The DJI RS BG70 Battery Grip is a high-capacity grip designed to extend shooting times for your RS stabilizer, like the DJI RS 4 Pro. This grip features an internal lithium-ion battery designed to power your stabilizer for up to 29.5 hours. To charge the grip, you’ll use the USB-C port and a separately available USB-C cable, and for fast charging in just 2.5 hours, you can use a USB-C to USB-C cable. You can also use the USB-C port to charge accessories while the grip is in use.
