In one exemplary embodiment, a system in a vehicle includes two or more battery packs. Each of the two or more battery packs corresponds with a battery monitoring system (BMS) that monitors a charge and voltage of the battery pack. The system also includes three or more switches coupled to the two or more battery packs and a vehicle controller to control the three or more switches for operation in multiple modes. In one of the multiple modes, the three or more switches are controlled by the vehicle controller to charge only one of the two or more battery packs with a charger external to the vehicle to equalize the voltage among the two or more battery packs.
