D810 battery grip increase.

[robmac]

Hi all
I’ve had a D810 for years and just acquired a Nikon grip for it.Already had the larger battery from when I had the D850 with its grip but I thought it allowed the D810 to go from 5 FPS to 6?
I know it does in crop but I’m not interested if that only FF.
Any help appreciated
Thanks

My D810 with run faster with the grip but with the Battery cradle in with the AA X 8 in it, well it feels faster BUT its very heavy with 8 Eneloops in

You only get an uplift in crop modes
