Abstract

A battery pack and transport coupler for enabling the battery pack to reduce the pack power capacity. The battery pack include a plurality of strings of battery cells and a switching network for coupling and decoupling the strings of battery cells from each other. When the plurality of strings of battery cells are coupled together in a default configuration the transport coupler includes a decoupler for decoupling the strings of battery cells and when the plurality of strings of battery cells are not coupled together ina default configuration the transport coupler includes a coupler for coupling the strings of battery cells for operation with an electronic device such as a power tool.
