Electronic 1st Curtain H+ Burst Issue
I had to send my R7 to Canon Service for the second time recently, after returning from a three-week trip to the Midwest. I was having three issues: the camera ignored which SD card I selected for saving photos to (and was inconsistent with its own selection), the shutter would occasionally continue shooting for several shots after I removed my finger, and electronic 1st curtain shot at about 7 FPS even though I had H+ selected for burst rate (should have been 15 FPS). I got it back about a week ago. They ended up replacing the circuit board. I've shot about 500 photos since it was returned, all in H+ and electronic 1st curtain. So far there have been no issues with the SD card selection and the runaway shutter button, and mostly with the burst rate. I had an issue yesterday that ruined the streak.
I have only one LP-E6NH battery, but I have a bunch of LP-E6N's from shooting 7Ds and 7DIIs for the last ten years. After shooting for about an hour yesterday morning and the previous several mornings, my LP-E6NH needed to be charged, so I swapped it out for one of the LP-E6Ns. A photo opportunity presented itself, so I took the camera outside and began shooting the Carolina Wren that had shown up (having changed nothing else). The camera again was slowed to about 7 FPS. I was dismayed. I tried cycling the camera off and back on with the same result. My immediate thought was that the new circuit board had gone bad and the camera was going to have to be sent back for a third time.
Before calling Canon Service, I ran through the questions they were likely to ask. Since I had swapped batteries, I knew they would ask if I was sure the battery wasn't the cause, so I replaced the fully-charged LP-E6N with the depleted LP-E6NH and tested it again. To my relief, H+ was restored to 15 FPS. This morning I tested three other LP-E6N batteries, and all worked fine. At least three of the four batteries are the same age and have had roughly the same degree of usage, including the one that caused the problem.
I would have thought that any compatible battery would work as expected, regardless of the age, with older batteries going dead sooner. Apparently, at least in some cases, that's not true. I hope my experience will save someone out there in the community the expense and inconvenience of unnecessarily sending their camera in for service.

This is to be expected I think, others have reported issues with none-H batteries on R7 and R6.
Fyi: I was talking to a chap in a bird hide the other week shooting mirrorless Nikon. He reported similar issues if I remember correctly.
I would recommend to all to get a spare H battery.
