Using a V mount battery for Nikon Z9 is common for high-demand shooting. It provides longer runtime, can power not only the Z9 but also other photography gear, and ensures reliable performance. In this post, we will cover:
- What are its benefits?
- When to use it?
- How to use it with the Nikon Z9?
What are the benefits of using a V mount battery with Nikon Z9?
Compared to the original Nikon EN-EL18D battery, a V-mount battery offers the following benefits to the Z9 camera.
It offers extended power for demanding Nikon Z9 shoots
For high-end mirrorless cameras like the Nikon Z9, dependable power is essential—especially during long-form photography, video production, or hybrid shooting workflows. Using a V-mount battery system allows the Z9 to operate far longer than with standard EN-EL batteries, reducing interruptions and keeping you focused on capturing the shot. This makes it particularly suitable for extended video recording, time-lapse work, and studio or field productions where battery swaps can slow things down.
A V-lock battery can power more than just Z9 camera
A major advantage of V-mount solutions is their ability to support an entire shooting rig, not just the camera body. With the appropriate mounting plate and cables, a single battery can supply power to the Nikon Z9 while also running external monitors, on-camera lights, wireless transmitters, or other accessories. This consolidated power setup helps streamline cable management and keeps your rig cleaner and more efficient on set.
It is built for professional reliability
V-mount batteries are engineered for professional use, offering a level of durability well-suited to both controlled studio environments and challenging outdoor locations. When paired with a Nikon Z9 rig, they provide stable and consistent power delivery, minimizing the risk of sudden shutdowns or voltage issues. Their rugged construction and dependable performance make them a trusted choice for critical shoots where reliability matters most.
When will you need it?
Despite its flagship position, the Nikon Z9 is extremely efficient with the EN-EL18D battery. It can deliver 2,000 photos or more in real-world use, far beyond its official CIPA rating of 700.
For most short-term photographic sessions, the internal battery is more than adequate. A V-mount battery is required for long-duration sessions, hybrid photo-video processes, and situations where recharging is not possible.
It is common to use a V mount battery for Nikon Z9 during these scenarios:
- Long-form video recording and extended takes: Continuous video shooting increases power draw; a V-mount battery enables hours of uninterrupted recording.
- Hybrid photo and video workflows: Frequent switching between stills and video accelerates battery drain; external power ensures consistent runtime.
- Time-lapse and interval shooting: Long-running sequences require sustained power; a V-mount battery helps prevent shutdowns mid-sequence.
- Fully rigged camera setups: External monitors, wireless transmitters, and accessories raise overall power demand; V-mount batteries can power multiple devices from one source.
- Studio, tripod, or static setups: In controlled environments, reliability matters more than portability; V-mount batteries support all-day operation.
- Cold weather or remote locations: Low temperatures and limited charging options reduce battery efficiency; higher-capacity V-mount batteries offer more dependable endurance.
How to use a V-mount battery with Nikon Z9: Two powering methods
There are two ways to bridge the gap between your V-Mount battery and the Z9.
There are two primary methods to integrate V-Mount power into your Z9 workflow. One focuses on maximum reliability and thermal management, while the other prioritizes a failsafe backup system.
Method 1. Using a dummy battery of EN-EL18 Style
This method involves inserting a battery-shaped adapter into the Z9’s battery chamber, which is then wired directly to the V-Mount plate.
⚙️ Gear needed:
- EN-EL18-style dummy battery compatible with Nikon Z9
- D-Tap to dummy battery cable
- V-mount battery
👉 How to:
- Insert the dummy battery into your Z9’s battery compartment.
- Connect the dummy battery to the V-mount battery using a D-Tap cable.
- Secure the V-mount battery to your rig, stand, or tripod as needed.
✅ Pros:
- Preserves USB-C port for accessories or monitoring
- Works with fully rigged camera setups
- Provides stable, continuous power for extended shoots
- Keeps the camera body cooler during 8K recording by removing the internal heat source
❎ Cons:
- Adds cable management complexity
- Slightly bulkier than standard batteries
- Requires a compatible dummy battery and cable
Method 2. Using USB-C Power Delivery (PD)
The Nikon Z9 supports Power Delivery via its USB-C port, allowing you to "charge" and power the camera simultaneously.
⚙️ Gear needed:
- V-Mount Battery with USB-C PD Output, minimum 30W-65W recommended
- High-quality USB-C to USB-C cable, rated for Power Delivery
- Internal EN-EL18d battery
👉 How to:
- Ensure "USB Power Delivery" is set to ON in the Z9 Setup Menu.
- Insert a genuine EN-EL18d battery into the camera.
- Connect the USB-C cable from the V-Mount battery's PD port to the Z9’s USB-C port.
- Look for the "USB" icon or a small charge lamp to confirm the camera is drawing external power.
✅ Pros:
- Features a "hot-swap" fail-safe
- Charges camera while shooting
- Clean and minimalistic for handheld use
❎ Cons:
- Limited by the battery’s USB-C PD output power
- Occupies the Z9’s only USB-C port, restricting data transfer and tethered shooting
- Requires PD-compatible V-mount battery
