Just a heads up, battery firmware went thru an update.

I tried all three batteries but didn't get any messages in DJI Fly when connected through the controller to the Mini.

I don't think the battery have firmware update cause it using 18650 battery and no PCB board inside not like other dji smart battery.

I just updated the battery firmware. Do I have to update each battery since I have the fly more combo? I inserted the other two battery and it did not notify me to update the battery firmware just for the one battery.

I had the update for 2 out of 3 batteries...

I updated all 3 off my batteries in the fly more.

Wow good find but seems very risky to me.
Regarding updates, not sure why only two of my 3 batteries did the firmware update...
