Br I see what you're doing now, since there is no liquid near the battery connector, can't you just drill an air inlet hole on the bottom side of the carto like a 901? There is no law that says that the air has to come from the battery itself, and with many manual batteries having the silly auto-battery hole, it would be even healthier if it didn't come from the battery
yes that would illiminate the need for the bottom stem airhole, it then can flat and be sealed so no worries of juice splatter to the batter area.
br , dont upset the cheetos gods, take a 3 hour nap max then get back to work, oh and eat something.lol
