Hi,

You can route out the battery voltage do a breadboard and then measure the voltage with a multimeter.

Hi,

Are you able to measure the battery voltage when it's disconnected to the Thingy:91?

The Thingy:91 uses a battery-management-chip. If your common to i2c you may try to read the charging state and battery voltage directly.

See power_manager.c ADP536x to get an impression, how that may look like.
