Prevention is better than cure though. plus you've got to consider cell gassing/venting/explosion risk/toxic fumes as well as fire prevention.
If they were doing per-cell protection, fair enough (cheap 18650's don't have cell protection usually), but I think they are still connecting 4 cells in parallel, with only serial-bank MOSFET's like in usual sealed packs.
