I have used high capacity (up to 63V/65 amps constant with bursts over 100) lithium based chemistry batteries for over 10 years, since the very time they were made available, at least for radio control aircraft hobby.
It is my personal experience that the safety concerns are way over rated regarding their use.
I have on purpose abused such batteries in every way i could think of in order to find out how much i should be concerned, how much truth or fiction is there since it seems to me( in most aspects of life) there is so much ignorance in the world.
Most people take for good a lot of hearsay so to speak and few have the curiosity or the means to experiment.
Of course the industry doesn't want any accidents. Nor do the users for that matter.
But i believe it is the industry who suggests very conservative parameters and even scares away the people.
A battery, regardless of its chemistry will give only as much juice as it can. It doesn't much care. It will get warm, it might vent, it might suffer damage as in shortening its life span.
As far as vaping, the batteries are used on short bursts, not under a constant demand as in for example doing 3D aerobatics with a RC helicopter.
From my experience i would say charging at a lower rate using a decent charger(even though they might be rated to higher C for charging), not over discharging and giving them a little rest after use, and prevent them from shorting (as they will blow up and catch fire) will prolong their life.
Don't succumb to paranoia as many uneducated people do.
As Nach, i use .8 ohm coils with good success in 18350 batteries.
Phew! Rant over.
PS. Just for refference, here is a camera heli with a 2 meter rotor span with 2/10S, 10 Amph Thunder Power(500$ a pop) lipos and a bunch more auxiliary ones.
The 2 main batteries under the main gear.
