Abstract
A stand-alone motor unit includes a base having a first side and a second side adjacent the first side, an electric motor arranged in the base and including an output shaft, a power take-off shaft receiving torque from the motor and protruding from the second side of the base, a battery pack, and a battery module removably coupled to the base. The battery module includes a side wall and a battery receptacle for receiving the battery pack for providing power to the motor when the battery module is coupled to the base. The battery module is configured to be coupled to the base in a first position, in which the side wall of the battery module is parallel with the second side of the base, and in a second position, in which the side wall is perpendicular to the second side of the base.
