SmallRig V Mount Battery Plate V-Lock 2991 - Adjustable Rod Mount

In this review of the SmallRig V Mount Battery Plate 2991, the bottom line is simple: this is a practical mounting solution for shooters who need to add V-mount battery capacity to a 15mm rod rig without integrated power distribution. Designed for camera operators who want a secure V-lock platform and flexible placement, it shines for its adjustable arm and multiple mounting points. The plate does not include power outputs or V-Lock electronics, so it is strictly a mechanical mounting accessory rather than a battery plate with on-board power management.

Key Features

• V-Lock compatibility: Uses a standard V mount to accept most V-mount batteries so you can extend runtime with batteries you already own.
• Adjustable extension arm: The articulated arm lets you position the battery along a 15mm LWS rod system to balance and clear accessories on your rig.
• Dual 15mm rod clamp: Included dual 15mm rod clamps secure the plate to a rod setup and prevent unwanted rotation during use.
• Multiple mounting points: A variety of 1/4"-20, M3 and M4 holes plus a locating hole for ARRI accessories make it easy to attach clamps, arms, or other gear.
• Durable aluminum construction: Built from aluminum with included screws and Allen wrenches for a customizable, tool-upfittable mount.
• Battery retention stoppers: Two stoppers help prevent a mounted battery from twisting once locked into the V-lock.

Who It's For

The SmallRig V Mount Battery Plate 2991 is aimed at independent filmmakers, ENG shooters, and DSLR/mirrorless operators who already use a 15mm rod system and want to add V-mount battery capacity without reworking their camera body. It works well for rigs that need the battery positioned off-camera for balance or to clear accessories.

It is not for users who need integrated power outputs, USB or PD charging, or those using PAGlink V-mount batteries or the Patona Premium BP-190WS, since the plate is a passive mount only. Buyers seeking on-board power distribution or a male V-Lock part included should look elsewhere.

Pros & Cons

Pros

• Solid V-lock compatibility that accepts most V-mount batteries for extended runtime.
• Adjustable arm and dual 15mm clamps provide flexible placement and good rig balance options.
• Multiple threaded holes and an ARRI locating hole for high customization with other accessories.
• Includes screws and Allen wrenches so it is ready to install on arrival.

Cons

• Mixed feedback on build robustness from some users suggests it may feel less heavy duty under very heavy loads.
• Contains no electronics or power outputs; it is strictly a mounting solution.

Our Verdict

Users needing built-in power outputs or the highest heavy-load rigidity should consider a powered plate or heavier-duty mounting option.
