Abstract: Embodiments include a portable rechargeable battery pack, system, and external adapter that allow the portable rechargeable battery pack to both power a host device though a set of host contacts and provide power through a set of charging contacts. The portable rechargeable battery pack includes a charge protection circuit that prevents an excessive discharge current through the charging contacts and allows high charge current when charging the portable rechargeable battery pack. A discharge circuit allows a low level discharge current through the charging contacts to provide power to other devices.

Abstract: A method and apparatus for detecting and responding to cell swell in one or more cells of a battery includes receiving one or more indications of cell swell from switching circuitry associated with a cell, determining if the battery is fit for purpose based on the one or more indications, and performing an action responsive to the one or more indications and whether the battery is fit for purpose.
