Battery Grip Kit for Nikon D850 DSLR - Extended Power and Vertical

In this review the kit is judged as a practical power and handling upgrade for Nikon D850 owners who shoot long events or need better vertical control. The bundle's single biggest selling point is plainly the extended runtime: including four BM Premium EN-EL15 batteries plus a replacement MB-D18 battery grip effectively doubles on-camera run time and reduces downtime. The kit combines convenience and functionality by packing a rapid AC/DC charger and an AA holder option, making it a sensible choice for photographers who routinely work away from mains power.

Key Features

• Extended shooting capacity: The MB-D18 grip accepts an extra EN-EL15 so users can run two batteries and lengthen continuous shooting sessions without swapping cells in the body.
• Vertical handling: The additional shutter release and scroll wheel improve ergonomics and control when composing portrait shots, making handheld vertical work easier and more stable.
• Alternative power option: The grip accepts eight AA batteries via the included holder, which can be useful when lithium spares are not available.
• Batteries with decoded chip: The BM Premium EN-EL15 cells report charge level to the camera like originals, so remaining time is visible without a special charger.
• Rapid AC/DC charging: The included charger brings batteries back to use quickly when mains or vehicle power is available, which reduces downtime between shoots.
• Safety and warranty: The battery kit includes multiple circuit protections and a one-year warranty, offering added peace of mind for field use.

Who It's For

The kit is best for professional and enthusiast photographers using the Nikon D850 for events, weddings, wildlife, or long studio sessions who need longer runtime and better vertical ergonomics. It suits photographers who value being able to see battery charge levels and want a backup charging option that works from AC or DC sources.

It is less appropriate for casual shooters who rarely exceed a single battery's life or those who prefer original-brand accessories for strict brand compatibility preferences. Buyers seeking the highest-end build materials should note that some users described the grip finish as mixed in quality, though functionality met expectations.
