It comes down to what happens when a protection circuit board (pcb) fails on a protected battery. They can flame out if they fail whereas a Safer Chem is not supposed to flame. They can both be dangerous. Here is some common sense tips that may help calm those nerves.
-be careful with your batteries. If you drop them or damage them, safest bet is to toss them.
-get a multi-meter. this is helpful for when you forget to remove your battery. check them to make sure they're not overcharged. also a good tool if you are having a problem with atties/cartos. we can help you learn how to use it. its really easy once you've done it a couple times.
-mah ratings can be deceiving at times and at others...flat out lies. For instance, I would be very skeptical of something that claims to be 3600 mah as it pertains to an 18650. When asking folks about how well their batteries perform, it might help to get a guestimate of how many mls as opposed to how many hours one goes through on a battery charge. Even though we all vape differently and LR vs SR will make a difference as well, the most common way of quantifying vaping time is by mls/charge....from what I've observed. Some may disagree.
-and last...take your time. keep asking questions until you feel you've gotten a better understanding. heck, there's still stuff I don't quite get and I'm not worried about it. I defer to the experts if I don't know.

someone will eventually come along with an answer that makes sense to you. that's why I love these forums!
