I would add that 'Non defective' Lithium Ion batteries packed and handled correctly are not a hazard. Experience in other applications has show that manufacturing problems can cause issues. Another unknown to add to the list.
The point of correct packing and handling is that defective batteries with cells short circuiting and going rogue (not normally possible when not in a circuit) are isolated and do not cause any other batteries to fail.
