Guarantees? None. That why I mentioned that the protection electronics need to work to...umm...work.
Yet, despite this, I can still see a lot of people trusting the protection electronics thinking they [these protection electronics] are safe enough that the person who uses the device in question factually should not have to experience the need to start caring about general rules of battery safety even though they obviously should care, but
to them it's not so obvious the fact this should be obvious, particularly when it comes to understanding the need to educating theirself properly, as well as to passing on correct knowledge to others. Worse, I can still see a lot of people who dispute this being a real problem, even, and BTW not all of them are salesmen or marketing specialists. The whole 'protection' buzzword stuck. And it is causing people to fail to protect their own self responsibly. The perpetuated misinformation that surrounds regulated mod general safety is.
With mechs you however get the advantage of your charger turning itself, and perhaps several cells, into a nice fireball while you are sleeping next to it on the couch. This is not an unheard of event. And there are some very real safety issues with mechs, just as there are with regulated devices.
Yes, but by definition alone, external charger issues are issues that are external to mech mods. Only the human factor links the two together, technically speaking, and, with mechs you get the advantage of not having to deal with the vagueries of some Chinese chipmaker so, about that human factor and how it relates directly to human safety knowledge, I personally believe that,
for me, simple electromechanics subjects about mech mods are far easier to understand and work with when it comes to dealing with battery safety
use.
Neither regulated or unregulated mods are inherently better or safer. It depends entirely on the individual device(s), their design and condition, and how it/they are used.
I know. Now, the only real challenge is to try and convince people that this is so─and believe me I have tried.
