Perhaps ask the AHJ what a listed box entails? I have presented numerous AHJ's with a multitude of boxes and never had any questioned. Vent with fan, inlet air on diagonal lower side from fan, sloped top, minor containment, clear Plexi glass top, jug of neutralizer = no issue

I agree, Brian; especially when the battery system is large. It's important to design the room so it can be in compliance with NEC 480.9. (A) Ventilation, (B) Guarding live parts. The locked door qualifies, and (C) Working space.
