
4.When the battery is full, if the battery voltage is detected to be lower than 4.1V, it will be turned on to charge the battery again.
Package Includes:
5 x 3A Polymer Ternary Lithium Battery Quick Fast Charging Board
