A surgical instrument (10) includes a housing, an energizable member (220), a powered deployment assembly (80) and a cable assembly. The energizable member is configured to supply electrosurgical energy to tissue and is movable between a storage position and a deployed position. The powered deployment assembly is configured to selectively move the energizable member between the storage position and the deployed position. The cable assembly has a cable coupled to the housing at a first end and has a plug coupled to the cable at a second, opposite end. The cable houses one or more first wires for selectively providing electrosurgical energy to the energizable member and one or more second wires for selectively providing power to the powered deployment assembly. The plug is configured to house a battery (56) therein for powering the powered deployment assembly via the one or more second wires.
