Tighten the connection between the grip and the camera. Reset the camera and send it back to Canon for inspection. 1. Unable To Communicate With Battery. This is an issue with the BG-11 grip for the Canon 5D Mark III. Canon 5D and 7D both have this issue. The grip works fine with the battery that comes bundled with it.

This grip features integrated control buttons for easily accessing your 5D Mark II's shutter release and camera settings in a vertical orientation. It also gives you the choice of operating the EOS 5D Mark II with up to two optional LP-E6 batteries, or even 6 AA batteries (not included).
I am a pro photographer shooting weddings, and other busy events in addition to studio stuff. Battery life is priority number one and ease of vertical shooting is number two. On number two, as usual and as I was used to having the same on the 5D Mark II's grip before I upgraded to the 5D Mark III, the vertical stuff is done well. NzIyT. 741 823 672 947 383 504 870 228
