Type-C USB Input High Current 3A Polymer Ternary Lithium Battery Quick Fast Charging Board IP2312 CC/CV Mode 5V to 4.2V QC3.0

Description

100% brand new and high quality

Features:

3A charging current,can change the current through adjusting resistance;2 types of cut-off voltage can be optional(4.2V/4.35V).

3A polymer ternary lithium battery,quick charging board,provides efficient working effects.

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.

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

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.
