Non-regulated devices can have battery protection as well, (think fuses) the average one simply doesnt. Yes, I think they are among the most dangerous mods out there, but safety comes with education, and those who educate themselves should be fine. Problem is that NOTHING requires anyone to educate themselves first, and many people simply wont be bothered. I see our biggest challenge in trying to protect the new user, the one who doesnt know an ohm from an Amp, but he wants to quit smoking, and he wants the most powerful device he can find. How do we protect that individual? 50% of people wont even read the instructions, let alone about battery safety.
There are a multitude of different capacity C3 batteries out there, and all of them fit the same tools. Besides, whats wrong with matching a battery to a load. Some people like 18500s, other like lipos. I just think they BOTH should be protected.
See Appendix I in this for 3 pages of headlines that generate public hysteria against vaping:

Its actually a decent appraisal of ecigs considering it was issued by the government.
It doesnt matter whether it was "stupidity" or hardware failure. The press gets a hold of it and sensationalizes it. Then politicians jump on the bandwagon trying to restrict it. Safety need to be inherent in order to minimize the Headlines..........
