  1. Hi Oscar,

    thanks a lot for your comment and notifying me of the typo. 🙂

    I am not sure I am understanding your question very well. As I see in your charts (I guess you are talking about the field 4 chart) the values you are reading are high. As far as I know, ESP8266 ADC reads values from 0 to 1.0 Volts.

    In my case, I am using an ESP32. It reads volts from 0 to 3.3, giving you a value from 0 to 4096. Ion-Li batteries reach up to 4.2Volts that exceeds the maximum value that the ADC can read, so I had to use a voltage divider.

    Si lo prefieres, por comodidad de los dos podemos hablar en castellano, que no se qué hacen un uruguayo y un español hablando en inglés… 😉
