Abstract: A power supply for use in a portable electronic device is described. This power supply includes battery cells in separate locations that are electrically coupled by a power bus to a battery-management circuit board, which includes an integrated circuit with control logic that monitors the battery cells and that regulates charging and discharging of the battery cells. The battery cells are not enclosed in a common battery-pack housing so that the battery cells are mechanically separate from each other. Moreover, the battery-management circuit board is external to the battery cells and is not enclosed in the battery-pack housing. By excluding the battery-pack housing from the power supply, there may be more space available to expand the sizes, and thus the total capacities, of the battery cells.
