hello, everyone

Soon I notice a difference between the three cells on the battery. Is that a problem

No this is normal, if you notice a large difference between cells then that would be a concern.

thanks for the reply
How big the difference should be - from - to -
Thanks

I agree that it's not likely a problem at this point.  If it were an older battery with dozens of charge cycles it might be something to watch closer.  If I had those readings I would do a full charge (after battery has cooled), fly to 10-15% for 2-3 more flights / times.  I'd record the voltages/cell after each flight and see if the difference increases.  If it does, send the information to DJI via support CHAT and ask their advice.

thank you very much for the answer.I will listen to you and do what you have said.I just do not know which program to record battery voltages

You're welcome!
No program necessary.  Just take a screen shot as you did for your post.  

Hi Yordan, may I confirm that is there any error message on your DJI GO4 APP? Please keep close attention to the notification from the app, if there is an error of the battery, there will be a notification. Thanks!

Hello Diana,
for the moment I have no error notification,I will follow in the future
