SmallRig V-Mount Battery Plate 4505 with L-Shape, Foldable Tool-Free Mounting (V-lock)
Product description
What it is and why you might want it
The SmallRig V-Mount Battery Plate 4505 is a compact V-lock mounting plate designed to integrate a V-mount battery into a camera setup without making the rig feel bulky. It takes an L-shaped, space-saving approach and combines a V-mount plate with a stretchable base plus threaded mounting points, so you can position the battery and add-on accessories as your setup demands.
On paper, it’s aimed at builders of DSLR/mirrorless rigs, stabiliser users, and tripod shooters who want quick battery placement and storage. It also includes an Arca-style mount clamp for compatibility with SmallRig cages that use an Arca QR plate, which is a useful detail if you’re already thinking in that platform.
That “compact and foldable” angle matters in real life: if you shoot travel or you pack your kit often, being able to collapse the form factor is one of those small wins that can save you time and hassle.
Key takeaways
Key takeaways
The core appeal here is convenience. The rod/positioning uses a toggle lock for quick install and adjustment, so you don’t need tools just to move things around.
There’s also a rotatable V-mount plate that can be adjusted by 180°. The idea is straightforward: set it one way for easier storage, and rotate it the other way to give you space to open the camera flip screen. It’s also described as having pivot damping, which should help prevent equipment from dropping.
The bottom of the plate includes 1/4"-20 and 3/8"-16 threaded holes, which is handy if you need to attach a quick release plate or other accessories that use those standard threads.
Where it shines in day-to-day use
If you regularly switch between handheld-style setups and tripod/gimbal mounting, this kind of plate is meant to reduce fiddling. A typical workflow could look like this: mount your camera cage, slide the V-mount plate into place using the quick toggle adjustment, then fine-tune the rod position so the battery sits properly for your rig height.
The stretchable base is meant to help with camera size differences. The spec provided is a maximum stretchable distance of 36.5 mm, which suggests it’s trying to be adaptable rather than forcing one fixed fit.
It’s not the sort of item you “set and forget” forever, it’s more for people who adjust their build from job to job, or who don’t want to constantly retool their rig.
What to check before you buy
Before assuming it will be the perfect match, there are a few practical checks worth doing.
First, this plate is described as suitable for mirrorless/DSLR cameras less than 111 mm thick. If your camera plus any added cage components pushes thickness beyond that figure, you may need to look elsewhere.
Second, the Arca clamp is specifically described as supporting SmallRig cages with a QR plate for Arca. If your system uses a different cage/QR approach, don’t assume Arca compatibility automatically—double-check your existing cage and QR plate style.
Third, the rotation feature is designed around battery mounting and screen access, but it won’t replace the need for thoughtful rig planning. You’ll still want to confirm that your battery position won’t interfere with your particular screen hinge or cable routing.
Also, note the stated dimensions (113.5 mm x 30 mm) and weight (199 g). That points to a compact accessory, but if you’re expecting a substantial power solution or an integrated battery solution, this is a mounting plate rather than a full power system.

Buying verdict
Final verdict
It makes sense if you want a foldable, compact V-mount battery plate that focuses on quick adjustment, a stretchable base for different camera sizes, and threaded points for accessories. If your setup involves a cage (especially SmallRig cages with an Arca QR plate), plus you regularly reposition your rig or need flip-screen clearance, this one is likely to feel practical.
You may want to skip it if your camera setup falls outside the stated thickness guidance (less than 111 mm thick), or if your existing mounting ecosystem doesn’t line up with the described Arca QR compatibility. It’s also not the best match if you’re looking for something that replaces the need for a complete battery/power solution—this is about mounting and flexibility, not providing power by itself.
A solid approach is to compare your current cage/QR system and your camera’s thickness with the guidance given here, then decide whether the stretch range and rotation are likely to reduce your day-to-day rig adjustments.
Mini FAQ
Usage tips
Does it need tools to adjust the mounting position? The rod locking/releasing uses a toggle lock, described as fast and without needing tools.
Can the V-mount plate rotate for screen access? Yes, it’s adjustable by 180°, with guidance that one direction supports convenient storage and the other helps with space to open the flip screen.
What threads are available for accessory mounting? The base includes 1/4"-20 and 3/8"-16 threaded holes.
Is it compatible with any camera? It’s described as suitable for many mirrorless/DSLR options on the market, but the guidance includes a thickness limit of under 111 mm.
Is it a battery pack or just a mounting plate? This product is a V-mount battery mounting plate (the listing describes the plate and mounting features), not a standalone battery pack.
