I see LiPo sacks like any minor safety item, it gives you that feeling of being safe, when you have that wooly feeling, you will make mistakes. The other issue about LiPo sacks, is that you really have no idea on the condition of you cell, whilst it is on charge. So, if you are unlucky enough to be such a big enough dimwit, to seriouslt overcharge your lipo, you may just be lucky enough, that the cell does have it's terminal failure inside the Sack. But I am a strong believer in Murphys (sods) law, and that if there is a chance of a mistake/accident/failure, it will always happen at the most innoportune moment...... like as you pull your Cell out of the Sack, the sack will do no good then, or in your car.....
So, for me, I just think, vigilance, on behalf of all racers, keeping an eye on others charging habbits, and bringing issue's to light, rather than having to use Lucky Dip.... As long as you charge on a CC/CV charger and use a lipo cut-out, these cells are far, far safer than the NiMH mini-grenades.
