DJI RS BG21 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 RS 3 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.
