The vehicle's battery is designed to provide 35 amps for an hour when fully charged or half that for two hours, giving the C5 a claimed range of 20 miles (32 km).[1] A display in the cockpit uses green, amber, and red LEDs to display the state of the battery charge. The segments are extinguished one after the other to indicate how much driving time is left. The last light indicates that only ten minutes of power are left, after which the motor is switched off and the driver is left to rely on the pedals.
