Okay, so excuse the jovial pic treatment, but it happened again this weekend - a set of IB's going pop. Luckily the tent in question was empty at the time and no lasting damage was done.
I know we're enjoying more voltage and runtime than ever before, but has the performance/reliability threshold been breached or are we simply using these cells too far outside of manufacturers' spec?
I've seen this happen a handful of times now (though only with IB's) and know of a fair few people with packs where a cell has gone down quite early in the expected lifespan. Whilst the percentage of failures is very small and catastrophic failures smaller still, it seems like it's only luck which has prevented anything serious happening so far.
Any informed opinions/cell experts?
