Ok have been using my bath type cell for 4 months now with a 4 plate design = -nn+.
and have pics of the PVC container and plates after that time.
And the biggest problem(why I removed it) was that one of the SS straps i use from bolts to plates corroded or burnt off due to bad contact, caused by a loose bolt, as seen in one pic - looks like it heated and melted.
but the electrical tape stayed on the straps - not the plates.
will be going to dry cell like painless.
As always - would like feedback, thanx D
