Removable power supply for a motorized shutter assembly
A removable power supply is provided for use with a motor of a shutter assembly. The removable power supply may include a base housing a battery, a shaft, and a flexible conductor coupled between the base and the shaft. The end of the shaft opposite of the flexible conductor has an electrical interface that is configured to supply power to the motor. The electrical interface is configured for removable coupling to the motor. The shaft may comprise a plurality of telescoping sections, or may be a unitary member. The telescoping sections may be a series of interlocking hallow tubes. The removable power supply may supply power to the motor, thereby allowing a shutter curtain of the assembly to be raised or lowered. Once the shutter curtain is at the desired position, the removable power supply may be removed from the shutter assembly.
