A powered system has a charging system and a controller arrangement. The charging system is capable of recharging the multi-cell power supply for the system and the controller arrangement enables selection between alternative modes of operation of the system. The charging system is arranged to operate in different regimes in which a target charging voltage across one or more cells or batteries is set to a different level dependent upon the selected mode of operation. There is provided a mode for optimizing the battery management for maximum range or, alternatively, a mode for extending charge and discharge cycle life of the multi-cell power supply. There is also a storage mode where the target voltage is set to a minimum value.
