Shoot for longer and improve the ergonomics of your Nikon D850 DSLR with the BG-N19 Battery Grip from Vello. This accessory can hold an additional EN-EL15a battery to effectively double your shooting time, and offers a shutter-release button for easy vertical shooting as well as two command dials, AF-ON button, and Function button. The grip can also be used with an EN-EL18b battery when paired with the BL-5 cover (for up to 7 fps), or power the camera directly via AC with an EP-5B power supply connector and EH-5c adapter combination. It can even accept eight AA batteries when deployed with an alternate battery plate; just make sure to select the correct AA battery type in the D850's setup menu.

To install the grip, remove the contact protectors from both the grip and the camera and align the mounting screw with the D850's tripod socket. An attachment wheel helps ensure a secure fit, while the contact cover from the camera can be kept in a dedicated holder on the grip to prevent its loss. For use with a tripod or monopod, the BG-N19 offers a 1/4"-20 threaded slot at the bottom for easy mounting. Finally, a control lock switch next to the shutter-release locks all buttons on the grip to prevent accidental triggering.
