Disclosed herein is a vehicle including an electrical system comprising a direct current drive motor, first and second battery sets, a charger adapted to be plugged into an alternating current source, and a selector switch movable between first and second positions and operable, when in the first position, to connect the first and second battery sets in parallel relation to the motor operable, when in the second position, to connect the first and second battery sets in series relation to the motor and to the charger. In addition, the electrical system includes an "off-on" switch interposed between the motor and the selector switch and operable to selectively open and close the connection of the motor to the selector switch whereby, when the "off-on" switch is opened, and the selector switch is in the second position, the charger can be plugged into an alternating current source to charge the battery sets and whereby, when the selector switch is in the first position, the charger is electrically disconnected from the battery sets.
