A V mount Li ion battery is a rechargeable power source widely used in professional film and TV production gear. It features a standardized V-lock interface (with a metal card slot), offering high capacity, strong power output, and a quick-release design. Its primary function is to deliver reliable power to professional cameras (like ARRI and RED), high-powered LED lighting, and other production equipment. These batteries support hot-swapping, making them ideal for extended shoots and demanding on-set environments.
In this post, we will focus on the following topics:
- How to choose a suitable V-lock Li-ion battery
- What options are worth investing in
- How to store and care for them
How to choose the best V-mount lithium-ion battery?
To choose a suitable V-mount Li-ion battery, you need to consider the following factors.
Estimate the power requirements and runtime to decide the capacity of V mount lithium-ion battery
Identify the power consumption of your camera, lighting, and other gear—typically measured in watts (W). Next, compare that to the battery’s energy capacity, which is given in watt-hours (Wh). To estimate how long the battery will last, divide its watt-hour rating by the device's power usage.
✨General Formula:
Battery life (hours) = Battery capacity (Wh) ÷ Power consumption (W)
Example: A 98Wh battery used with a 25W light would run for approximately 3.9 hours.
Check output options and ensure compatibility with your devices
V-Mount batteries vary in the types of output ports they offer, which can significantly impact compatibility with more complex setups. While traditional models include a 14.4V D-Tap, many newer options feature additional ports such as USB-A, USB-C PD, 12V regulated barrel outputs, and 8V outputs for powering DSLRs or mirrorless cameras.
If you're running several devices—like cameras, monitors, wireless transmitters, and follow-focus systems—from a single battery, it’s important to choose one that can handle multiple outputs simultaneously without risk of overload.
Some models also come with built-in OLED displays, which are helpful for monitoring power usage across several devices. Be sure to verify whether your equipment requires regulated outputs, especially when dealing with sensitive electronics.
Consider your travel and shooting environments, as they can also influence capacity needs
If you fly frequently for shoots, battery capacity is crucial due to airline restrictions. Batteries under 100Wh are unrestricted in carry-ons, 100–160Wh are limited to two spares per person, and anything over 160Wh is banned on passenger flights. That’s why many professionals travel with two 99Wh batteries and a dual charger or hot-swap plate to stay compliant without sacrificing power.
Also, for cold or harsh environments, choose batteries that are sealed, temperature-resistant, and deliver stable output under pressure.
Take form factor & mounting style into account
The size and form factor of V-Mount batteries greatly impact rig comfort and usability. Full-size models work well with large cinema cameras and power-hungry lights, often aiding balance with heavy gear. Mini V-Mounts, on the other hand, are ideal for mirrorless setups, gimbals, or compact rigs—offering up to 150Wh capacity with ports like D-Tap and USB.
Mounting options vary, too, from rear plates for shoulder rigs to side or top mounts. Choose what best suits your gear and shooting style.

How to store and care for V mount Li-ion battery?
Proper storage and care help you get the most out of your V-mount battery. Here are 7 tips to follow.
💡 Store at the Right Charge Level. Charge your batteries to around 50–70% before placing them in long-term storage. Doing so helps preserve their capacity and extends their overall lifespan.
💡 Use a Quality Charger with Status Indicators. Choose a reliable charger that shows battery health and charge levels. This helps prevent over-discharge and supports safe long-term storage.
💡 Control Storage Temperature. The ideal temperature is around 50°F (10°C) or room temperature. Avoid high heat—excessive temperatures accelerate self-discharge and degrade cells. Never leave batteries in direct sunlight or a hot car.
💡 Manage Humidity. Maintain around 50% humidity. Avoid moisture exposure, which can lead to terminal corrosion, short-circuiting, or overheating. Always cover battery terminals during storage.
💡 Check Batteries Periodically. Even in storage, batteries slowly lose charge. Regularly check and recharge stored batteries to keep them within the safe voltage range.
💡 Avoid Deep Sleep State. Batteries left too long with low voltage may enter a sleep state and be difficult to recover. Prevent this by storing at the correct charge and checking periodically.
💡 Follow Safe Charging Practices. Use a charger compatible with your battery type (e.g., V-mount). Charge in a temperature-controlled environment to avoid performance issues.
