some points to note here:
The two gasses emitted from a charging Lead Acid battery are hydrogen and oxygen. neither of these is corrosive to unprotected metals. Oxygen will cause accelerated oxidation that's all.
Both flooded and AGM batteries will emit gasses under certain circumstances, that puts them in the same category.
the corrosion you see on posts is due to acid VAPOR condensate, usually a product of overcharging.
Lithium is another story altogether. they self destruct rather too quickly to worry about gasses.. !
FLA's should not be charged in a sealed container, a well ventilated container is ok, a purged container even better.
I have an inverter located in a battery pack of my own RV, the box is purged with a fan and poses no reasonable threat. as a precaution ( and I'm a little anal with these things ) I fitted a sensor to the fan that will disconnect the main breaker should the fan fail. So this is possible if the necessary precautions are taken to mitigate the gasses. I do this myself as I understand all the issues. for a less technical enthusiast I would say not to do this..
