SmallRig Power Supply Base Plate for DJI RS 2 / RS 3 Pro / RS 4 Pro

In this review the SmallRig Power Supply Base Plate 3252 is evaluated for gimbal operators who need longer run time and more mounting flexibility. The bottom line: this base plate is for photographers and videographers using DJI RS 2, RS 3 Pro or RS 4 Pro who want a reliable external power solution that also adds stable attachment options for car, handheld ring and jib setups. It delivers straightforward power routing with a quick-release fit and multiple mounting points, making it a practical add-on rather than a flashy upgrade.

Key Features

• External power support: Lets the stabilizer run from a D-tap battery to extend shooting time for long sessions or remote shoots.
• Quick-release cartridge: Attaches the stabilizer rapidly and securely to the base plate for faster rig changes and added stability.
• Dual OB302 ports: One OB302 port powers the gimbal while the other can output up to 60W to charge a compatible SmallRig battery plate.
• Multiple mounting points: Two 1/4-20 and one 3/8-16 threaded holes provide secure attachment options for tripods, car suction mounts and quick release plates.
• Accessory compatibility: Works with SmallRig Sling Handgrip 3028 and Dual Handgrip 3027 for handheld configurations without rework.
• Included kit: Ships with the Power Supply Base Plate, OB302 to D-tap adapter cable, a side plate and an Allen wrench so you can install it immediately.

Who It's For

The base plate is aimed at hybrid shooters and pros who use the DJI RS 2, RS 3 Pro or RS 4 Pro and need to run longer takes or use the stabilizer on vehicles and jibs. It is particularly useful on location shoots where AC power is unavailable and when swapping between handheld and car-mounted rigs is frequent.

Those using lighter run-and-gun setups that seldom exceed native gimbal battery life, or users who do not need extra mounting options, may find the extra weight and complexity unnecessary. If you require a built-in battery plate instead of an external D-tap feed, consider other battery-specific accessories.

Pros & Cons

Pros

• Extends gimbal runtime using standard D-tap batteries for longer shoots.
• Quick-release cartridge makes mounting and dismounting the stabilizer fast and repeatable.
• Multiple threaded holes increase flexibility for car, tripod and quick release setups.
• One OB302 port can deliver up to 60W to charge a compatible SmallRig battery plate while powering the gimbal.

Cons

• The mount options receive mixed feedback, so some users may need to verify fit with their existing car mounts or quick release systems.
• It adds extra bulk compared with using just the gimbal and its internal battery.

Specifications

Our Verdict

The SmallRig Power Supply Base Plate 3252 is a practical, well thought out accessory for RS 2, RS 3 Pro and RS 4 Pro users who need extended runtime and added mounting flexibility. It offers sensible power routing with dual OB302 ports and a solid quick-release mechanism, making it good value for shooters who frequently work on vehicles, jibs or long takes and want reliable power and mounting options.

Frequently Asked Questions

Can this plate power the gimbal from a D-tap battery?
Yes. The included adapter cable allows a D-tap battery to power the gimbal via one OB302 port.

Can it charge other SmallRig plates while powering the gimbal?
Yes. The second OB302 port can output up to 60W to charge a compatible SmallRig battery plate such as model 3251.

Will it fit existing car mounts and quick release plates?
It includes two 1/4-20 and one 3/8-16 threaded holes for common mounts, but some users reported mixed results so check thread type and clearance before relying on a specific car mount.
