Really, only experimentation will tell the story. The higher the discharge

Not to be glib, but that's why I asked the question. "Hot" is a
relative term - more than room temp, to hot to touch, etc, etc. So how
hot is too hot? I had hoped there was someone who could point me to a
spec sheet on these things since experimenting at $38 a pop is not
good.
My battery charger somehow senses battery temp since it has a mode
"Charging delayed - battery hot", and I have seen it go into that mode
when the battery case only felt lukewarm in the hand.
