SmallRig V Mount Battery X99 (99Wh / 6800mAh) with 2.0-inch touchscreen, 100W USB-C and dual D-Tap – 4984
Product description
The essentials
If you regularly power a camera rig, monitor setup or small production lights on the move, a V-mount battery is often the simplest upgrade path. The SmallRig V Mount Battery X99 is built around that idea: one battery format for different ports, plus a management screen and remote app control, so you can see what’s going on without guessing.
On paper, it’s a fairly feature-heavy mid-range V-mount option. You get a 2.0-inch touchscreen for port control and battery status, app control for remote monitoring/port switching and OTA updates, and a USB-C PD connection rated up to 100W. That combination is handy when your “needs” change from shoot to shoot—one day you’re feeding a monitor and lights, the next you’re topping up a laptop or other USB-C device.
It’s not perfect for every scenario, though. A big part of the value depends on whether you’ll actually use the touchscreen/app controls and the specific mix of ports (including D-Tap and both DC barrel sizes). If your kit is very limited and you mainly need one output type, you might find a simpler battery does the job with less faff.
What you’ll notice day to day
The standout daily-use feature here is the 2.0-inch touchscreen with a frosted anti-glare surface. That’s the sort of detail that matters in real lighting: you should be able to check the status more easily when you’re outdoors or under bright set lighting, and you can switch ports on/off from the screen.
There’s also an “anti-misoperation” function mentioned, intended to reduce the chance of accidentally turning off the battery via the touch interface. It’s a small reassurance, because touchscreens can be easy to tap by mistake when you’re wearing gloves or working quickly.
Another practical touch is the small LED light on the back of the battery. It’s there to help you locate the V-mount plate and battery body in darker conditions—useful when you’re swapping batteries on location and the lighting isn’t ideal.
And if you prefer managing things away from the battery, the battery’s dedicated mobile application supports remote control functions, including viewing the status of multiple batteries, controlling port switches, and adjusting battery positioning (e.g., flashing lights and waking the screen). There’s also OTA update support listed, which is worth considering if you like keeping firmware up to date.
Key points for power and charging
The X99 is rated at 99Wh / 6800mAh, with a 100W output capability called out for charging. It’s also designed around fast charging via USB-C PD (PD 3.0 support is specified), with the claim that a 100W (and above) GaN charger can bring the battery to full in around 2 hours.
This is where the battery tends to make sense for mixed rigs: one port for USB-C powered devices, plus D-Tap for accessories that expect V-mount output. The listing also specifies dual D-Tap (2 x D-Tap), and additional charging/outputs including 2 x USB-C, BP and two DC barrel options (5.5 x 2.1mm 8V and 5.5 x 2.5mm 12V), alongside USB-A.
Worth noting: while the battery supports a lot of device types “in the listing’s examples” (camera systems, camcorders, monitors, light accessories, phones/tablets/laptops), the actual compatibility depends on your device’s power requirements and cable/adapter choices. The ports are there, but your kit still needs to match the required voltages and connectors.
Ports and mounting: where it really fits
The battery includes practical mounting support via threaded holes on the V-mount backplate: 1/4"-20 and 3/8"-16. That can help if you’re securing the battery with a ball head or clamp, depending on your rig layout.
If you’re running a workflow where you regularly change what powers what—say, switching from powering a monitor to topping up a USB-C device—port-level switching becomes more than a “nice to have”. The touchscreen can turn ports on/off, and the app is listed as supporting remote port switching too.
It’s a palm-sized form factor for the capacity listed, with dimensions provided in the source and a weight of 31oz. That should help if you’re trying to keep your kit manageable for travel or quick gimbal-style setups.

Safety, durability and the limits to keep in mind
This battery leans into “production ready” durability. The listing specifies anti-drop protection and reinforced construction, plus IP54 for splash/rain/dust exposure. On top of that, the BMS protection list is quite broad: short circuit, temperature, voltage, current, over/under charge and over/discharge.
Still, it’s not a magic shield. IP54 is about splash and dust resistance, not submersion proofing. If your work involves heavy rain setups or you’re regularly dealing with prolonged wet conditions, you’ll still want to consider practical weather protection for the whole rig.
Also, the “2 hours full charge” claim depends on using a suitable charger (100W and above GaN charger is mentioned). If you’re plugging into a slower charger, charging time will likely be longer—so it’s worth matching your charging gear to the battery’s intended fast-charge scenario.
Who it’s for (and who might skip it)
It makes sense if you want one battery that can feed a mixed camera-and-accessories kit: monitors, lights, accessories via D-Tap, and USB-C powered devices. The touchscreen and app control also suit people who like monitoring battery status clearly, especially when multiple batteries are in play.
It might not suit you as well if your kit is simple and you only need one output type. In that case, the extra screen, app features and port variety could be more complexity than you need.
You’ll also want to double-check your devices’ power needs and the port types you actually use. The listing provides several DC voltage options and multiple USB formats, but the final fit depends on cables/adapters and whether your devices accept those outputs.
Is it worth it?
Buy the SmallRig V Mount Battery X99 if you’re building a V-mount power setup for camera work and you value flexible outputs (including dual D-Tap and USB-C PD up to 100W) plus on-device control via the 2.0-inch touchscreen. It’s particularly compelling for travel and quick turnarounds thanks to the 99Wh capacity note for carry-on eligibility and the fast-charge approach, as long as you have a 100W+ GaN charger.
Skip it if your rig is power-light and doesn’t really need the touchscreen/app port switching, or if you’d rather keep things simpler with fewer output types. And regardless of your setup, it’s worth checking that your devices match the listed port voltages/connectors—having the ports is only half the story.
