The Panasonic GH5 is a highly capable mirrorless camera widely used for video production, live streaming, and filmmaking. While its internal battery performs well for casual use, many creators turn to a GH5 V mount battery when longer runtime, reliability, and professional power solutions are required.
In this guide, we will cover:
- Why use a V-mount battery with the Panasonic GH5

Why use a V mount battery for Panasonic GH5?
The Panasonic LUMIX GH5 is known for its strong video performance in a compact body, but like many small cameras, it is limited by the capacity of its native batteries. In real-world video production, especially long or hectic shoots, this can become a major drawback. This is where a V-mount battery becomes a practical and professional power solution.
It offers much longer runtime for continuous GH5 shooting
The GH5 uses a small Li-ion battery rated around 14Wh (about 1860mAh), which in real shooting conditions typically gives around 1.5–2 hours of continuous 4K recording on a single battery.
In contrast, a 99Wh V-mount battery has nearly 7 times the capacity of the GH5’s native battery, and larger V-mounts reach 150Wh or more. With that extra capacity, you can run the GH5 for many hours without swapping cells, which is perfect for long shoots or continuous recording.
It allows you to use a single battery to power the entire camera rig
V-mount batteries are designed for professional video setups and typically provide multiple output options. A single battery can power not only the GH5, but also other accessories at the same time.
With one power source, you can run:
- The GH5 camera
- External monitors
- Wireless microphone receivers
- Video transmitters
This simplifies cable management, reduces the number of batteries you need to carry, and keeps your rig cleaner and more efficient.
GH5 V-mount battery ensures fewer interruptions during shooting
On fast-paced shoots or chaotic production days, constantly checking battery levels and swapping batteries can distract you from the creative process. Running out of power at the wrong moment can mean missing an important shot. With a V-mount battery, you no longer need to worry about how much battery life is left. You can focus entirely on shooting, knowing your camera has stable, long-lasting power throughout the session.
What gear do you need to power the Panasonic GH5 with V mount battery?
Typically, you will need:
- A V-mount battery
- A dummy battery with cable
- A V-mount battery plate
V mount battery: Core power supply for long GH5 shoots
A V-mount battery is a rechargeable lithium-ion power source widely used in professional film and broadcast applications. It features a standardized V-lock mounting interface with metal contacts, offering high capacity, strong power output, and a design that allows for fast and easy attachment or removal.
When choosing a V-mount battery for Panasonic GH5, consider the following factors:
👉 Capacity and expected runtime: When choosing a V-mount battery, consider both its capacity (Wh) and the camera’s power consumption. Estimating runtime based on these factors helps ensure the battery can support extended shooting sessions without interruption.
👉 Battery weight and size: When selecting a V-mount battery, weight and size are important considerations, especially for photographers and filmmakers who work on the move. Choosing a battery that is lightweight and compact helps maintain portability while still delivering sufficient power.
👉 Charging ports and output options: It is also important to consider the available charging and output ports on the V-mount battery. Multiple output options—such as D-Tap, USB, or DC ports—allow the battery to power the GH5 as well as accessories like external monitors or wireless receivers. Convenient charging interfaces can also improve efficiency when recharging between shoots.
The Moman Power 50 Touch, for example, is a good choice for the LUMIX GH5.
This 50Wh V-mount lithium-ion battery measures 73 × 102 × 33 mm and weighs about 330g, making it easy to carry on location without adding much bulk to your rig. It features a bright LED status display that shows remaining runtime and battery percentage at a glance.
On the output side, it offers 65W PD USB-C, USB-A, D-Tap, and an 8V DC port, allowing you to power the GH5 as well as monitors or other accessories simultaneously. With multiple smart protections built in, it’s a compact, versatile V-mount battery well suited to extended GH5 workflows.
Regulated DMW-BLF19 dummy battery for GH5: Regulates and delivers safe power to the LUMIX GH5
To use a V-mount battery with the Panasonic GH5, you need a DMW-BLF19 dummy battery (DC coupler). This dummy battery fits into the GH5’s standard battery compartment and allows the camera to draw continuous power from an external source. Unlike a regular battery, it does not store energy itself, but provides uninterrupted power, making it ideal for long shoots, live streaming, or studio setups.
For safe operation, the dummy battery must include voltage regulation. A regulated dummy battery ensures the GH5 receives a stable voltage throughout the recording session, protecting both the camera and your footage.
The connection between the V-mount battery and the dummy battery is typically made via a D-Tap or DC output cable, depending on the battery and cable setup.
By combining a regulated dummy battery with a V-mount battery, filmmakers and photographers can achieve long, uninterrupted recording sessions with the GH5 without worrying about battery swaps or power instability.
V mount battery plate: Secures the GH5 V mount battery to the rig and distributes power to camera and accessories
A V-mount battery plate serves as a connection interface between a professional V-mount battery and your camera rig. It allows you to securely attach the battery to your cage or rig while routing power to both the camera and any connected accessories. Many plates also include multiple output options, such as D-Tap, USB-C, and DC ports, for powering monitors, wireless transmitters, or lighting.
These plates are commonly used on mirrorless camera cages, cinema rigs, shoulder mounts, gimbals, and LED light setups. The battery locks into place with a reliable “V” mechanism, and plates typically attach via 1/4″-20 screws, NATO clamps, or 15mm rod systems for versatility and stability.
When used with the Panasonic GH5, a V-mount battery plate enables longer shooting sessions by securely mounting a high-capacity battery, providing reliable power to both the camera and essential accessories during extended video production.
How to set it up?
Follow these steps to power the GH5.
Step 1. Insert the dummy battery: Place the DMW-BLF19 dummy battery into the GH5 battery compartment.
Step 2. Connect the power cable: Plug the dummy battery cable into the D-Tap or DC output of the V mount battery.
Step 3. Mount the battery: Attach the V mount battery to a V-mount plate, a camera cage, a tripod, or a rig system.
Step 4. Power on and record: Once connected, the GH5 will run continuously as long as the V-mount battery has power.
