As pointed out...the main reason is the Lipo's are far more dangerous when they go. I've not personally seen a Lipo go, but from what I've read they give anyone a reason to talk (or post) about. A venting C is a bit less impressive. I read this just yesterday...the person reporting on a TC5 tips and tricks had one go (MaxAmps). It took a bunch more equipment on his bench...and this car...I'd be bitching too!! Never seen a nihm come close to that much damage.
