Hi,
I bought my mavic air a month ago with 3 battery included.
Now when I try to charge one of them the light of the charger give become red / battery error.
What should I do?

Hi there, just to verify, the other two batteries are charged well when using the same charger, right? If yes, please kindly provide us with a short video of your operation, we'd like to check the exact status, thank you!
