Well said. I've never seen any warnings with mods that can take 2 stacked 18350s yet one should always be careful when doing this. Anyone can buy these mods and throw in whatever they have lying in a drawer. Does that make them stupid? No, they just didn't get the information they needed. I even wouldn't call it ignorance. When the average Joe buys a piece of modern technology he just expects it to work and be safe without having to read up countless pages on forums.
For the most part its always users error and most regulated ecigs are plug and play, manufacturers do drop the ball sometimes like the groove. Cell phones explode, walkie talkies explode, ecigs explode, the batteries are that powerful and when used improperly or severely damaged, ya.
There some electronics gurus out there, here on this forum building some of the safest mods you can buy. Even with all the safety bell and whistle, user error can damage even those built above and beyond common manufacturer protective measures on regulated mods.. A mechanical mod 100% is all user input after purchase-----.
Sorry to hear about those two guys it happened to and the B&M's cannot police each and every sale.. When most people buy a mod I would assume they are aware of the batteries they need.. If that B&M sold the mods to people without asking, are you aware of the proper batteries or handing an instruction pamphlet? then maybe they should be held responsible.. IDK its so new of a production, vaping, some protocols need to be set in place and employees trained. Maybe the guys thought themselves smarter than everyone and no its ok to use that battery since using two at a time woot more power IDK..
I do know when cell phones explode; that have hit the news, it's been a bootleg battery as the cause. Case in point here, both cases= wrong batteries..
Remote control guys/gals have been using li-ion lipo batteries for a long while now and using them safely, explosions do occur when mishandling or in epic crashes but its rare.. Our ecigs are 100% more safe than most remote control vehicles. I have been into r/c for almost 20 years and not one of my batteries have exploded so do not be afraid, educate yourself if you use an ecig.. I look back at how I treated my r/c batteries before I knew battery safety recently and laugh at my stupidity..
Clones have exploded as well as name brands but again usually the wrong charger was used or sold to them by mistake -- its been user error 90% my knowledge of it except for those groove units, that was a design flaw..
