6pcs 2A 5V Charge Discharge Integrated Module 3.7V 4.2V for 18650 Lithium Battery Charging Boost Mobile Power Protection PCB Board Module
★ MCU users, if you accept a small load KEY can be connected to the microcontroller about 20s to provide a low level allows the module to continue working. Trigger mode: low level trigger (ground)
★ In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output
★ The first time the load is connected, the output is automatically turned on. If the load is less than 50mA, the output will be automatically turned off after 30 seconds; if the load is greater than 50mA, the output will be automatically turned on
★ Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V)
