No, but they have corrosive alkaline and alu eating electrolyte, can overheat and short and boil, spilling the electrolyte all over.
Agreed. Anyone who's lifted the lid of a nicad after brisk charging will see
evidence of electrolyte and the fumes to go with it.
In this case, I wonder if the so called fan in that enclosure is there for cooling, or primarily to exhaust the corrosive gases ?.
My point is that the basic architecture is the same, implementation is common practice in aerospace.
Electronics and cells of any type don't mix and just because it's common practice,
doesn't mean that it's correct, nor that it isn't just wrong by design
. Everyone
else does it, so it must be ok, right ?.
Designers must question everything, especially their own assumptions and those of
the people they most respect...
