Why does the drone need to change batteries after every 1min flight?

[AlexWUrobot]

The issue "change batteries after every 1 min flight " does not happen.
However, the unexpected switching from offboard mode to AUTO.LAND mode still happens.
There is the following discussion.

Why does drone suddenly switch AUTO.LAND mode from offboard mode when descending? (Failsafe enabled: no offboard)

Thank you very much for your help. Is there any min height setting in QGroundControl, which will trigger the AUTO.LAND mode? During my offboard control descending, the drone suddenly switch to AUTO.LAND mode from offboard mode. I am confused about that and the unexpected switch mode makes the programmed descending drone has a unexpected spike, like the video at 1:47 There is the Pixhawk log and the screenshot of the distance sensor. [image] At the time stamp: from 1686240419 to 1686240…

Thanks a lot for your help again ^ ^
