DJI RS BG70 High-Capacity Battery Grip

The battery lasts forever (it's also charging the RavenEye). I can hold it with both hands, without relying on the flimsy stand extension. The old (standard) grip is now collecting dust.

Perfect one that I need for long hours using DJI RS4 Pro. Thanks

Summary: The DJI RS BG70 High-Capacity Battery Grip is a solid upgrade for filmmakers using power-hungry setups on the Ronin RS 4 Pro. While it adds some bulk, it delivers extended runtime, a more substantial grip, and potential for powering accessories via USB-C. A dead-on-arrival battery was a minor hiccup, but overall, this is a professional-grade addition worth considering.Why I Chose this Product:I purchased the BG70 to supplement the default battery on my DJI Ronin RS 4 Pro, especially since my rig includes nearly 10 lbs. of camera gear, the DJI Focus Pro LiDAR, and lens motors. (see photo)Even during basic balance and focus tests, I noticed the default battery draining quickly—raising concerns about power longevity during full-day shoots, so I clipped on a v-mount battery, massively increasing the weight (see photo). The BG70 offers me the possibility for peace of mind with its higher capacity, reducing the need for frequent battery swaps or external V-Mount solutions.Build Quality and Design:As expected from DJI, the build quality is excellent. The grip features the same rubberized texture as the default handle, ensuring a secure hold. It’s roughly twice the length of the standard grip, which adds some weight and length to the rig but also provides a more comfortable and stable grip during handheld operation.Charging and Power Features:The battery arrived completely discharged—unusual, but not a dealbreaker. After charging, it locked into the Ronin handle securely and functioned as expected. A standout feature is the USB-C port, which is advertised to power additional accessories. I haven’t tested this yet, but it could be a game-changer for powering monitors or transmitters directly from the grip. If I can update this review after further testing, I will do so.Mounting Options:An added bonus is the inclusion of a 3/8" mounting thread alongside the standard 1/4", offering more weight bearing flexibility, even perhaps I can consider mounting my gimbal upside down on a Jib.

I bought it thinking about the long lifespan the product is advertised as. I tested it in my studio, and without doing any gym ball movements, just keeping it on, this grip lasts more than nine to 11 hours—far from the 29 hours the brand claims. I communicated with the salespeople, explaining to them; they were very kind to me, but they never really addressed my concerns.
