8PCS 2A 5V Charge Discharge Integrated Module 3.7V 4.2V for 18650 Lithium Battery Charging Boost Mobile Power Supply Charge and Discharge Protection Converter Protection PCB Board Module
Brand: UMLIFEColor: BlackHardware Interface: USBSpecial Feature: quick Charging, PoweredTotal USB Ports: 4❃❃ 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).❃❃ 4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection.❃❃ The output opens automatically at the first time the load is connected.If the load is less than 50MA, automatically close the output after 30 seconds;If the load is greater than 50MA, the output opens automatically.❃❃ 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.❃❃ 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.
