Multifunctional and Safe: 4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection.
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. Allow discharge while charging. (Attention: At this time output voltage 4.7 / 5V)
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.
Widely Applications: This module 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.
