Nikon MB-N11 is a battery grip for
Nikon Z 7II and
Z 6II full-frame mirrorless cameras. It can accommodate two batteries and has mirrors key buttons for vertical shooting.
The MB-N11 is compatible with any combination of EN-EL 15, EN-EL 15a, EN-EL 15b, and EN-EL 15c batteries. It can also be used with a single battery in either chamber A or chamber B. It will drain the battery in chamber A first, before switching to chamber B: this allows the user to hot-swap the battery in chamber A for uninterrupted shooting, perhaps in certain videography / time-lapse scenarios.
It is also possible to check the battery levels directly with the MB-N11 battery grip.
Naturally, the MB-N11 comes with a tripod mount. It can also be used to charge the batteries when connected to a power source via its USB-C port.
