ahaa....I did not know that, I always figured the caps to burst from the
electrolyte expanding when frozen.
But isn't thermal stress only an issue when it's in rapid concession? I mean
in an outside environment, the temp rarely change more than +-5 degrees C
during 24h. And even then, when having an external casing, you get a thermal
buffer, that makes thermal changes slower.
But are you saying that that doesn't matter?
