Abstract: A method of discharging a battery assembly used to power at least part of an object includes detecting when power to the object is turned off, detecting, with aid of a timer, an amount of time elapsed since the power to the object is turned off, and initiating a controlled self-discharge of the battery assembly when the amount of time exceeds a threshold length of time. The controlled self-discharge of the battery assembly is performed by a self-discharging circuit electrically coupled to the battery assembly.

Abstract: A method for controlling flight includes displaying, in a real-time manner, a picture photographed and sent by a photographing device carried by an aerial vehicle; determining a no-clicking area in the picture based on a position of an obstacle or a no-fly zone; receiving a click operation of a user on the picture; and controlling a flight of the aerial vehicle based on the click operation. Controlling the flight of the aerial vehicle based on the click operation includes invalidating the click operation in response to determining a click location of the click operation being in the no-clicking area; and controlling the flight of the aerial vehicle based on a position of the click location in response to determining the click location being not in the no-clicking area.

Abstract: An aircraft control system and control method are disclosed. The system comprises a remote control apparatus with a first control rod and a flight controller associated with an aircraft. The first control rod is configured to move in a first movement direction to control a motion of the aircraft in a first motion direction when an external force is applied on the first control rod and after a withdrawal of the external force, the first control rod returns to a preset position. The remote control apparatus operates to generate one or more control signals corresponding to the withdrawal of the external force. The flight controller controls the aircraft to maintain a flight state based on said control signals and one or more state signals, which are generated based on a measurement of the flight state by a flight controller associated with the aircraft state measurement sensors carried by the aircraft.
