Re: Re: bellows on batteries

<<Wouldn't a spring-loaded safety valve(like those used on steam boilers to
prevent overpressure) work better, AND be automatic?>>

I think that would work as long as:

1. It's set low enough so the batteries don't implode first.
2. You run it into the bellows so that you don't pull in air from outside.

Anything else I'm missing?

Just to clarify I'm a lurker on this group who is just exploring this idea. 
I'm way out of my league.  That's why I posed these ideas more as a question.
