Abstract: A battery pack and a method of arranging battery cells therein. The battery pack includes a plurality of battery cells arranged and wired together to produce a suppressed or reduced magnetic field. The battery cells are arranged so that the positive and negative terminals of adjacent cells are alternated. Wiring connecting battery cells in pairs is twisted to minimize the area of the current loops in the battery pack. Wiring between battery cells that are adjacent each other is arranged to carry equal and opposite currents. The alternating terminal pattern and the manner in which the battery pack is wired results in the magnetic dipole moments of adjacent battery cells partially or fully cancelling each other out. The battery pack is suitable for use in Unmanned Aerial Vehicles (UAVs), Unmanned Underwater Vehicles (UUVs) or space-limited applications or devices, and makes it possible to use magnetic sensors in these devices.
