An electromechanical connector for use between a power source such as a battery and a device requiring the power such as an automotive electrical system. In some embodiments, the connector includes a radius electrical contact constituting a primary electrical current path, and a band clamp with a slotted band constituting a secondary current path, and a worm drive adjustment assembly for symmetrically tighten the connector to the battery post. A kit is described having an electrical-contact conductor with a concave surface conforming to a battery post, and a band clamp to symmetrically compress the conductor against the post. Some embodiments provide a conductor that conforms to an outer portion of the post, and includes a band clamp mechanism with a band fixed at a non-moving end to the conductor, and at an opposite slotted end interfacing to a worm screw held against the conductor.
