A charging system for an Implantable Medical Device (IMD) is disclosed. The charging system features an electronics module connected to a charging coil by a cable. The charging system can be configured with a belt or harness that holds the charging coil position to charge the IMD and also providing a user with easy access to the electronics module. Resistance in the cable between electronics module and the charging coil is minimized by using multiple, individually insulated conductors to carry AC current.
