Battery Charge-discharge Module Charging Protection Board Boost Converter Step-Up Power Module

Label:Yes Charging current: 2.4a ± 5% Input voltage range: 5 ~ 5.5V Static current at battery end: < 30uA Boost output voltage: 5V ~ 5.15v (line loss compensation) Packing List:1Pc Charge-discharge Module Product features: type-C input, high accuracy of charging voltage. Boost output current: 2A Charging cut-off voltage: (4.2v/4.35v) ± 0.5% Boost output voltage ripple: 100mV Boost conversion efficiency: 92.5% (3.6V input, 5v2a output) Introduction: When the load current is less than 50mA continuously, the output will be turned off. It supports the external key, which is connected to the K point and the output negative pole. Short press to turn on the power display and turn on the 5V output. Two consecutive short presses will turn off the power display and turn off the 5V output. When the charging current drops to 100mA after reaching the final floating charging voltage, the charging cycle will be automatically terminated. When the battery voltage drops below 4.1V, the charging cycle starts again. When the battery voltage is lower than 2.8V, the battery will be pre charged with a current of 180mA. The usb-a base welding position is provided on the back of the product, which can be installed manually. It supports discharging while charging. Description of charging voltage switching As shown in the figure below, the voltage can be changed by adjusting the solder joint of the pad. Be sure to power off the operation!

Note: power off operation is required to adjust the charging voltage setting; the usb-a base on the back of the module needs to be welded by the user, and we will provide a female base with the product.
