When measuring higher voltages (like a battery) with the ESP32 ADC, you typically use a voltage divider to scale down the voltage to a range the ADC can handle. A voltage divider uses two resistors ...

First, I hope you are all doing well. I am currently working on a project that will be using a solar panel interface as well as, for now, a 3.7V lipo battery (at night). So the Solar panel would ...

[Victor] ended up using a small 100mAh 3.7V Lipo battery from a tiny quadcopter for this build. 100mAh isn’t a lot, but in sleep mode, the ESP only uses about 15mAh, or about 6 hours of run time.
