Meaning in either the .txt or .DAT log files....... or somewhere else perhaps in the Go4 App.

This relates to either the Pro or the Zoom.
I have a number of batteries and sometimes get the ''inconsistent firmware'' or  such messages and it would be convenient if I could check the battery firmware version.
Thanks

Hello there Sean-bumble-bee. I am sorry for the trouble this has caused and thanks for reaching out. Kindly please check the intelligent flight batteries of your DJI Mavic 2 Zoom as these batteries might also require an update to match with the said DJI drone . If you have not tried also, we recommend updating or refreshing both the said DJI drone and remote's firmware via the DJI Assistant 2 to see if that helps and to see if the issue will still persist. Thank you.

Thanks I know how to update them firmware but that was not my question.

My question was and is, is there a way that I can find out what the current BATTERY firmware version is?

With regards to the video, were the updates shot using timelapse photography? The updates I have done take a LOT LONGER that those shown.
