I have not checked recently on the Juice brand, but in the past I chased the R CR2 aspect pretty hard, as I was working on a CR2 based light for a while. (The Breeze light in my sig line)
The AW protected R CR2 cells were the only ones that were fully protected.
The Juice cells - at least at that time, had very limited protection. I cannot remember the details, but I decided that they had too much liability for my taste.
That being said, the good news is that the Li content of a R CR2 cells is relatively low compared to a R 123 type, so I suppose in theory, the extent of damage from an "event" is probably lower.
An "indication" of this (not proof) is that there have been a few CR2 lights that discharged the cells at 5C, and the failure mode was consistently "not holding a charge", vs "event".
If I were going to use a "not fully protected Li Ion CR2 cell, I would use them not more than 5 cycles and toss them. They aren't that expensive relative to primary CR2s.
