V-mount batteries are external power sources commonly used with professional video cameras, lights, and monitors. They are named after the V-shaped mounting system they feature, which ensures a secure connection to various devices. There are models with different voltage and amperage. In this article, we will focus on V mount battery voltage, talking about the following topics:

What is voltage of V mount battery?
The typical nominal voltage for a V-mount battery is 14.8V, which is derived from four lithium-ion cells connected in series (each rated at 3.7V). However, depending on the manufacturer's specifications, these batteries are often labeled as either 14.4V or 14.8V.
Applications:
- Video cameras
- Field monitors
- LED lights
- Other accessories like external monitors or wireless transmitters
For high-voltage needs, specialized 24V or 26V V-mount batteries are available. These feature 6 or 7 lithium-ion cells connected in series, unlike the standard 4-cell configuration.
- 6-cell (6S): Nominal voltage is 22.2V (6 × 3.7V per cell), often marketed as 24V.
- 7-cell (7S): Nominal voltage is 25.9V (7 × 3.7V), sometimes labeled as 26V.
Applications:
- High-power cinema cameras (e.g., ARRI Alexa Mini LF, RED Komodo).
- Professional lighting systems (LED panels, HMIs).
- Devices that require a stable, high-voltage power supply.
14.4V VS 26V V mount battery: How to decide which voltage to choose?
When deciding V mount battery voltage, it's crucial to take into account various factors related to your equipment's power requirements and how it will be used. Here's a guide to the essential points to help you make an informed choice:
Equipment compatibility
14.4V: These are widely used in DSLR cameras, mirrorless cameras, and smaller video gear. Many portable cameras, lights, and gimbals are compatible with 14.8V batteries. If your equipment is designed to operate at this voltage, a 14.8V battery is the ideal option.
26V: Typically used with larger cinema cameras, high-power lights, and professional video gear that require higher energy output. If you're working with more extensive setups like ARRI, RED, or powerful LED lights, a 26V battery is better suited as it provides more power over extended periods.
Power output
14.4V: These offer lower power, making them suitable for small to medium-sized equipment. While they can power devices for a reasonable duration, they may not be able to handle high-power consumption gear efficiently.
26V: Designed for high-power needs, these batteries provide more amperage, allowing larger systems to operate for longer periods without depleting their charge. They're perfect for situations where multiple devices need to be powered simultaneously or when running high-power equipment like large lights and cameras for longer periods.
Battery runtime
14.4V: These batteries tend to have shorter runtime when used with high-drain devices. However, for smaller cameras and lights, they are generally sufficient.
26V: With higher voltage and capacity, 26V batteries last longer under heavy loads and are more suitable for power-hungry equipment, especially during extended shoots on set.
Size and weight
14.4V: These are typically smaller and lighter, making them perfect for handheld use or compact setups. They won’t add significant weight to your camera rig or require extra effort to handle.
26V: Larger and heavier, these batteries are more suited for stationary or mounted setups where portability is less of a concern. Their bulkiness may be a factor if you're prioritizing portability.
Cost
14.4V: Generally more affordable than 26V batteries, both in terms of upfront cost and maintenance.
26V: With a higher power output and larger capacity, 26V batteries are more expensive. However, they offer greater value in professional settings where consistent high power is required.

Three picks of 14.4V V mount battery recommended at Moman
The Moman V-mount battery offers an excellent balance of quality, affordability, and portability. It is a top choice for V-mount battery models approved for air travel, allowing easy transportation on airplanes without security issues. Here are 3 popular models with a nominal V mount battery voltage of 14.4V.
Moman Power 99
The Moman Power 99 offers a 99-watt-hour capacity, just under the 100-watt-hour limit commonly allowed by airlines. This makes it an excellent choice for filmmakers on the go. It features a simple five-bar indicator to show its charge level.
One of its key features is the inclusion of two D-Tap ports. This allows users to power additional devices, such as lights or monitors, and also charge the battery itself. Additionally, there are two USB ports located beneath a small rubber cover on top, adding to its flexibility.
What sets the Power 99 apart is its 15-amp draw, enabling it to power 200-watt lights at full intensity. However, battery life depends on the device's power usage. For example, a 200-watt light would run for less than 30 minutes, but the battery can last much longer when the lights are not used at full power.
Moman Power 99 Pro
The Moman Power 99 Pro offers the same 99Wh capacity and 15-amp draw as the Power 99 but introduces an OLED screen and a single D-Tap port.
The OLED display is a significant upgrade, providing users with immediate access to key information such as voltage and amp draw. This helps manage equipment more effectively and avoid unexpected power disruptions during shoots.
Charging the Power 99 Pro can be done through either D-Tap or USB-C. Although D-Tap charging is quicker, the addition of USB-C charging provides more options for users without access to a D-Tap charger. This versatility is especially useful for professionals who need fast and convenient charging while on the move. Furthermore, the inclusion of both USB-A and USB-C ports lets users power multiple devices simultaneously.
Moman Power 99 Touch
The Power 99 Touch is a 99Wh V-mount battery, designed to comply with airline regulations that limit battery sizes. This makes it especially convenient for traveling filmmakers and photographers, as it can be carried on flights without any issues.
While both the Power 99 Pro and Power 99 Touch feature display screens, the Power 99 Touch offers information such as the discharge interface, capacity, and remaining operating time.
It includes D-Tap, USB-A, USB-C, and BP ports, similar to the other Moman models. However, it stands out with the addition of an 8V DC port, which allows it to power accessories like field monitors, wireless transmitters, audio recorders, and portable LED lights when AC power is unavailable.
