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.
