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.
You do realize SLA will also potentially energetically vent when punctured?

Few battery chemistries will let you store significant energy and be happy when you dead short them internally (and SLA isn't one of them).
