Abstract: Apparatus and associated methods provide an intelligent battery pack interface module for mounting to an electrochemical cell assembly and having circuitry for establishing electrical connection with the cells. The circuitry may establish electrical connection in a parallel or series manner, for example. In an illustrative example, the circuitry may provide control and management operational functions. In some examples, the module may include a base and cover which cooperate to form a housing, where the base may include an alignment structure for alignment with cell terminals. In some examples, the circuitry may be located within the housing. Various examples may include handles extending from the module. In some examples, the handles may automatically retract upon release. The handles may retract to present a low profile so as not to interfere with connection of the module to a cable received in a plane substantially perpendicular to a gravity vector, for example.
