Abstract
A system and method are disclosed for charging battery packs. A battery pack connects to an external battery charger. A processor of the battery pack recognizes that the processor is connected the external battery charger. The external battery charger provides charging parameters to the battery pack. The processor sends charging parameters to the external battery in response to recognizing that the processor is connected to the external battery charger.
