DJI When are you going to fix the battery serial number issue? Some of us use this to monitor the health of our batteries and now we can't!

I might have missed this one but what is the battery issue?
Does it effect the p4p?
Does it effect flight performance or safety?
Not trying to take over your post just concerned there maybe an issue im not aware of.

Could you be more specific of the battery SN issue? I'd like to check what can I help.

Since the two most recent GO updates on iOS the serial number for the batteries used in flight have been stripped out of the flight data. I use this data to check on the health of the various batteries I use. Since the data has been taken away - there is still battery data, but there is no way to identify which battery I was flying. This has helped me in the past identify  a battery with a weak cell that I retired. It is a safety concern and part of my maintenance logs as well. Other apps like Kittyhawk and Airdata also use this data.

Have you tried numbering your batteries with a pen or sticker to keep track of which battery is which.
I know that doesnt solve your problem but at least you can easily identify each battery.

I have them all numbered, however in the data stream provided by the flight logs - there USED to be each batteries serial number transmitted as well. Now that is not there anymore..

I have checked the device on my hand, the battery SN is available in DJI GO 4. Could you post the screenshot for double check?

Yes the serial number shows up in the app, but not the flight data created by Go in its latest version.  This data has been there for a long time but now it is gone.

On a similar note: I was truly expecting iOS Go app to get Battery Life returned for us.

Android version still have theirs.

Why can't we get this Important parameter put back in the iOS app for us?

@DJI-Ken was supposed to look into this, but now that he has been vacant from his forum mod personality...

Double checked, which software do you use to review the flight records? We can not ensure this on the third party software, please check the error message of battery in App if something goes wrong.

This has nothing to do with third party software.. It has to do with removing data output from DJIGo that has always been available. There is no reason for it - the data has always been there in the past versions of GO and now it isn't.  I don't understand the reasoning behind it - is DJI going to start taking away more and more data from us to see with newer versions of DJIGo?

"is DJI going to start taking away more and more data from us to see with newer versions of DJIGo?"
Yes it seem so, has been going on since this summer, Smart RTH toggle, Gimbal Yaw adjust, HDMI overlay toggle and possibly more i don't remember right now.
I am still convinced their FlySafe team need the space in order to add up their (often false) No Fly- and various Warning zones.

I have the same issue.  I have numbered each of my 4 batteries, but when I review the logs, it goes to "Default".  I keep track of it by hand in a separate database, but it's work.  I shake my head when I review the logs and my drone has forgotten which one it was.  Also, it has forgotten the number of times it was charged.  I keep very accurate records and I know, but something changed in the last firmware and it no longer is accurate... It's not terrible... it's only off by 5-6 charges (depending on the battery)... but it is wrong.

As far as I know, the battery SN can be found in DJI GO for now. I'm not sure what are you referred exactly, sorry about this.

Sorry, but the point is that it was taken out of the data in the flight logs. I can look at the battery and the GO app when I am flying, but if I am looking at my flight logs and want to know which battery was being used that had a cell reading low compared to others for a particular flight and that battery is a safety risk - that data is no longer included in the flight logs.. To me this is a safety issue and one that should be addressed. It is NOT in the flight logs anymore. This has NOTHING to do with third party software.. It has to do with omitted data - data that can spot performance trends that could potentially lead to failure of a MAJOR component of flight.. The battery - the heart of the aircraft..

Unfortunately it doesn't look like they care at all. I really don't want to jump on the bandwagon feeling this way but it is obvious they don't care. In DJIGo's last update they said that they would take away the warning when you go into sports mode that pops up, but it is still there.. Oh well - guess it's just what we have to deal with.. smh

In earlier versions of the flight record it used to record the battery serial number. The current flight records do have data on the battery including the voltage in each cell throughout the flight, temperatures etc,  but the actual battery serial number is no longer there. We know that the battery serial number is displayed in the GO 4 app while the drone and RC are turned on so it should be easy for the techos to include that serial number in the flight record again.

I have come to accept, that DJI is thinking bigger than just the Phantom 4 crowd.  The last "Big" upgrade to the phantom 4 was the color black.... (WOW!)   I don't like it, but I do understand it.  They are focusing on higher end lenses (can you say higher $$ margin?)  They just released a subscription ($100 per month) to play Drone Airport... they are thinking big.  I understand this.  I wish that my drone was more in line with what they were doing, but it's not.  The phantom purchasers are just the cash cow, paying for the advanced and cooler things in other areas.  Wish it was different,,,,, but it's not.

Actually I think the Phantom 4 series has just been put in the bin. There have been several firmware updates to the Mavic and Spark and numerous GO 4 app updates for the Spark, a few for the Mavic and nothing for the P4 series. There seem to be numerous gimbal issues and half the population is running the beta firmware but still no formal firmware update.

I do this as well but does not fixed the issue of the data being imported to DroneLogBook with no serials.

Hi, would you be able to show me where on the Go app you can see the serial number of the battery, I have the Phantom 4 version and I can't see the serial anywhere, at least if I found it this way I could match it up manually to my labelled batteries and then input tis manually in DroneLogBook which is a real pain as it used to be done automatically.

Cheers

Hi

Not sure it would be actual anymore, the post above sounds like your problem is solved but this picture should give a clue of where to look for batt.s/n.
