a first circuit board defining a first aperture through the first circuit board;
a battery cell overlying the first circuit board and including:
an anode current collector including an anode active material;
a cathode current collector including a cathode active material;
a separator positioned between the anode current collector and the cathode current collector;
an electrolyte in contact with the anode current collector and the cathode current collector;
an opening formed through the battery cell and extending through the anode current collector, the cathode current collector and the separator; and
a seal formed around a periphery of the opening and arranged to prevent the electrolyte from entering the opening;
a second circuit board overlying the battery cell and defining a second aperture through the second circuit board; and
a fastener extending through the first aperture, the opening and the second aperture.
