Well known functions or constructions may not be described in detail for brevity and/or clarity. 
     DISCUSSION OF THE PRIOR ART 
     The present invention provides for the rapid removal and replacement of a battery power pack minimizing the break in supply of electrical power to the load. The process includes the removal of the electrically discharged battery pack, the insertion and retention of a charged battery pack, the retention being facilitated by magnetic means, said means further incorporating electrical conduction, and the mechanical provision of degrees of freedom of motion or the battery pack relieving mechanical connection stresses and assuring continuous and assured electrical connection during operation of an electrical load. 
     The present invention provides a battery pack with a flexible but fixed electrical and mechanical connection means allowing limited mechanical motion of the battery pack without excessive mechanical tension on the electrical connection preventing loss of electrical contact. It also provides for the retention of a control device and the connection to a load. In the case of a hand held or body mounted load such as a power tool the present invention may be mounted on a body part such as the arm, hand or leg. In this manner the battery moves with the body without undue stress on the magnetic mechanical connection maintaining uninterrupted electrical connection. 
     The present invention provides for the electrical connection and mechanical support of a battery through the electrically conductive plating on the attractive magnets and for a conductive surface between the coupling magnets insuring proper alignment and electrical conduction. Further, the present invention embodies the forming of opposing electrical polarities in the magnetic north and south magnetic fields utilizing the natural attraction of the magnetic fields to facilitate the properly oriented electrical connection. The electrical connection may be of any known type to include Direct Current, Alternating Current, and signal or combined power and signal as preferred for the application. The magnets on either side of the battery pack connection need to be of proper polarity to attract and may all be of the same polarity or be reversed or alternated in respect to each other so as to attract or repel as per the desired operation with or without the requirement for insulating material between the conductors as per the required application. Electrical polarities being so oriented and their connectivity so controlled are a preferred embodiment of the present invention. 
     In terms of hand held battery operated tools the present invention provides for a battery powered portable system of operating the tool where the battery and associated controls can be worn on the users body or clothing, the battery connecting via conductive magnetic means that further mitigate excessive mechanical motion reducing or eliminating mechanical stress on the electrical connection. The present invention further provides for the electrical connection and mechanical support of a battery through the electrically conductive plating on the attractive magnets and by the electrical conductivity of the magnets themselves providing a captured conductive surface between the coupling magnets insuring proper alignment and electrical conduction. The present invention further provides mechanical flexibility of the magnetic electrical connectors assuring electrical contact by mitigating minor alignment or mechanical contact issues. 
     The present invention facilitates complete reversibility of the magnetically polarized electrical connection with assuring correct electrical connection at all times in any orientation as it is reversible. The present invention assures contact of the magnetic conductors by separating them with a structural but flexible connective material assuring complete electrical contact at all times. 
     Mounting the battery on the electrical load adds weight and complexity to the load, such as a power tool. This weight must be supported and moved with the load during use. The present invention provides for the flexible magnetic connection of the battery in a multiplicity of configurations, including attachment to the arm, leg or body further facilitating electrical connection to the tool via a short electrical connector and the convenience of electrical controls being available at the battery at all times. In this manner the present invention provides for no battery weight on the load, such as an electric tool. 
     The present invention integrates the magnetic and conductive functions and is further integrated with the battery pack forming a single unit providing a connectable battery function that is mechanically supported by the magnetic action of the electrically connecting element. Mechanical flexibility is provided relieving stress on the conductive connective magnets facilitating incidental motion of the battery relative to the connector.

     DETAILED DESCRIPTION OF THE INVENTION 
     Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developer&#39;s specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure. 
     The present invention relates to the mechanical connection of electrical power and a load through conductive elements by action of integrated magnetic elements and associated controls. In particular to the conduction of electrical current via conductors brought into mechanical contact by integrated magnetic elements to power a load. 
       FIG. 1  illustrates the principal components of the present invention. It is comprised of the individual components including a Battery Pack  1 , Battery Pack Connector Magnets  2 , Band  3 , Integrated Controller  4 , Power Output Connectors  5 , Cable Connectors  6 , Band Magnetic Connectors  7 , and Cables  8 . The Battery Pack  1  is comprised of batteries, not shown, with integrated electronics, controls, condition indicators and power regulation. 
     The Battery Pack  1  supplies electrical power through Battery Pack Connector Magnets  2  to Band Magnetic Connectors  7 . The electrical power supplied is AC or DC at a voltage and a current as required, and in the case of AC at a frequency as controlled by the Battery Pack  1  integrated electronics and power regulation. 
     Battery Pack Connector Magnets  2  and Band Magnetic Connectors  7  are electrically conductive magnets. They are arranged in a line and their electrical and magnetic polarities are selected to provide a correct electrical connection even if the mechanical connections are reversed. This means that the Battery  1  may be removed, turned one hundred and eighty degrees around (reversed) and reconnected without changing the electrical connection. It is a preferred embodiment of the present invention that the outermost magnets, located at the first and third position of the line of magnets, be of the same magnetic polarity on their exposed side away from the Battery Pack  1 , and that the center magnet have an opposite magnetic polarity on the exposed side away from the Battery Pack  1 . It is a preferred embodiment that the magnets of the Battery Pack  1  are arranged to be of the opposing magnetic polarity to facilitate the magnetic connector to Band Magnetic Connectors  7 . 
     In this manner the electrical polarities will always orient properly regardless if the Battery Pack  1  is attached in either direction. The present invention integrates the magnetic and conductive functions and is further integrated with the battery pack forming a single unit providing a connectable battery function that is mechanically supported by the magnetic action of the electrically connecting element. 
     The Band  3  facilitates the wearing of the present invention on an object such as an arm or leg, and houses Integrated Controller  4  while providing for the electrical output Power Output Connectors  5 , along with the magnetic mechanical and electrical connection of Battery  1  by Band Magnetic Connectors  7 .

When conductive magnets are brought together they attract each other and mechanically contact forming an electrically conductive connection. In this manner the assemblies will connect in any direction and can be aligned such that only one, two or all three magnetic actions of each assembly contact the magnetic actions of the other assembly. This may or may not be desirable depending on the application. Many other combinations and connection orientations are possible and are included as preferred embodiments of the present invention.
