Energy storage devices, battery cells, and batteries of the present technology may include a first circuit board characterized by a first surface and a second surface opposite the first surface. The second surface may include a conductive layer. The batteries may include a battery stack overlying the first circuit board and electrically coupled with the second surface of the first circuit board. The battery stack may include a plurality of battery cells. The batteries may include a second circuit board overlying the battery stack. The second circuit board may be characterized by a first surface and a second surface opposite the first surface. The second surface may include a conductive layer, and the battery stack may be electrically coupled with the second surface of the second circuit board. The batteries may include a power distribution block electrically coupled with the first and second circuit boards.
