Abstract

A battery pack may include a plurality of cells, a cell connector assembly, and a common output. The cell connector assembly may be disposed to contact at least selected ones of the plurality of cells to facilitate parallel connection of contacted cells. The common output may be electrically coupled to the cell connector assembly to receive a combined output from the plurality of cells. The cell connector assembly may include a plurality of metallic arms arranged in a hierarchical structure including at least two levels each having at least one arm, such that the cell connector assembly defines a plurality of current paths from each of the contacted cells to the combined output. The plurality of current paths are substantially equal to each other in length.
