Hello,

is there a way that lopy can measure a LiPo battery?, I am doing a project and I want to know when the battery is dying.

thank you.

@jcaron thank you, I am using an expansion board, but I will try it whit pysense.

If you use a PyTrack or PySense with your LoPy, you can read the voltage directly using the read_battery_voltage method:

@robert-hh Thank you very much. I will try.

@jclo13 On the expansion boards, the battery is connected by an voltage divider to G3 aka P16. There, you can read a voltage proportional to the battery voltage.
