The battery assemblies are at a distance away from the central 71. controller for reducing electromagnetic interference to the central controller. In some embodiments, the aerial vehicle is an unmanned OC ,-1 aerial vehicle (UAV) having a center unit, a plurality of rotor units circumferentially uniformly distributed about and coupled to the .-0-6 center unit, and one or more battery assemblies. The central controller is in the center unit and the propelling modules are in respective 1-1 rotor units. Each battery assembly is in a rotor unit in proximity with the propelling module thereof. In some embodiments, the central CZ controller also has a battery-power balancing circuit for balancing the power consumption rates of the one or more battery assemblies.  el c Date Recue/Date Received 2019-09-14
