    Features:

    This is a multifunctional 3.7V/4.2V Mobile Power Diy  module,3 in 1 Function: charge,discharge and battery protection.
    It is very suitable for DIY mobile power.
     
     
    Comes with battery protection, do not need battery protection board 
    (if your battery comes with a protective board, it does not matter)
    Overcurrent protection(OCP)
    Overvoltage protection(OVP)
    Short circuit protection(SCP)
    Over temperature protection(OTP)
     
    Button mode:
     The button duration is longer than 50ms, but less than 2s, which is a short press action. Short press will turn on the battery indicator and boost output.
    The two consecutive short presses within 1 s will turn off the boost output and power display.
     
    Pin description:
    1 VIN : Charging port +
    2 GND : Charging port -
    3 GND : Battery port -
    4 BAT : Battery port +
    5 GND : Output port -
    6 VOUT: Output port +
    7 KEY : Output trigger port(Low pulse trigger)
     
    1 In discharge mode(In the charging mode,the KEY function is invalid),
    the KEY Trigger once,turn on the output;Continuous trigger twice: turn off the output.
       
    2 When the load access, it will automatically turn on the output.
    But if the load is less than 50MA, the output will be turned off after 30 seconds
        
    3 While charging, while discharge, it is allowed
     
     
    NOTE:
    If the output load current is less than 50MA, turn off the output after 30 seconds.
    If the output load current is greater than 50MA,continuous turn on the output

    This module is not suitable for uninterruptible power supply(ups).
