Extended battery grip for Sony A7S III A7R IV A9 II

The Green Extreme VG-C4EM attaches to compatible Sony mirrorless bodies and holds up to two NP-FZ100 batteries, effectively doubling available power for long shoots or remote work. Vertical shooting controls and a matching contour improve handling during portrait orientation. Sequential power management displays real-time status while maintaining performance at high continuous rates.

Replaces single-battery operation for demanding

Swapping to this grip removes the need to change cells mid-session, which is valuable for event coverage, wildlife waits or video work where interruption costs the shot. The jump is worth it when a day's workload exceeds one battery or when vertical handling matters. Shooters who rarely drain a single charge or who prioritise the lightest kit will not gain from the extra bulk.

Limited to NP-FZ100 cells and three camera models

Only the listed Sony bodies communicate fully with the grip's electronics, so other models lose vertical controls or power reporting. The twin chamber accepts one or two batteries but cannot charge them; depleted cells must be removed for external charging. No USB or alternative power input is provided, so extended off-grid use still requires spare batteries and a separate charger.

Questions about this item

How does the VG-C4EM attach to the Sony A7 S3, A7R IV or A9 II?

The grip mounts into the camera's battery compartment after removing the cover, then secures with the integrated tightening wheel — the step many miss is fully seating the electrical contacts before locking the wheel down.

Does the grip accept one or two NP-FZ100 batteries, and how does it switch between them?

It holds one or two NP-FZ100 cells and draws power sequentially, showing the remaining charge for each battery on the camera's own display in real time.

What part of the VG-C4EM is most likely to need replacement after heavy use?

The battery-door latch and the contact pins inside the twin cell chamber see the most wear; keeping the contacts clean and the latch free of grit extends their service life.
