No, I did not. Can you list procedure? Judging from your expertise that would indicate the logs would show the reason for failure during flight, yes. I alternate between 2 batteries and it is
the first batt problem I have encountered with the P4. My P3P has 3 batteries never a problem. I appreciate your help in discovering what happened. I did get a message in the go app
that stated firmware inconsistences detected followed by the batt error. I deleted firmware and re-installed including compass and IMU calibrations.
