A system for balancing battery cell charge in a battery array for an electrified machine is provided. The battery array includes a plurality of individual battery cells, or groups of battery cells. A plurality of cell monitors are in communication with the individual battery cells, or groups of battery cells, with the plurality of cell monitors being powered by the individual battery cells, or groups of battery cells. A battery controller of the system receives information about the individual battery cells, or groups of battery cells, from the plurality of cell monitors. The information traverses the plurality of cell monitors in a first pattern to the battery controller and, after a predetermined period of time or occurrence of a predetermined event, the information traverses the plurality of cell monitors in a second pattern that is different than the first pattern to the battery controller.
