DJI Ronin BG21 Grip for RS 3 Gimbal

SKU CH-FXSP-Z2VY6

A 3000 mAh grip powers the RS 3 gimbal for up to 12 hours and recharges in 2.5 hours at 18 W

  • Extended shooting sessions with 12-hour battery life
  • 3000 mAh capacity powers RS 3 through full day
  • 18 W fast charging restores power in 2.5 hours
  • Use while charging for uninterrupted operation
  • Cartridge design enables quick swaps and compact storage

Extended Power Grip

The DJI Ronin BG21 Grip attaches to the DJI RS 3 Gimbal and adds a 3000 mAh cartridge battery, giving operators a single-handed grip with integrated power for longer shooting days. It is built for solo camera operators and small crews who need the gimbal to run without swapping batteries mid-session.

12-Hour Runtime and Fast Recharge

The grip delivers up to 12 hours of continuous operation on a full charge and accepts 18 W fast charging via PD protocol, reaching full capacity in 2.5 hours. It supports pass-through charging so the gimbal stays powered while the grip replenishes, though total runtime will drop when driving heavier camera payloads or running accessories from the gimbal’s ports.

Cartridge Design for Quick Swaps

The battery slides in and out like a cartridge, allowing rapid replacement without tools and compact storage in a kit bag. It can also be charged independently from the gimbal, freeing the RS 3 for other tasks while the grip tops up. Buyers who need more than 12 hours between mains power will have to carry spare cartridges or an external power bank.

Questions about this item

Will the BG21 Grip's 3000 mAh capacity still deliver 12 hours on an RS 3 that has seen heavy daily use?

The grip is rated for up to 12 hours of operation on the RS 3; actual runtime depends on payload and shooting mode rather than the gimbal's age.

How can I confirm the 18 W fast charging is active when I plug in the BG21 Grip?

The grip charges fully in 2.5 hours when the PD protocol negotiates 18 W; a slower charge indicates the power source does not support the required voltage range.

Does the BG21 Grip package include a charger or cable, or must I buy a PD-capable adapter separately?

The grip uses a cartridge design for easy swapping and separate charging; a PD-compatible charger and cable are not included and must be purchased separately.
