When I flew a battery today with my P3, I got Overcurrent During Discharge during a second on the screen. The voltage went to 0 but then resumed normal. I came down for safety, but the battery flew fine. It was also inserted fully.
What does this mean? Should I replace the battery at once?
The battery has been used about 30 times.

In the battery history, I see "Overcurrent during Discharge" and "Time to discharge". What does that mean?
