I see all kinda of threads and info about lipo batteries blowing up, burning up, catching fire etc. Do I really need a bag to keep the battery in while charging and storing? I'm looking for a no BS answer here. I see way too many topics across the internet riddled with "they will blow up!" and the like. It reads like paranoia and really makes it seem like using lipo batteries is a waste of time because they have problems.

So how much actual precaution is really necessary?
