M?vi Pro is designed from the ground up to minimize downtime on set. Swappable intelligent batteries power the M?vi Pro, camera, and all accessories to keep you shooting all day long with only one type of batteries to charge. M?vi Pro represents a new era of simplification. The two 25.2 volt SL4-Ground batteries provide power for the M?vi. With twice the torque of the first generation M?vi motors and high resolution encoders, M?vi Pro's custom designed direct drive brushless motors are up for any challenge.
