Show Me Your Battery Boxes

[Paul & Deb]

Hi John - If you have access to a marine supply place, they will have "thru hull" flanged fittings of exactly the hose diameter that you need. BTW . . . we obviously approach these things in a similar manner . . . good discussion!

Oh, I like those! If I get the white plastic boxes from Century Plastics, which is the direction I'm leaning, I will get those for the tops but do I need to do anything else?

Hi Paul - Will you use one outlet vent or two? If your layout works for one, you will need a hose tee, but can probably find one of these at Home Depot or similar. If routing would work better with two outlets, you can get a matching one from Grand Design. (This is what I did for my second battery box).

I would likely join the two boxes with a PVC Tee like my current 2 single boxes. Then I would run a tube all the way to the front and out the existing outlet. If you look closely at the example I posted earlier (here it is again), it looks like that's essentially what this owner did but with 4 separate boxes.

Hi Paul - I would probably try to get the sags out of the vent hose sections between the boxes so that there is a constant upward slope towards the outside vent . . . but, other than that, this looks like a viable plan.

Thanks, Rob. Might be overkill, but those will certainly do the job. Farm supply stores like Tractor Supply also carry those for use with poly water tanks.

Best,

Paul, I copied your system to vent my two 6v batteries. Each is in its own box. I cut a hole in each box top, inserted a pvc drain flange in the hole, then clamped the hose to the flange, brought the hoses together with a tee, and vented it out using the built in exhaust to the outside.

To vent a home Depot box, black with yellow snap lid, I used white PVC drain fittings. The stuff for p traps and sink drains. I used a sink tail piece and an extra slip joint nut to sandwich the tail piece into a hole drilled into the top. Same with bottom of box for down vent.

Or you could get AGMs and you don’t have to worry about venting.
