What do V mount batteries do?
V Mount (also called V Lock) batteries are rechargeable lithium batteries that attach to cameras and professional production equipment via a V-shaped locking plate. They deliver sustained power to cameras, monitors, LED lights, wireless video transmitters, and other accessories on set and on location, making them essential for professional broadcast, cinema, and ENG/EFP video production workflows.
What are the best V mount batteries?
The best V mount batteries for professional cinema and broadcast use are those that offer high energy density, reliable output, and compatibility with a wide range of equipment. A 222Wh, 14.8V V Lock battery is an excellent choice for demanding productions, providing extended runtime for cameras like Sony FX9, Sony CineAlta, RED, and Canon cinema cameras, as well as monitors, lights, and accessories. Block Battery, with 30 years of industry expertise, supplies cinema-grade V Lock batteries trusted across the US cinema market.
How many volts to charge a V mount battery?
V Mount batteries typically operate at a nominal voltage of 14.8V. When charging, a compatible V Mount charger is required to safely restore the battery to full capacity. Always use a charger specifically designed for your battery's voltage rating to ensure safe, efficient charging and to protect battery longevity.
What does 222Wh mean for a V Lock battery?
222Wh (Watt-hours) indicates the total energy capacity of the battery. A 222Wh V Lock battery can power equipment drawing 100 watts for approximately 2.2 hours, or a 50-watt device for over 4 hours. Higher Wh ratings mean longer runtimes, making 222Wh batteries ideal for extended shoots without frequent swapping.
Are 222Wh V Mount batteries allowed on airplanes?
No. FAA regulations limit carry-on lithium batteries to 100Wh without airline approval and up to 160Wh with approval. A 222Wh V Lock battery exceeds the 160Wh threshold and is generally not permitted in carry-on or checked luggage without special cargo arrangements. Always check with your airline before traveling with high-capacity batteries.
How long does a 14.8V 15000mAh V Lock battery last?
A 14.8V 15000mAh (approximately 222Wh) V Lock battery can power a camera drawing 50 watts for roughly 4.4 hours, or a 100-watt rig for about 2.2 hours. Actual runtime varies depending on connected equipment, power draw settings, and environmental conditions, but it is well-suited for full-day shoots with moderate power rigs.
Can V Lock batteries power lights and accessories in addition to cameras?
Yes. V Lock batteries with sufficient capacity, like 222Wh models, can power LED panels, on-camera lights, monitors, wireless follow focus systems, and other production accessories in addition to cameras. Battery output voltage and amperage must match the accessory requirements, and many V Lock batteries offer D-Tap or USB outputs for powering secondary devices.
What is the difference between V Mount and Gold Mount batteries?
V Mount batteries use a V-shaped sliding lock mechanism and are widely adopted in Sony and Asian-market cameras. Gold Mount batteries use a three-stud gold contact system and are more common with ARRI and US broadcast equipment. Both serve the same purpose — delivering on-board power to professional cameras and accessories — but require different mounting plates and are not interchangeable without an adapter.
