when a hobby enthusiast has recharged the battery for a remote controlled vehicle , such as a scale facsimile automobile , boat , helicopter or airplane , the battery must be connected again to the vehicle drive system , to provide power . this operation is typically performed by connecting each lead of an electronic speed controller to each corresponding lead of the battery , through a removable barrel receptacle lead and a mating barrel plug lead respectively , attached to each corresponding lead . an improved connector lead is described herein that protects components that may be attached to either lead in a connection . the charge dissipates in a resistive member that is physically coupled to a conductive member to form at least in part a first lead . when an improved lead is connected to a mating lead , the connection initially provides a charge dissipation path through the resistive member , but subsequently provides a bypass , current carrying conductive path around the resistive member from one component to another . by making use of an improved connector , electrical components are protected , not only from hot - swap current , but also from electrostatic discharge in general .
