1. A method for connecting a flexible printed circuit (FPC) to a battery module and a cell supervision circuit board (CSCB), the method comprising:
providing a coil of a continuous, strip-shaped FPC;
unwinding a first section of the FPC from the coil, positioning the first section of the FPC over a first contact portion of the battery module, and welding a conductive structure of the FPC in the first section to the first contact portion of the battery module;
unwinding a second section of the FPC from the coil, positioning the second section of the FPC over a contact pad of the CSCB, and welding the conductive structure of the FPC in the second section to the contact pad of the CSCB; and
separating the first section and second section of the FPC from the coil of the FPC.
