Power is the unglamorous backbone of every production. Nobody talks about batteries in their behind-the-scenes content, but every working filmmaker knows the feeling of watching a battery indicator drop into the red zone with two hours of shooting left and nowhere to plug in. When you're shooting at a remote outdoor location, inside a warehouse with no accessible outlets, or bouncing between rooms at an event venue, portable power isn't optional. It's mission-critical.
We own two SmallRig V-Mount batteries and they have become essential to how we operate on location shoots across Los Angeles.
The Specs That Matter
The SmallRig V-Mount battery is 99Wh and 6800mAh. That 99Wh number is important because it's the maximum capacity allowed on commercial airline flights without special approval. If you travel for production work, this is the biggest battery you can toss in your carry-on without dealing with airline restrictions.
The battery has six output ports, which is where it really becomes a production tool rather than just a big battery:
- 65W USB-C output (PD 3.0): enough power to charge a MacBook Pro while you're using it
- Standard USB-A ports: for charging phones, wireless mic receivers, and smaller accessories
- D-Tap port: industry-standard connector for LED lights and monitors
- V-Mount plate: snap it directly onto any V-Mount compatible light or device
The PD 3.0 fast charging means the battery itself recharges quickly between shoot days. We can plug it in when we get back to the studio and it's fully charged by the next morning.
How We Actually Use Them
Here's a real example from a recent corporate shoot. We were filming executive interviews at a client's office in El Segundo. The room they gave us had exactly one wall outlet, which was behind a desk we couldn't move. We mounted one SmallRig V-Mount on the back of our LED key light via the V-Mount plate, powering the light for the entire three-hour interview session. The second battery sat on a table next to our workstation, with the USB-C port charging our editing laptop and a USB-A port keeping our Sony A7 IV's spare batteries topped off in a charger.
That's three critical pieces of equipment powered from two compact batteries, with no extension cords, no power strips, and no negotiating with the facilities manager about which outlets we're allowed to use.
On outdoor shoots, the batteries are even more valuable. We shot an engagement session at Griffith Observatory at golden hour, and we used an LED panel for fill light during the last twenty minutes as the sun dropped. The SmallRig V-Mount powered the panel for the entire session with capacity to spare. Without it, we would have been working with natural light only, which sometimes isn't enough to get the shot the couple wants.
Powering Lights and Monitors
The D-Tap output and V-Mount plate are what make this a professional production battery rather than just a USB power bank. Most professional LED panels accept V-Mount batteries directly, so you just snap the battery onto the back of the light and go. No cables, no adapters, completely portable lighting that you can move anywhere on set without being tethered to a wall.
We also use the D-Tap output to power our field monitor during longer recording sessions. The Sony A7 IV's internal battery drains faster when you're running an external monitor, so having the monitor powered independently from a V-Mount battery keeps the camera's battery focused on recording.
Why We Bought Two
After using one SmallRig V-Mount battery for a few months, we bought the second without hesitation. Having two means we always have a fully charged backup, and on bigger shoot days we can power multiple devices simultaneously without making compromises. One battery powers the lights while the other handles cameras, monitors, and charging. For a full-day wedding shoot with ceremony, portraits, and reception coverage, two batteries give us complete power independence for the entire day.
We paid $99.99 for our first unit and $199.99 for the second, which was a higher-capacity version with additional features. Both have been completely reliable, and the price-to-value ratio is outstanding compared to bigger brand V-Mount batteries that can run $300 to $500 for similar capacity.
What We Like
- 99Wh capacity (airline safe): maximum allowed battery size for commercial flights without special approval
- 65W USB-C PD 3.0: charges laptops, not just phones and small devices
- 6 output ports: power multiple devices simultaneously on set
- V-Mount plate: snaps directly onto compatible LED lights and devices
- D-Tap output: industry-standard connector for professional production gear
- Compact and lightweight: easy to mount on lights or carry in a bag
- LED power indicator: shows remaining capacity at a glance
- PD 3.0 fast charging: recharges fully overnight
What to Keep in Mind
The 99Wh capacity is generous, but it's not unlimited. A power-hungry LED panel at full brightness will drain it in a few hours. For our typical use, running an LED key light at 60-70% with occasional adjustments, we get a comfortable full session out of one battery. Plan your power budget based on your specific lights and shooting schedule.
V-Mount is the professional standard, but if your lights and gear use different battery systems, you'll need the D-Tap or USB outputs instead of the V-Mount plate. Make sure your existing equipment is compatible before building a V-Mount power system.
The batteries are solid and well-built, but they do add weight to your kit. Each one weighs about 1.5 pounds. With two batteries plus your other gear, the weight adds up. That said, the alternative is running power cables across a location or not having power at all, so the tradeoff is more than worth it.

The SmallRig V-Mount battery is one of those unglamorous pieces of gear that makes everything else in your kit work better. It gives you portable, reliable power for LED lights, monitors, cameras, laptops, and phones without being tethered to a wall outlet. The 99Wh capacity is airline safe, the 65W USB-C output can charge a laptop in the field, and the six ports mean you can power an entire production setup from a single battery.
We bought two because one wasn't enough for our shoot schedule, and we'd buy a third if we needed to. For any production team doing location work in Los Angeles or anywhere without guaranteed wall power, V-Mount batteries are not a luxury. They're essential, and SmallRig makes the best value option we've found.
