The types of battery OP linked has internal protections and a fuse (in this case a 25amp internal one) that keeps it pretty safe.

Like i said LiFepo4 is safer then LiPo but I still wouldn't trust high school kids with ones without a built in BMS/etc. And I don't now of any pre-made packs 12v 10-15ah that can handle the 200amp burst current FRC demands for a reasonable price.

The A123 packs I've put together/the ones you generally find in battlebots (like tombstone) are just raw cells wired together connected to whatever. Would not trust students with these.
