Neither are ideal but I will take a NIXX exploding any day over a lipo that goes up in flames. Not only is the NIXX much, much less likely to start a fire but it also does not have the caustic smoke associated with a lipo fire.

Now with all that said I do not charge in a lipo sack. My only point in arguing with you is that in your original post you seem to think that lipo issues are user error. Plenty of reports on the web to show that is not the case.
