Claim:
1. A battery module, comprising: a housing; a plurality of battery cells disposed in the housing, wherein each battery cell of the plurality of battery cells comprises a first terminal having a first material, and a second terminal; a plurality of bus bar cell interconnects comprising the first material, wherein each bus bar cell interconnect of the plurality of bus bar cell interconnects is configured to electrically couple two adjacent battery cells of the plurality of battery cells via an electrical coupling with the first terminal of one of the adjacent battery cells and the second terminal of the other adjacent battery cell; a plurality of first welds, wherein each first weld of the plurality of first welds is disposed at a corresponding first welding point and directly couples a corresponding bus bar cell interconnect of the plurality of bus bar cell interconnects with a corresponding one of the first terminals comprising the first material; a terminal post connector for outputting a voltage from the plurality of battery cells, the terminal post connector comprising the first material; a printed circuit board (PCB) installed in the battery module proximate to the first and second terminals of the plurality of battery cells; and a shunt disposed on the PCB of the battery module for carrying current from the plurality of battery cells to the terminal post connector, wherein the terminal post connector is welded to the shunt at a first shunt welding point, and wherein the first shunt welding point and each first welding point of the plurality of first welds is accessible for welding from a position above the plurality of battery cells and unencumbered by the installed PCB.
