A battery system may include a battery pack including a direct current to direct current (DC/DC) pre-charger and a battery cell. The battery pack may include a positive terminal and a negative terminal of the battery cell electrically connected to a first positive bidirectional terminal and a first negative bidirectional terminal, respectively. The positive terminal and the negative terminal may be electrically connected to a positive output terminal and a negative output terminal, respectively, via a positive electrical connection and a negative electrical connection. The battery pack may further include a high voltage bus bar electrically connected to the positive output terminal and the negative output terminal and a communication bus bar electrically connected to the DC/DC pre-charger. The DC/DC pre-charger may pre-charge the high voltage bus bar and/or discharge the high voltage bus bar via a second positive bidirectional terminal and a second negative bidirectional terminal.
