Are you a videographer or filmmaker working with the Sony FX3 camera? If yes, you’re likely aware of the need for a dependable power source to keep your camera running smoothly during shoots. A V-mount battery is one of the top choices for powering your FX3, offering large capacity and enduring performance, making it perfect for longer filming sessions. This article explores why and how to use a V-mount battery for Sony FX3, along with other recommended accessories to enhance your shooting experience.

Why go for a V-mount battery for Sony FX3?

Firstly, V-mount batteries have a larger capacity compared to the standard one that comes with the Sony FX3. The FX3’s standard battery gives you about 95 minutes of actual recording time and 135 minutes of continuous recording. While this might be enough for short shoots, it’s not ideal for longer filming sessions. That’s where a V-mount battery, like the Moman Power 99, comes in. Its 99Wh capacity can double your recording time to around 4 hours. Plus, it’s much lighter and more affordable than traditional high-capacity options, costing under $150—a perfect alternative to the standard FX3 battery.

In addition to more power, V-mount batteries for Sony FX3 offer excellent flexibility. They are compatible with a variety of devices, from your camera to LED lights. This means you only need one type of battery for all your equipment, making your setup simpler and easier to manage.

This flexibility also extends to nearly all gear commonly used during shoots, such as monitors, wireless follow-focus systems, or servo lenses. They come with multiple outputs, allowing you to power several devices at once with just one battery. This makes your work easier by reducing the need to manage multiple battery types, and it's a big time-saver for busy professionals.

In addition to the SONY FX3, the Moman Power 99 V-mount battery is compatible with other professional cameras.
