SmallRig Mini V Mount Battery Plate (2989) with crab-shaped clamp for camera power
Product description
If you’re building a tidy V-mount power setup for a camera rig, the SmallRig Mini V Mount Battery Plate (2989) is the kind of accessory that quietly solves a practical problem: getting a V-mount battery securely on your support system. It’s not a power system by itself, more of a mounting plate that lets your battery’s own outputs do the work.
On paper, this is aimed at people who already have a V-mount battery with power ports and want a compact, road-friendly way to attach it to a tripod, light stand or a gimbal ring. It’s also the sort of add-on that tends to make sense when you’re trying to reduce faff between shoots — quick, repeatable mounting beats improvised straps, especially when you’re moving between locations.
The essentials
The 2989 is a mini V-lock battery mounting plate made for V-mount batteries. It includes a crab-shaped clamp designed to help you attach the battery plate to a support with a rod diameter between 15mm and 30mm. The plate itself is built from aluminium and is noted as weighing just 2.2 oz, which matters if your kit is already heavy on “small but essential” parts.
One point to be clear about: the plate has no electronics and doesn’t provide power outputs on its own. It’s purely a mechanical mounting solution, so the battery you choose needs to include the power port(s) you’ll feed into your camera, monitor or accessories.
What you’ll notice in use
In practice, the crab-shaped clamp makes it feel less fiddly than solutions that rely on bulky brackets. If you’re working with a tripod and want the battery positioned neatly while still keeping your cable runs sensible, this plate’s clamp approach is designed for that kind of setup.
A small real-world example: imagine you’re doing an on-location interview. You slot the plate onto a stand/tripod area using the clamp, attach your V-mount battery via the V-lock mount, then route power from the battery into your camera accessories. When you change angle or move to the next location, you’re not rebuilding the whole power mounting every time.
That said, it’s not the kind of product you can “set and forget” without paying attention to placement. The instructions note you should avoid installing the crab-shaped clamp in the centre of the plate to achieve maximum compatibility of the clamp, so do check the installation form before tightening things up.
Key specifications
- Type: V-lock battery mount / battery plate for V-mount batteries
- Rod diameter supported by clamp: 15mm to 30mm
- Weight: 2.2 oz
- Plate mounting points: two 1/4-20 countersinks, two 1/4-20 thread holes, and four M4 thread holes
- Materials: aluminium
Where it shines (and where it might not)
Where this earns its keep is in flexibility of mounting. The plate doesn’t just mount a battery, it also provides multiple thread points (1/4-20 and M4) that can be used to attach accessories such as a dual rod clamp, a magic arm or other hardware. That makes it useful if your rig needs “one more attachment” for cables, a monitor, or small accessories while keeping the battery placement stable.
It’s also a good fit if you want a lighter, more portable mini form factor for travel and quick setup.
It may not suit you if you were hoping for an all-in-one power solution. Because there are no electronics and no power ports on the plate, you’ll still need the V-mount battery that provides the power outputs for your gear.
Also, there are explicit compatibility limits to consider. It is not compatible with PAGlink series V-mount batteries and it is not compatible with Patona Premium Battery for BP-190WS. And the listing also notes that no V-Lock part (male) is provided with the plate, so don’t assume you’re getting a complete battery mount kit in the box.
Compatibility and requirements
This mount is built around a V-lock mount and a quick-release lever, and it’s described as fitting most V-mount batteries. However, the “most” doesn’t mean everything, so it’s worth double-checking your battery brand/series before committing.
The clamp is the other half of the compatibility story: if your stand/tripod/gimbal ring uses a rod diameter outside 15mm to 30mm, you may struggle to get a solid fit.
Finally, because it’s meant to mount a battery that has its own power outputs, your chosen battery should be able to supply your camera rig directly (via its ports) without relying on the plate.
Final verdict
It makes sense if you already own a compatible V-mount battery and you want a compact, aluminium mounting plate with a crab-shaped clamp for attaching the setup to rods on a tripod, light stand, or handheld ring for gimbals. If you like the idea of adding accessories through the 1/4-20 and M4 mounting points, it’s a practical step towards a cleaner rig.
You may want to skip it if you’re expecting the plate to provide power ports or any electronics, or if your battery is from the listed incompatible lines. It’s also not the best match if your rod diameter falls outside 15mm to 30mm.
In short: this is a sensible mounting solution for V-mount users who care about build order and cable routing. Just don’t forget the “no electronics, no ports” reality and the specific battery compatibility notes.
Mini FAQ
