Abstract
A portable information handling system battery module has a self-contained housing having a battery charger, integrated rechargeable batteries and plural ports to transfer power, such as USB Type C ports having bi-directional power transfer capability. A cable couples first battery module port to a portable information handling system port to provide power to the portable information handling system and accept power from the portable information handling system. Plural additional battery modules daisy chain to the first battery module to accept power from and provide power to the portable information handling system. Power transfer is coordinated with communications through the ports, such as by a USB power transfer protocol supported at the information handling system and each battery module.
