I've got a more or less generic version of a Wemos Lolin32 that has a LiPo jack and built in battery charger. What I'm looking to do is pull a value of the remaining level of charge in the battery. I. LOLIN32 ESP32 Dual Core WiFi+Bluetooth Development Board with Battery Charger Operating Voltage: 3.3V: Digital I/O Pins: 26: Analog Input Pins: 12: Clock Speed(Max) 240Mhz: Flash: 4M bytes: Length: 5.8mm: Width: 2.54mm: Weight: 5.8g: Battery Connector: PH-2 2.0mm; Documents and Downloads. LOLIN32 Module Support page; LOLIN32 Schematic; ESP32 Datasheet; ESP32 Technical Reference manual. Unfortunately, no direct method of battery voltage measurement is built into the system. But it should be quite easy to implement such a thing: Use a voltage divider on the battery to get a 1.1V max. For a 4.2V cell, this can be achieved using a 27k and 100k resistor. Note, that the ADC of the ESP32 is set to 1.1V range by default

  6. The ADC is 12-bit which is why the 3.3/4096 (ref voltage/max counts) conversion factor is in there. When the analog read returns 0, the battery voltage is 0, and when it returns 4095, the battery voltage is 4.2 V. The response of the ESP32 ADCs is apparently non-linear so you will have to calibrate the response and correct for maximum accuracy

Unter Volt versteht man die elektrische Spannung einer Zelle oder Batterie. Die Spannung entsteht durch das Zusammenspiel der Elektronen in der Zelle. Die Nennspannung von Li-Ionen Zellen liegt bei 3,6 (LiFe) und 4,2 (LiMa ,LiPo) Was ist Volt? Die Stromeinheit Volt wurde nach dem italienischen Physiker Alessandro Volta benannt. Er lebte im 18. Jahrhundert und hat viel zur Erforschung der Elektrizität beigetragen. Er gilt unter anderem als Erfinder der Batterie wie zum Beispiel der 12 Volt Batterie oder der 9 Volt Batterie Lithium-Schwefeldioxid-Batterie LiSO 2: 3,0 Volt: 2,7 Volt: Anwendung meist im militärischen Bereich. Lithium-Kohlenstoffmonofluorid-Batterie Li(CF) n: 3,23,0 Volt : 3,12,5 Volt: Lithium-Kohlenstoffmonofluorid-Batterien haben etwas höhere Strombelastbarkeit und Kapazität als Lithium-Mangandioxid-Batterien, sind aber teurer. Sie werden daher für Anwendungen verwendet, bei denen. Thankfully Adafruit has our backs and exposes the battery voltage on Pin 35, a non-exposed ADC pin that we can read from. Adafruit notes on the Power Management page: If you're running off of a battery, chances are you wanna know what the voltage is at! That way you can tell when the battery needs recharging. Lipoly batteries are 'maxed out' at 4.2V and stick around 3.7V for much of the.
