This Li-Po Battery Indicator is:
1. To check the voltage fo Li-Po Battery with a 2S and 3S configuration (as a battery pack fuel gauge)
2. To attach onto RC models to monitor voltage levels. This is to prevent over discharge of your Li-Po packs. How this is done is by visual cues of the LED (Light Emitting Diode).
