The invention discloses an electric vehicle with anti-theft batteries and belongs to the field of transportation means. The electric vehicle comprises a frame provided with a battery containing groove. The bottom of the battery containing groove is provided with a battery gravity sensing alarming device which comprises a bottom plate and a supporting plate located on the upper portion of the bottom plate. A plurality of elastic connecting pieces are connected between the supporting plate and the bottom plate. A gravity sensor is arranged between the supporting plate and the bottom plate and connected with a controller which is connected with the alarming device. The elastic connecting pieces are lower than the gravity sensor in a compressed state. When a battery box is normally inserted in the containing groove, the gravity sensor monitors the weight of the battery box in real time and feeds the weight back to the controller. When the battery box is moved or one single battery in the battery box is stolen, and the controller starts the alarming device to give an alarm when the weight sensor cannot sense gravity or when the gravity is reduced so that the batteries can be prevented from being stolen.
