Winter Warning
The DJI Ronin cannot be used outdoors in winter conditions below -10°C.
Page 13 of the DJI Ronin RS 2 User manual states that using the grip 
(therefore the gimbal) below -10°C may cause permanent damage!
Also on that page, it encourages charging the grip in a place that is above 
5°C, but ideally at room temperature 22 to 28°C.
