Abstract: In a general aspect, an electronic device can include a first battery cell, a second battery cell, a system power bus and a system load coupled with the system power bus. The device can also include a first bidirectional controller that is operationally coupled between the system power bus and the first battery cell. The first bidirectional controller can be configured to control a charging current and a charging voltage of the first battery cell, control a discharge current of the first battery cell. The device can further include a second bidirectional controller operationally coupled between the system power bus and the second battery cell. The second bidirectional controller can be configured to control a charging current and a charging voltage of the second battery cell, and control a discharge current of the second battery cell.
