    Abstract: Energy storage devices, battery cells, and batteries of the present technology may include a first circuit board defining a plurality of apertures through the first circuit board. The batteries may include a battery stack overlying the first circuit board and electrically coupled with the first circuit board. The battery stack may include a plurality of battery cells. The battery stack may define a plurality of apertures axially aligned with a corresponding aperture through the first circuit board. The batteries may include a second circuit board that defines a plurality of apertures through the second circuit board. The batteries may include a plurality of fasteners, each fastener extending through a separate channel of the plurality of channels. The batteries may include a plurality of conductive extensions electrically coupling each battery cell of the battery stack with one or more fasteners of the plurality of fasteners.

    Abstract: A busbar for a battery module includes a first portion configured to be coupled to a first terminal of a first battery cell, a second portion configured to be coupled to a second terminal of a second battery cell, and a fuse portion extending between the first portion and the second portion. The fuse portion includes a number of openings extending through the fuse portion. Each pair of openings defines an electrical path between the first portion of the busbar and the second portion of the busbar.
