Hard-case LiPos are safer. Right?

[LongRat]

This is my only pack with an injection moulded plastic case. In a hard forward shunt the wires have been pressed into the casing, with hard sharp edges, causing the insulation to be split in both the positive and negative wires. Now they are separated by millimetres with no insulation. I will call this a (very) near miss.



Lithium batteries in cars do not fail by structural rupture or penetration. I have yet to witness any failure that has not been caused electrically. In which case, containing the cells actually presents more hazard. In the instance above, the hard case is actually the cause of the failure.
