Abstract: Battery systems according to embodiments of the present technology may include a battery cell having an electrode tab extending from an edge of the battery cell. The systems may also include a module electrically coupled with the battery cell. The module may be characterized by a first surface, a height, and a second surface opposite the first surface. A conductive tab coupled along the first surface of the module may extend from a first end parallel to a plane of the first surface. The conductive tab may be characterized by a curvature proximate a midpoint of the conductive tab. A distal region of the conductive tab may return back across the first surface of the module substantially parallel to the first surface. A distal portion of the electrode tab may be fixedly coupled with the distal region of the conductive tab.

Abstract: A streamlined battery pack can contain at least two battery cells. A printed circuit board (PCB) of the battery pack can include a protection control module. The PCB can have castellations along its perimeter in which wires are soldered. The wires can include battery power wires and battery monitoring signal wires. The castellations are sized so that the egress wires can be soldered therein without substantially protruding from the outline of the PCB. The PCB has a surface area that is no greater than an end of the battery pack, and thereby need not exceed the outer diameter of the remainder of the battery pack. The PCB and the other battery pack components may be substantially enveloped in a polyimide material. The components of the battery pack, including the PCB can arranged, sized and configured, such that they do not create protuberances in the enveloping material.

Abstract: Battery systems according to embodiments of the present technology may include a battery characterized by a first surface, a second surface, and a third surface. A recessed ledge may be defined by the third surface about a midpoint of the battery. The first surface and the third surface may define a first terrace formed proximate a first lateral edge of the first surface of the battery adjacent the third surface of the battery, and a second terrace formed proximate a second lateral edge of the first surface of the battery adjacent the third surface of the battery and opposite the first lateral edge. The recessed ledge may extend along the first surface of the battery between the first terrace and the second terrace. The battery systems may also include a module seated on the first surface of the battery between the first terrace and the second terrace.
