Battery assembly for battery powered portable devices

摘要

A battery assembly includes at least a plurality of battery cells that includes at least a first and a second battery cell each attached to a distributed battery monitoring unit, the second battery cell being associated with an external circuit, the second battery cell connected to a battery management unit (BMU) by way of a pre-formed battery contact shaped to accommodate the external circuit. The plurality of battery cells are electrically connected to at least the BMU such that each of the plurality of battery cells are substantially aligned with each other thereby preserving a battery profile corresponding to unconnected battery cells.
