What Should You Know about V-mount Camera Battery

If you’re serious about filmmaking, you already know how critical power is to your shoot. A dead camera mid-scene can ruin a perfect take—and that’s where the V-mount camera battery proves its worth. This powerhouse of a battery isn’t just for high-end productions; it’s become essential even for indie filmmakers and content creators. Whether you’re powering a cinema camera, monitor, or accessories, the V-mount keeps everything running smoothly. Let’s dive into why these batteries are taking over production sets around the world.

What is a V-mount Camera Battery?

A V-mount camera battery, also known as a V-lock battery, is a professional-grade rechargeable power source designed for use with high-draw equipment like cinema cameras, field monitors, wireless systems, and LED lights. Named for the V-shaped mounting mechanism, these batteries lock securely into compatible plates or rigs, ensuring stable and consistent power delivery.

Unlike standard DSLR batteries, V-mounts are designed to last hours—sometimes a full day—on a single charge. Most models feature multiple D-Tap and USB outputs, letting you power your entire camera rig and accessories with a single unit. This all-in-one power solution is especially helpful during long shoots in remote locations where swapping out batteries every hour is impractical.

Why Use It to Power Your Camera Gear?

So, why should you choose V mount camera batteries over traditional ones? 

Firstly, a large V mount camera battery offers maximum capacity—perfect for situations where you can’t afford to run out of juice. Whether you’re shooting a full-day wedding, a live event, or a long interview session, a 190Wh or 260Wh battery can be a lifesaver. They reduce downtime caused by frequent battery changes and help maintain continuity in your shoot.

Then there’s the convenience. With multiple outputs and a centralized power source, cable management becomes simpler. You’re no longer juggling different chargers, mounts, and battery types. Most professional rigs have a V-lock plate built-in or can be equipped with one, making integration seamless. And finally, their build quality is robust, designed to endure harsh shooting conditions from cold mountaintops to hot desert sets.

What Cameras Use V-Mount Battery?

Besides using a V Lock battery for BMPCC 4K, many other cameras also support V-mount power systems.  The list is long and includes most high-end and mid-tier cinema cameras. Here are some popular models:

• Blackmagic URSA Mini and URSA Mini Pro

• Canon C300, C500, and C700

• RED KOMODO and DSMC2

• Sony FS7, FX6, FX9, and Venice

• Panasonic EVA1 and Varicam

Even mirrorless cameras like the Sony A7 series or Canon R5 can use V-mount power via dummy batteries or D-Tap adapters. It’s all about matching the battery output and connector type to your gear.

How to Connect V Mount Battery to Camera

Connecting the V mount battery to the camera is easier than you might think. 

First, you’ll need a V-lock battery plate compatible with your camera or rig. This can be mounted to a cage, tripod, or shoulder rig. The plate acts as a bridge between the battery and your camera, often featuring D-Tap, USB, and other outputs.

Next, use the correct cable—usually a D-Tap to DC or D-Tap to dummy battery—depending on your camera’s power input. Secure everything tightly, check the voltage compatibility, and power on. Some plates even include circuit protection and OLED screens for voltage monitoring, giving you complete control.

Conclusion

Whether you’re using a V-mount battery for a Blackmagic Cinema Camera or building a rig for a multi-cam setup, one thing is clear: reliable power matters. A V-mount solution helps you shoot longer, stay organized, and avoid unexpected shutdowns. If you want your gear to work better and your shoots to run smoother, it’s a smart choice for any serious filmmaker.
