Yes, no problem at all. Let me first say that when I shoot an all-day airshow, I take thousands of pictures with my gripped body 7DM2 and EF100-400mm L V2. I may only change batteries either 0 or 1 time at most during the entire event. I have two issues with the R7, which prevent me from considering it as a viable replacement for my 7DM2: (1) It appears to have a minimum battery level requirement to achieve its 15 frames per second in mechanical shutter mode, like the R5 and R6 require to achieve their 12 frames per second; and (2) the R7 does not appear to be capable of being fitted with a Canon battery grip. The R7 review at "the-digital-picture.com" noted that the R7 lacks the holes on the camera's bottom that are required for battery grip pins. Note: The R7's electronic shutter does not have this battery level constraint, but the R7's rolling shutter effect appears to be so bad, I would not use it at airshows.
During an all-day airshow, these two issues would likely require me to make multiple battery changes when battery capacity reaches approximately 50% or less and that I carry around pockets full of 1/2 charged batteries due to a mirror-less camera's inherent higher power requirements. This is not practical for me when shooting a fast-paced and dynamic airshow. Thanks.

Thanks for that explanation. I had many of the same concerns when I picked up an R6. Battery life is poorer on mirrorless than DSLR, but its just something you get used to. A useful 'life hack' on this is to run the camera in airplane mode. The battery lasts a lot longer and will get the green H+ mode all the way down to about 13% (on the R6). I assume the result would be about the same on the R7 but until someone tests it we won't know. It also extends the battery life a lot. I can get a fully 3 game soccer tournament on a single battery. That's about 4.5-6hrs of being on the eyepiece, and about 1,500 to 2,000 photos per game. Though the photos don't actually use that much power. Its running the EVF and AF system. If I take 800 total or 6000 total, I don't see that much different in battery life.
Also, just because the little alignment nibs aren't there doesn't mean there can't or won't be a battery grip. There are other examples of Canon cameras like that in one of the R7 threads around here. Though this is another thing we can only wait and see.
But if changing batteries is a big issue, then you'll be in DSLR land for the foreseeable future. I don't use my 5D3 for much anymore, but I do sometimes still think about its super long battery life, comparatively.
