My P2 is about 3 years old along with 3 batteries all bought at the same time. THe drone has seen light use but has had a mishap or two - nothing major. The batteries charge to 100% but none of them give me more than 3 minutes of flying time before they're down to 1.5 LED's and the drone returns home. If one died I'd think it was natural but all three dying at exactly the same time in the same way seems too coincidental. Any ideas? I've taken a screenshot of a fully charged battery in the drone.
