DJI just announced that all new ronin m will come with a half sized battery x 2 in an attempt to reduce the weight of the handheld gimbal.

Personally I think that is a good move, the current battery last forever when the gimbal is balanced properly. So by reducing the weight, it definitely will enhanced the user experience.
