A battery balancing method for balancing voltages of battery packs on a bus bar of a utility vehicle is disclosed. The method includes determining, by a control system, a state of charge for a first battery pack and a second battery pack of the utility vehicle, initiating converter battery balancing, by the control system, to discharge the first battery pack to the second battery pack through a DC-to-DC converter in response the first battery pack having a state of charge that is more than a first threshold amount above a state of charge of the second battery pack, and initiating direct battery balancing, by the control system, to discharge the first battery pack to the second battery pack in response to the first battery pack having a state of charge that is less than the first threshold amount above the state of charge of the second battery pack.
