A battery pack for a direct current (DC) voltage bus includes a battery disconnect unit (BDU) operable for controlling a connection state of the battery pack with respect to the DC voltage bus, first and second battery sections, and six transfer conductors, e.g., busbars or cables/wires. The first battery section has first and second battery modules with corresponding battery cells. The first and second battery modules are connected in series. The first and second battery sections are connected in parallel. The second battery section has third and fourth battery modules each with additional battery cells, with the third and fourth battery modules connected in series. The six transfer conductors collectively interconnect the battery modules, sections, and BDU. A total battery current is divided equally between the battery sections, with the transfer conductors being rated for half of the total battery current.
