#1	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
#2	4 in 1 Charging Discharging Lithium Battery Protection Battery Level Indicator Module Lithium battery protection function overcurrent overvoltage overtemperature short circuit protection
#3	The output opens automatically at the first time the load is connectedIf the load is less than 50MA automatically close the output after 30 secondsIf the load is greater than 50MA the output opens automatically
#4	High Power High Efficiency Discharge efficiency up to 96 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
#5	Can be applied to solar panel turning to mobile phone charging car charging retrofit driving recorder power supply household power supply intelligent plugging transformation fast charging adapter etc
