Compatible With

• Select Sony L-Series / NP-F compatible devices
• Field monitors, on-camera lights, wireless video systems, and accessories that accept NP-F style batteries

High-Capacity Power for Professional Production

With a 69Wh rating, the NANO-FMX offers substantially longer runtimes than smaller L-Series batteries, making it a strong choice for demanding shoots where fewer battery swaps help maintain workflow. This added capacity is especially useful for power-hungry devices such as brighter on-camera LED fixtures, production monitors, and wireless video gear used in interviews, events, documentary capture, and mobile cinema rigs.

Versatile Output Options

One of the major advantages of the NANO-FMX is its expanded functionality beyond standard battery-only operation. In addition to powering compatible L-Series battery devices, it includes a D-Tap output that allows users to run external accessories from the battery itself. This can simplify compact rig builds by reducing the need for separate power sources. A USB power option further extends versatility for modern workflows, supporting select accessories and mobile devices used on set.

Compact Form Factor, Larger Capability

Core SWX designed the NANO series to provide serious performance while keeping size and weight manageable. The result is a battery that remains easy to pack, mount, and transport, yet offers the runtime benefits associated with a larger-capacity power source. For creators working on gimbals, handheld rigs, director monitors, and portable lighting setups, this balance of capacity and portability is a key advantage.

Ideal Uses

The Core SWX NANO-FMX is a practical solution for videographers, filmmakers, live production crews, and content creators who need flexible power in the field. It is especially useful when powering compact monitors, camera-top LED lights, wireless video transmitters, audio receivers, and other production tools that benefit from the common NP-F platform. Its multiple output options also make it attractive for users building streamlined camera rigs with fewer cables and batteries.

Why Choose Core SWX

Core SWX has built a strong reputation in professional video power by focusing on dependable batteries, charging systems, and mobile power solutions for broadcast, cinema, and production environments. The NANO-FMX reflects that heritage with a design aimed at real-world professional use, combining trusted battery technology with practical outputs that support modern accessory-driven workflows.

How It Compares

Compared with lower-capacity NP-F style batteries, the NANO-FMX gives users longer runtimes and fewer interruptions during shooting. Compared with larger V-Mount or Gold Mount batteries, it offers a more compact and lighter solution for smaller devices and lightweight rigs. This makes it an excellent middle ground for creators who want professional-grade runtime without the bulk of a full-size battery ecosystem.

Usage Tips

For best performance, fully charge the battery before first use and pair it with a compatible charger designed for Sony L-Series/NP-F batteries. When using the D-Tap or USB outputs, confirm your accessory voltage and power requirements before connecting. Storing the battery partially charged in a cool, dry environment can help preserve long-term battery health, especially if it will not be used for extended periods.

Recommended Accessories

To get the most from the NANO-FMX, consider adding a compatible L-Series charger, spare NP-F batteries for longer shoots, D-Tap power cables for monitors or wireless gear, and a battery plate or mount for integrating the battery into a production rig. A protective case or pouch can also help safeguard the battery during transport between locations.
