A mobile diagnostic imaging system includes a battery system and charging system. The battery system is located in the rotating portion of the imaging system, and includes one or more battery packs, comprising electrochemical cells. Each battery pack includes a control circuit that controls the state of charge of each electrochemical cell, and implements a control scheme that causes the electrochemical cells to have a similar charge state.
