Have been doing my 3 monthly update and battery charge of all my DJI Aircraft.

I found the new FW version for the Air 2S does a battery upgrade. I dont know what the upgrade does but I would assume its a positive thing.

My Air 2 did not need a FW update or Battery update.

I use 8 batteries in total for the Air 2's and swap between them. I updated all 8 and tested them in the Air 2.

The updated batteries had no issues in the older aircraft.

Just FYI

Good to know and many thanks for sharing.  

Hi, bjr981s. Thank you for reaching out and sharing your experience with the new update. You're absolutely correct, no update yet for Mavic Air 2. As for the Air 2s, the recent update was to add the support for the following information below:

• Added support for United States RID requirements.
• Added support for DJI RC remote controller.
• Added support for Expo Curve settings in Cine mode.

Thank you for your valued support.

How do we update batteries?

I've never had to update the batteries. And I've owned and been flying this thing regularly for almost 2 years, and have done all the software/firmware updates.

I've read numerous times about people updating the batteries, and always wonder if perhaps they're in the wrong forum? Or maybe I'm missing something? I had to update the batteries once with my old Mavic Pro, but never with the Air 2S.

When you use the Assistant 2 for PC and Mac to update FW and it has just completed the update, swap the battery for another and check the FW status again.

If it says incompatible FW found, it will ask if you want to update the FW again. Say yes and it will update the FW on the battery. This is a quick battery only update.

The only way that is possible is if you only have one battery.

If a battery FW update is required as part of the FW update it will update the Air2S and the battery in one pass.

If you have more than one battery and an update is required you need to swap the battery and check again.

If the second display of the FW does not say incompatible FW detected then there was no battery update.

The Air2S has had battery updates multiple times since launch.

The last current update requires a battery update and the cycle through all your batteries.

I believe another way to check is to use the Fly app and do a FW check. It will then identify incompatible FW if the battery has not been updated..

Aha! you are correct - I just updated 5 batteries. I really need to amend my previous post, as though most of it is technically correct, it all gives the wrong impression. I think the second sentence of the second paragraph is the most correct statement.

While it is true that I have 6 batteries, and have been flying with them all for almost 2 years without updating most of them, I'm also really anal about how I use them, and they're numbered, and I always have battery No. 1 in the drone at home when I do updates. So that battery has been updated regularly. The other ones I only use when I'm out flying, and apparently the Fly app doesn't care if you use an updated battery and doesn't complain. So now that they're all updated maybe I'll get better flying times or something.

Great good to see you have your problem solved.

Incorrect or incompatible forward can lead to an adverse event.

Like battery remaining is 50% then it goes down by 1% per second. This was reported in a thread here some time ago.
