Question about Hähnel ProCube 2

Good day
I use the charger regularly with the Nikon batteries EN EL15, EN EL 15A and EN EL 15 B (D850 and Z7). I am very satisfied! I wonder if it is compatible with EN EL15C, as EN EL15A and B are both just improvements of EN EL15. EN EL 15C is probably another improvement, but I'm not sure. Maybe you can compare the items on the corresponding Nikon accessories page. Greetings Iv
