A system includes a cell interconnect board including a printed circuit board (PCB) disposed proximate a power assembly having a plurality of pouch battery cells, including at least a first battery cell and a second battery cell in a stacked orientation relative to each other. The cell interconnect board includes an interconnect spanning a slot in the cell interconnect board and configured to receive a first tab electrode extending from the first battery cell and a second tab electrode extending from the second battery cell, such that the first and second tab electrodes are in contact with each other. The system also includes a sensor configured to measure a parameter associated with the power assembly.
