as for venting for gasses.
is this gas lighter than breathing air? thinking hendenburg.
as where my batt's live it is mostly open under them . so a upper vent is worth it.
Yes, hydrogen is lighter than the atmosphere. FLA Batteries produce a small amount of hydrogen when charging. That could be when on the road and the tow vehicle's alternator is providing power or from RV mounted solar charging. Since there is very little volume of hydrogen produced, a large vent hose isn't needed. It does need to be at the top of the enclosure and a make-up hole installed close to the bottom of the enclosure for proper air flow.
FWIW, I use a Xantrex 1000W pure sine inverter to power a small fridge. The fridge draws 80w, operating, and probably 5-7 Amps at start up. The Xantrex doesn't break a sweat. Now, I have a Tripplite 2000W unit that I am going to install. I haven't decided if I will keep the Xantrex or do a full transplant with the Tripplite.The power saving feature of the Tripplite is a good advantage for watt squeezers like myself although the Xantrex only draws < .5 amp when powered.
