DJI RS BG21 Grip
The battery grip provides a powerful operating time of up to 12 hours, enough for continuous shooting for most of the day. It supports 18W fast charging with a charge time of just 2.5 hours. It can be used while charging to keep the gimbal powered during use.
A quick-release design makes it convenient for replacement and smaller for easier storage. It can even be charged separately from the gimbal.
