They are completely uncomparable to "LiPo" cells.

I have personally poked holes in most of them....
A123s are fairly safe, some other Lifepo4's are not as much but when they vent they vent.

The pouch types LiFepo4s also vent pretty energetically, that was what a kid at a local robot event had go off in his bit and he got a face full of lithium smoke (And this was like a tiny 2AH 12v pack).
Sure LiFepo4 it's much safer then LiPo but I still wouldn't trust high school kids with them.
