Abstract

A battery pack may include a plurality of cells arranged substantially adjacent to each other such that longitudinal centerlines of each of the cells are aligned substantially in parallel with each other in a first direction, a physical cell connection assembly that includes a cell-retaining portion disposed to contact each of the cells to hold the cells in a housing, an electrical cell connection assembly that includes a plurality of cell connectors disposed to contact at least selected ones of the cells in groups to facilitate electrical connection of the cells associated with each of the groups, a contact portion of each of the cell connectors being disposed to electrically connect electrodes of at least two of the cells, and a printed circuit board (PCB) configured to monitor electrical parameters associated with the cells based on electrical communication between the PCB and the electrical cell connection assembly.
