A battery unit comprising a shell made of an electrically insulating shell material, with a plurality of electrically conductive outer pads on the external surface of the shell, the conductive outer pads being electrically insulated from each other; a battery cell within the shell for storing and providing electrical energy, the battery cell comprising an anode and a cathode; wherein at least some outer pads are in electrical contact either with the anode or with the cathode, the polarity of each outer pad depending on its position relative to the geometric center of the battery unit in a referential determined by the direction of an external force, independently from the orientation of the battery unit within said referential. A battery assembly for an electric device, the battery assembly comprising a plurality of such battery units; an enclosure for containing the battery units; an assembly cathode located on a first side of the enclosure, the assembly cathode being in electrical contact with outer pads of battery units that are in contact with the first side; an assembly anode located on a second side of the enclosure opposite the first side, the assembly anode being in electrical contact with outer pads of battery units that are in contact with the second side. A method for providing electrical energy to an electric device, the method comprising the steps of providing a plurality of charged battery units as described above; randomly filling an enclosure of a battery assembly with the plurality of battery units; and applying an external force to the battery units within the enclosure for orienting the polarity of the outer pad of the battery units all in the same orientation relative to said external force.
