Green Extreme BG-E21 Battery Grip for Canon EOS 6D Mark II

Extended shooting time

The Green Extreme BG-E21 battery grip attaches to the Canon EOS 6D Mark II and accepts one or two LP-E6N batteries, effectively doubling the camera’s operating time. It also includes a magazine that lets you power the camera with six AA cells for added flexibility. The grip maintains full communication with the camera so all controls and metering work exactly as they do on the body alone.

Vertical handling and stability

A built‑in vertical shutter release, command dials and function buttons replicate the primary controls, making portrait and event work steadier and more comfortable. The rubberised surface matches the camera’s finish and provides a non‑slip hold in any orientation. Because the grip forms a seamless extension of the body, the centre of gravity stays balanced even with heavier lenses attached.

Dual power options and sustained speed

Switching between LP-E6N packs and AA batteries means you can keep shooting when proprietary cells run low or are unavailable. The grip supports the camera’s high‑speed continuous mode at a consistent six frames per second, so burst performance does not drop off during extended sessions. This combination of power redundancy and unchanged frame rate suits long-form video, time‑lapse and all‑day event coverage.
