Mavic air crash

[Jcastro1836]

Yesterday I was flying my mavic air and suddenly went from 56 % battery to 0. Last spotted in a very swampy area? Anyone ever experience an issue with the battery doing something similar?

when you find it i think the battery will be missing it sounds like it came out during flight

 

[Jcastro1836]

I’m going to try and look for it again today

Do you have the flight logs from your mobile device? If so, please post them here and that may give you some answers.

Did you takeoff with 100% fully charged battery?

 

[old man mavic]

another scenario that can cause a sudden voltage drop, is a cell voltage imbalance when the low voltage cell reaches a critical point

Definitely started at 100 percent battery. My flight history shows it drop from 54% to 0 in aBout 4 seconds. Tried to upload the video here but only lets me uploads pictures.

@Jcastro1836 .... Post the video on your YouTube (or other media place) channel. Tap the “share” button and copy the link (usually automatic). Post the link as text in your post. Then it will be there as will a preview pic.

Indeed I have! See MA battery failure scare for details.

Possible, perhaps, but not too likely. The MA has safe latches, and if you fail to adequately seat them, the bird just won't fly. Battery drop-outs are pretty rare with the MA on that account.

rare yes but not impossible battery puffing and violent stops and manouvers flying in sport mode can and have caused batteries to fall out

The flight logs would be far more informative than the video:

Just feel like this doesn’t show how the battery jumped from 54 to 0

 

[MAvic_South_Oz]

Yes, no videos can be uploaded directly to the site, must be done via other video hosting site and linked.
Understandable with video sizes and storage.

If you want to show us the video, upload to Youtube or Vimeo etc, make sure the video is marked for viewing with the link, or made public (anything but private), and post the direct link in your reply here.

Go the the Phantom Help link for sar104 post and do that, post the page link here.
A lot of extra info can be gained in most cases by the flight analysts here.

Not the proper flight logs we are looking for...

That's not the flight log - that's just a list of the warnings that were recorded in it.

@Jcastro1836 . . . from post #11, do this and there will be a proper look at the problem.
