There is at least one brand of exterior vent intended for battery venting. I installed one on a previous TT. It has a mating piece on the inside for connecting a standard 1-3/4" battery vent hose. Not sure what brand(s) these are - Valterra, MTS products, JR Products, etc. I bought our vent & hose at a local RV dealer. The one in this photo is on ebay:
