Just got the grip. I noticed that only one battery is used all the time. On grip of the 7D it used the bateries alternatively.
I checked with a single battery and it worked from both posisions. I also swiched the location of the bateries and it uses a batery on the first lacation, not batery related.
Is this the way it should work?
