I recently performed the latest software upgrade on my Inspire and remote but I keep recieving a upgrade battery message!
I have three batteries total so do I need to perform a download to the Inspire with each battery in it to complete the battery
upgrade?

No, just install each battery into the Inspire with the BIN file in the camera and power on and then do that to each battery.

I get the same message Which BIN file?  I was successful upgrading the RC and Craft/Camera with the appropriate FW.  Thanks

I partially answered my question. Put the new  BIN file on a SD card, inserted, turned it on and then the same..."battery needs upgrade" . No beeps from the CAM indicating its updating.  Looked for various 'button's'to push to .."start battery upgrade, etc".  What am I doing wrong?  How do I start the upgrade?  Thanks
