I saw the following link

I have the gomadic battery pack (which, by the way, does not look anything like the picture on the gomadic web site), and it works with my Edge 800. Make sure that you update the firmware on the Garmin unit to version 2.1, some of the issues related to the unit not being usable while charging have been fixed.
