Good day. I have just added a brand new battery to my Air 2S combo pack. After fully charging and installing there was naturally an FW update that went smoothly. Upon the aircraft restart, the Fly app said FW updated successfully but a module is inconsistent and it will be updated to eliminate that. The rear LEDs (status indicators) flash red upon connection when on this new battery, but flash green with the original 3 batteries. I have tried flying with this new battery and it flies normally.


The FW inconsistency message went away on the first restart but the LEDs flashed red with this battery. What am I missing?

Check your drone with DJI Assistant 2, to check that the drone FW is up to date as well

I have checked with the fly app and all shows updated but I will check with the Assistant 2 as well. Thanks for the suggestion.

Hi there. Thank you for reaching out and we're sorry for the trouble. You may refer to the suggestion of ReproRetro on post #2 about plugging in your aircraft with the said battery on it to your computer using the DJI Assistant 2 software and please check for updates or refresh your firmware and check if the error message is still showing on the app. Please keep us posted. Thank you.

Weirdly, without doing anything the issue went away when I powered on the drone and RC normally this afternoon. I am considering it a one-time glitch and looking forward to adding more batteries in the future. Thanks to everyone.
