My take on the design of the Stainless enclosure is that the top was not "sealed"
There were too few fasteners, (screws) and the top was "unhemmed", (not doubled). Nor did I see any remnant of gasketure. Nor fasteners bearing down from the top....
The penetrations likewise seemed unsealed, though there appeared to be "grommets" to prevent abrasive wear...
The case appeared to communicate (pressure wise) with the EE bay as a whole, any sealing attempt would have made pressurization of the Battery enclosure separate from, and more difficult, than pressurizing both at once.
