Here is my first attempt at a battery box w/ ventilation.
This is an off grid system, the primary function is to run the well and pool pumps.
Thus, the batteries do not get much use, so little gassing.
Box is Lexan, sealed w/ 3M weatherstrip foam & 5200 polyurethane sealant.
Fan is run by the inverter AUX terminal strip, so if the inverter fails, the fan stops.
Vent is to the outside.
I sealed all the cracks and crevices, so that there is no leakage into the room.
