I've had my Inspire 1 for 6 months now so pretty used to it and the procedure behind updates.
A few days ago I did 2 updates in a controlled fashion. First. 1.5. Then 1.6
The log indicated success on all the updates (have 4 batteries so multiple updates done)
Upon starting up the Inspire 1 for the first time, I started getting a Gimbal error, saying it had reached the end of it's rotation.
I also got IMU errors. So I recalibrated the sensors, even though it said the IMU was ok. I also reseated the gimbal and eventually the error went away.
So I felt everything was ok.
Took it out for a test flight, low altitude over flat ground.
First 2 batteries (both at 100% charge), got low voltage errors and Inspire 1 landed itself.
NOTE: which is why you test fly after any update at very low altitudes. This was 10ft up max!
Lost confidence at this point and returned home to double check everything.
All seemed ok.
So today went back out for another test flight.
Flight went ok but noticed that repeatedly the battery voltage indictor on the DJI Go app went into the yellow, especially under load, such as a decent acceleration. And a couple of times it went momentarily into the red. No forced landing was issued so cautiously went on. Landed on 50% charge and tried another battery. Same thing. Then 3rd battery. Same thing.
Now, it may be that this is the first time I've really monitored the voltage levels as I'm test flying my Inspire 1 specifically looking for problems. And it may be normal for it to dip into yellow on a regular basis. When I opened up the battery part of the app itself, the cells dipping into yellow were random, sometimes 1, sometimes 3-4.
But as I said earlier, I've flown enough times now and obviously looking at the DJI GO app a lot to monitor the camera, I can't remember seeing the battery voltage indicator go into yellow.
Batteries have been calibrated recently in early December.
Temperature was cool, about 7C indicated, with a slight sea breeze so would say wind chill would be down to 3-4C so nothing extreme but getting close to the 0C limit.
So is it just the degradation in battery performance due to the cold temperatures which is causing this?
Previous to this, we've had a mild winter so flights have been done in minimums of 10C so my hope is it is this and not an error introduced by the FW update.
Any advice would be gratefully received.
