Mavic Air 2 Batteries, The Good, The Bad, The Ugly

[Pappy]

I have read some posts about Mavic Air 2 battery failures. It may be good to keep track of batteries which have not experienced any issues as well as those that have failed. If you care to participate, please post your battery's S/N, Mfg date found in Fly app (optional) and whether the battery is "OK" or has failed (reason optional). The data you provide will be added to a GSheet I have setup for you to view the latest data. This will help others in identifying potential battery issues.

Why is it I can’t open any images that are attached to posts in this forum. I’m on an iPhone.

If you are trying to view the battery picture, then you may not be logged in to mavicpilots.com. When I tried from my Android phone (I do not have access to iOS) I could open the spreadsheet, but not the image because I was not not logged in.

All 3 of my MA2 batteries in the Combo pack were slightly swollen from day 1. No failures, but swollen batteries can lead to more swelling during use, from additional heat, potentially leading to a disconnect and a crash, leading to battery "failure." That has been the issue with all M2 batteries, many of which have started swelling starting 12 months after date of manufacture. Are you tracking swelling, as well, on MA2 batteries?

I doubt there will be very many failures documented. Swelling would be a far better indication of potential failure.

I may be out of line here ,
But isn’t this a manufacturers task to collect data from batteries that get returned due to whatever fault the battery is suffering from , warranty claims etc .
They then pass the findings onto the company that produces the batteries .

The list isn't just for failures. Could you possibly provide the S/N of the sollen batteries and I'll add "Swollen Slightly, New" to the Comments column.

Thanks for submitting your battery info. It's been added to the list.

The list is for any condition the battery is in - no issues, swollen, burnt hole, melted, etc.

I'm sure there is a defect list INTERNALLY to DJI which the public will NEVER see, hence the need for a public one. With such a list you could then determine if the batteries you have may have potential catastrophic problems or you should be good to fly. From listing thus far, it looks like the first 7 characters of the S/N are the batch #.

I've stopped using the charging hub, after noticing the fully charged battery ( first in line up) display all 4 leds momentarily, whilst the second battery was well into it's charging cycle.
It might also be prudent to monitor the Battery temperatures, every so often in flight. I'd start getting concerned iff they were going over 45c

The batteries are not charged in order of line up, but based upon the one with the highest charge to the least charged. Any time a new battery is added to the hub, all four ports must be checked to redetermine which battery has the highest charge, including those already charged, to determine which battery should now be charged first. Any battery at 96% charge (or higher) will be ignored.

You'll end up with every new MA2 battery on the list, as I believe they are all slightly swollen when new, which is why DJI automatically bleeds them to 96% after 24 hours and to 60% after 5 days, and hibernates them if not charged within 24 hours of depletion. They also now have metal clips on the sides and check for complete clipping before launch, because of the slight swelling, which requires more attention than a completely flat new battery, like the M2 batteries were when brand new..

Mine are?. I can swop the order around and it always charges the one nearest the charger first and not the battery with least charge, which is why I don't use it. As you say it should charge the batteries according to state of discharge.

Mine works correctly. It does not charge the one with the least charge first. It charges the one with the highest charge first. If I add another battery to the hub with batteries already on it, the charging of the battery currently being charged is momentarily suspended until all connected batteries are re-polled, and then the one closest to full charge starts charging, which may or may not be the one that was previously charging. Goal is to get you a fully charged battery as quickly as possible.

Battery date can be found in the Fly app. I no longer have 1.1.5 version of the Fly app, but in version 1.1.6 it's under the "Safety" tab. The S/Ns have been entered into the spreadsheet.

I like that idea a lot!

Just an idea: wouldn't it make sense to add also the charging cycles the battery has had when listed in your sheet?
I am just thinking of the possibility that the (exterior) condition of the battery might change with more cycles...
