a set of pressure-relief valves positioned in and protruding through a wall of the first portion, wherein:
each valve in the set of pressure-relief valves is configured to provide a fluid path from the enclosed cavity to environment outside of the battery pack when pressure inside the enclosed cavity is at or exceeds a set threshold,
the enclosed cavity is fluidically isolated from the environment when the pressure inside the enclosed cavity is below the set threshold, and
each valve in the set of pressure-relief valves is coaxial with one gap in the set of module gaps.
