2 drones drop out of the sky, none return.

[Meta4]

Just seems odd that so many drones just dropped

How many are you aware of?
How many drones didn't drop?

It's only statistics. Maybe the've got COVID? LOL

Well Three or for just in this group of active participants!

I don't think that's enough to get excited about.
But anyway, sunspots or any other natural phenomena won't do anything to cause drones to fall from the sky.
If there really was something like that in effect, we'd here a lot more about it.

That's not the file that's needed.
Go to DJI Flight Log Viewer | Phantom Help
Follow the instructions there to upload your flight record from your phone or tablet.
That will give you a detailed report on the flight data.
Come back and post a link to the report it gives you.

Or just post a link to the .txt file after you upload to dropbox ar similar.

These are the last 4 flights and I believe the 9_25-03 is the one where it dropped.
Thanks

The flight data suggests problems with two batteries.

Here are summaries of the flight data from the two flights that ended badly.
You can see the battery cell voltages in them.
Critical low voltage level is 3.3 volts and this is usually not seen until late in a long flight.

August 8 at 9:23
Flight record ends at 0:28.9 seconds with the drone hovering and stable at 95 ft.
The battery for this flight might be suspect?
Its cell voltage has dropped more than normal after only 16 seconds of climbing and shows little recovery when following this.
Cell 2 looks sick.

August 8 at 8:58
Flight lasted 1:43 drone taken up to 168 ft
While under load, climbing, Cell 3 falls below critical low voltage level after 0:46.
The drone was hovering after 60 sec
Flight data ends sudden;y with the drone in a stable hover.
But battery cell levels have hardly recovered after climbing.

Could we be experiencing something natural like sun spots or something!

Probably not.

Thanks so much Meta4. the flight at 9:23 is the one it fell out of the sky on. The battery being the culprit makes sense. I've discontinued use of that battery and will turn it in for recycling. I have a few others the same age that I will retire too. Is there any way to "see" the health of the battery? Other than watching the number of times I charge it, how can I tell with to retire an old batttery? Thanks again.
