The Ronin BG30 Grip is compatible with the DJI RS 4, RS 4 Pro, RS 3 Pro, and RS 2 gimbals. It's the same grip that is included with these gimbals. The BG30 features an integrated battery that powers the gimbal for up to 12 hours. Via a USB Type-C charging port, the integrated battery can be recharged from 0 to 80% in approximately one hour. When using a fast charger, it can be fully charged in 1.5 hours. The BG30 supports fast charging protocols 24W PD and QC2.0, and the battery can be charged even when removed from the gimbal.
