Adafruit Feather M0 Adalogger
LiPoly batteries are ''maxed out'' at 4.2V and stick around 3.7V for much of the battery life, then slowly sink down to 3.2V or so before the protection circuitry cuts it off. By measuring the

All About Batteries
To get Wh, multiply the Ah by the nominal voltage. For example, lets say we have a 3V nominal battery with 1Amp-hour capacity, therefore it has 3 Wh of capacity. 1 Ah means that in

Any way to get or estimate the battery percentage
You can read the battery voltage by using the Arcada library function readBatterySensor () (it multiplies by two to give the actual voltage), by using analogRead (A6) in Arduino, or by using
