Hi everyone, yesterday I bought the fly more combo for the mini 3 pro from Amazon.  Going to insert the batteries to upgrade the firmware, I realized that they were completely discharged (the drone would not turn on).  Now, as far as I know drone batteries should never go completely flat because they could get ruined.  Is that a problem?

Hello, there. Sorry for the inconvenience. May we know if you charged the battery successfully?

Yes, I charged both batteries

You have to activate the batteries by connecting them to a charger. Do you recall how many lights were flashing when you first connected the charger?

Yes, only one light

They were in hibernation mode from the factory.

Sorry for the late response. The batteries of some products will enter hibernation mode when shipped out from the factory for long-term storage. A battery in hibernation mode can be woken up with a charger, but not with a charging hub.
