how to find low battery check?

Open PaekHyun opened this issue 7 months ago • 1 comments

It seems that the status of the battery is being checked using esp32's ADC. However, I understand that esp32's ADC can receive input up to 3.3V. The 18650 battery is known to have 4.2V when fully charged. But I wonder how I can check the status of the battery.
