Relocating Batteries
I am moving my pair of Costco Golf Cart Batteries from the tongue, to the rear of the camper under the bunk area. Primary reason is to get my tongue weight down a little bit. I've done all the calcul...

That MTS Products sealed & vented battery box has an intake on the bottom. In fact, the upper and lower pieces are identical. Many FW trailers use this same MTS box and they all have the intake extended into the space below the front storage compartment and the exhaust vent is a foot or more above the top of the box. If that's what RV manufacturers do, that's what I would copy. I installed a vented & sealed battery box in our last TT, and after doing a lot of internet research, I ended up doing basically the same as what FW trailers do.
The exhaust vent should be min. 6" above the top of the sealed boxes. I can't find info. on the internet at the moment that discusses this but I have found it in the past. I don't see how hydrogen and air can flow out the single upper vent without an intake (in the correct location). If there is tech. info. on this on the internet from a credible source, I'd be interested in seeing it. Under some temp. conditions, the hydrogen will just sit inside the box so it's important to have the venting right.
It's also important to keep the battery compartment adequately vented and cooled so the batteries do not reach 100 degrees F for sustained periods otherwise the batteries can potentially overheat and go into thermal runaway with catastrophic consequences.

I dunno... IMHO, you need to make ventilation improvements. Nice work otherwise!
