A rechargeable energy storage system includes a DC-to-DC converter operational to: receive a battery discharge power at two first local nodes; and convert the battery discharge power to a pack discharge power at two first inter-assembly nodes while in a discharge mode in response to a control signal. The DC-to-DC converter is further operational to: receive a pack charge power at the two first inter-assembly nodes; and convert the pack charge power to a battery charge power at the two first local nodes while in a charge mode. A first battery assembly has a first state-of-charge. A second battery assembly has a second state-of-charge, and operates in series with the first battery assembly. The controller is operational to generate the control signal that varies the DC-to-DC converter to balance the first state-of-charge with the second state-of-charge while in the discharge mode.
