Do I have to use expensive, vented battery boxes & vent tubes & vent caps….., to vent 2 batteries I want to mount in the cabinet of my popup, or could I use a vented access door like the one behind my 3-way fridge? It seems to me it would offer more ventilation than a vented battery box & I could line it with screen to keep out insects. I could replace the latch with a lockable one & this would give me access to charge even when closed down. I have to mount the two 27 batteries, I just impulsively bought (because of a sale), closer to the axle because I will be over my tongue weight limit if I mount them out front. I realize I still have to use regular battery boxes or trays inside to keep the batteries from bouncing around while traveling. I’m 90% sure I’m confident in doing this, but I’m also not an expert on venting batteries so I don’t want to blow anything, myself or anyone else up!

Hi did you buy lead acid or agm? Lead acid you will need to vent with box, tube, vent or big door.

AGM battery does not need vents and can be charged on your sofa.   

Very happy that you understand weight limitless and tongue weights.
