Abstract
A battery pack including an electric coupling assembly. The battery pack includes a top housing, a bottom housing, a cell pad, a plurality of battery cells, a harness, and a circuit board. The harness includes a frame and electric coupler assembly having a plurality of internal and external electric couplings. The internal and external electric couplings include cell couplings and circuit board couplings. The internal and external couplings are held in place during manufacturing by links which are cut after the electric coupler assembly is molded into the frame.
