Hi Everyone,  I'm new to the drone world and recently picked up the Mini 2.  So far I'm very happy with it, with one exception.  Every time I have to do a battery swap, my next flight (immediately after the swap) I'm limited to 48m distance and 30m height.  I originally thought it was because I was in a warning zone, but yeterday I went well outside of any zones and had the same issue happen.  I can fly unrestricted on the first battery, but when that one dies, and I swap it out and try to fly again, restricted.  This has happened on 4 different days for me.  I went through the user manual and didn't see anything that would help, and I've searched on line, but also found nothing.

Anyone else experiecing this?  Am I missing a key piece of info on the Mini 2?  Any help appreciated.

Sounds like you have the payload mode set to on ?

Next time you try and get this, I’d recommend doing a screen recording and share that here so that we can see what you see. Quite frequently this makes it far easier to provide a definitive answer rather than just a guess.

Have you attached anything else to the drone, like prop guards?

Hi DJI Stephen, we appreciate your help.  I was also impressed with DJI Support helping to resolve my own Mini 2 issue, which is being resolved by returning the drone for replacement.  However, the suggestion that the user refresh the DJI Mini 2 firmware is not helping much, given that the current DJI Assistant 2 (Consumer Drones Series) V2.1.0 supporting the DJI Mini 2 does not provide this option.  I assume that this option will be provided in the future.  Related to this, I was able to update the firmware twice on my Mini 2 using DJI Fly.  I don't know why it let me do it twice, but it just did.

Thanks everyone for the suggestions, weather has stopped me from trying anything last night and it will continue to keep me grounded till Thursday.  I don't have any prop guards or any other items attached to the drone to make it register as heavier on take off.  It doesn't show P Mode when flying, but I haven't gone into the settings to see if it's been turned on, while flying.  I'll see if I can refresh the firmware, or at least run an update.  And next flights I'll capture some screen recordings to post.

It sounds like a firmware refresh on those two batteries could remedy the problem.

Power the Mini 2 with the suspect battery and controller on indoors, ensure your phone has a internet connection.  Open the App and ensure the Splash Screen is showing (not Camera View), wait a few minutes and you may see a Firmware Update for Battery appear as mentioned by ABI above.  DJI Assistant does not work, I’ve seen numerous reports on this and yet DJI Moderators continue to advise to use it!?

Hi everyone, thanks for waiting patiently. There was a break in the weather and I got out to test. I updated the firmware on all batteries before heading out. I flew without issue on a full battery till I got the Low battery warning. Landed, swapped batteries and was then restricted to 30mh and 48md. Screen recording located below. I did not have any guards or other accessories on the drone.

Hi kcahill76,

Interesting case....

There is a 30 meter limit and distance limot in the manual.
Has to do with low GPS reception.
In your video at start the GPS is bad....

Try to land in this limitation situation, shutdown rotors and start rotors and fly again...
If it always the same second battery to give this limitation?  (try to start a totally new flight with this #2 batt first)

cheers

Hi kcahill76,

Interesting case....

Thanks, but it doesn't matter the battery I used, I've swapped to my third battery and had the same issue.  Also if I wait about 30 minutes, I can fly with no restrictions on the same battery that originally caused the problem. And sometimes, after landing and taking off again, it works, which I did try 3 times on the attempt yesterday, and wasn't successful.

I've tested this well outside of any warning zones and had the same issue.  And I can fly in this zone on the first battery, with no issues, until I do the battery swap.

i know you can....you told me so   but your MM2 thinks different.
So what is changing after a batt swap?  MM2 is switched off and on again. (quickly done)
But in in your video i see first bad GPS signals, wich is bit weird as MM2 don`t need more time to search for sats as it knows where they are....

What if you swap batt and wait longer time for take-off?

well  curious what is in the log about this malfuction.

cheers

I am very new to drone flying so forgive me if what I suggest is rubbish, but when you insert 2nd battery, can you then go into settings and adjust height and distance parameters.
Excuse my inexperience if this has been tried already.

The height and distance are set well beyond the limits I hit, but always a good thing to check!

Hi,

Your flightlog shows that you are flying inside a Warning Zone bc of the airport.
But DJI zone map shows that you are outside that corridor.

Even so, doesn`t give an explanation that the limitation is there only after a battery  swap.

if you have flown at other locations too with the same result....imo tech wise a battery has nothinbg to do with GPS positions, yes / no in an warning area.

Hope that DJI can help you out.

cheers

Hi DJI Stephen,  I've uploaded a video of a screen recording that I've taken after swapping batteries and getting the flight restrictions.  I've also included the log files for that flight.  I'm hoping you can take a look and let me know your thoughts.

Interesting case. I have sometimes this issue with a Mavic Pro in good conditions (good GPS signal, no warning zone, no limitations in the app etc...). I've no explanation. Sometimes it disappears after an ON/OFF.
