Short voltage drop spike, Mini 4 Pro

scottjo2152 · Oct 13, 2025

Helping a friend with a Mini 4 Pro. He had a brief voltage drop spike during a flight that initiated a battery level low, RTH message. It quickly went away and the battery level was OK. This happened at about 9 min, 1 sec into the flight. Battery was a plus size and it looks fine after the flight Any idea what was the cause? Flight log file is attached.
Thanks,
Scott

Cannot open the file. I've seen reports of this in logs for the NEO when they fly away.

I am having difficulty loading the flight log in the correct form. I've done it before with my own logs, maybe this is different since it came from another source? Anyway, here is another try to show the log.

I have the instructions that are posted here in the forum frequently. I do have this log loaded in my Air Data but do not see how to copy just that one log here from Air Data.

DJI Flight Log Viewer - PhantomHelp.com

Thanks,
Scott

There was no" voltage drop spike".
What happened was at 9: 01.2, a message appeared that read:
Aircraft battery level low. Return to home promptly (Code: 1B030014)
At the time, the drone was 3.5 miles away and the battery levels were quite normal.
But Low battery RTH was initiated because the drone was about to go past the point from which it might not be able to make it back home.
This is 100% normal behaviour.
The drone returned with the battery level at 24%.
