A battery pack has first and second battery terminals, plural battery cells each with a battery element, a cell supervisor electrically connected to the battery element, and a communication section to communicate with the cell supervisor. The battery elements are connected serially between the first and second battery terminals. Bus interfaces are arranged in alternating fashion with the battery cells to define a daisy chain bus, each such bus interface being configured for signal communication, the interfaces respectively connecting the communication sections of two adjacent battery cells. A battery manager communicates with the battery cells via the daisy chain bus. The battery manager sends a command message to the battery cells using a through mode protocol, and each battery cell sends at least one of a confirmation message and a service request to the battery manager using a shift mode protocol.
