I dont know, I kinda like the “not for beginners”, it may keep people on the trail from blinding me like I accidentally blind them at times
I just look at it as a risk assessment and figure out what the risk is, and what you can do to lessen each risk.
First off, the risk is extremely low: How many hundreds of thousands (millions/10s of millions) of cheap batteries are sold online so far? I live in America, news organizations would fall all over themselves to tell us if even one person died from a Li-ion battery exploding…yet I don’t hear about this, and when I search and find a story about an “exploding” Li-ion, it usually ends up being a “outgassing” battery, more of a pressurized flame, not an explosion. I have found one story with a bad cell phone battery that exploded and killed a guy…a cheap copy Chinese battery…the rest are “near misses” and when you dig into the story it seems they all have a common thread: cheap batteries and a warning sign that is ignored. So: I charge when I’m around in the kitchen, I monitor my batteries for temperature/flashlight runtime (hand on light for temp is common sense), not use cheap Chinese batteries, use protected batteries to prevent over/under charge and occasionally check with a voltmeter when possible as an added precaution. Since I’ve never heard of anyone doing this being killed or maimed by a Li-ion in a light, I think its an acceptable risk, but there is STILL a risk, but its very very small. And, there is risk with almost every choice you make. Probably hiking in the dark without a powerful light could make me come across or be vulnerable to higher probability dangers than with one, all things considered.
Now even though they dont seem to really literally explode often, its pressure we are playing with which can make a grenade, I’ve seen pictures of what parts of the light in an exploding light do to metal objects they hit and I like multi cell lights best, so again: I only use protected cells, no Chinese cheapos, I monitor and I will know when my battery run time decreases because I tend to time my hikes/walks and notice if I’m left with a dimmer light (or in the dark), I open and re-check a light I haven’t used for a bit to make sure of battery alignment. As an added precaution I try to check them with a voltmeter when they come off the charger, especially as they age. The only other precaution I could see to take would be maybe drilling a small hole in each light so I have a possible flamethrower instead of a metal projectile if all other precautions fail.
All in all its a tiny risk, but I still try to minimize it, and then don’t really worry about it after my precautions. One is probably millions of times more likely to get hit by a car fiddling with your light as you cross the street than having one blow up, but I still cross the street (while aiming the light in the general direction of oncoming cars as I cross). So I understand both perspectives: yeah the risk is so low one can downplay it, since many daily activities you do are more likely to get you killed, but I would say you should always warn people of any risk you know of, and I’m not going to completely ignore any risk of serious injury I can do something about, but minimize what I can with reasonable effort and certainty (drilling holes in my lights = meh…but the rest, of course).
