1. A method of manufacturing a battery module, the battery module comprising:
a plurality of elongate cells, each cell of the plurality of elongate cells comprising a first cell terminal and a second cell terminal, the first cell terminal and the second cell terminal being located on opposing ends of that cell, the first cell terminal comprising a cell fill plug; and
a busbar comprising a plurality of through holes;
the method of manufacturing the battery module comprising:
aligning the plurality of through holes comprised by the busbar with a plurality of cell terminals of the plurality of elongate cells such that each through hole of the plurality of through holes is aligned with a respective cell terminal of the plurality of cell terminals, wherein the plurality of cell terminals comprises one or more first cell terminals; and
after aligning, electrically connecting the busbar to the plurality of cell terminals of the plurality of elongate cells, wherein electrically connecting comprises welding the busbar to the one or more first cell terminals, which comprise a respective one or more cell fill plugs, in a manner that avoids welding onto the one or more cell fill plugs and/or one or more cell fill plug welds associated with the one or more cell fill plugs.
