I will state the obvious. Li-ion batteries are inappropriate for vaping. Not only are they a danger to those who use them, other peeps in their vicinity are also put at risk. And they are a risk to property, public and private. For those wanting to ban ecigs in public places, the danger of Li-ion batteries is certainly a valid reason. I won't go door-to-door evangelizing, but if the subject comes up, I would suggest to anybody using Li-ions that they would do better to use NiMh. I would certainly never give a Li-ion powered ecig device to anybody I cared about, especially to old peeps.
I will anticipate some of the rebuttals:
Here [in] the United States of America, land of the free and home of the brave, we have the God-given right to vape with Li-ion batteries.
Other types of batteries, notably NiMH, are not powerful enough for vaping. Too big and too heavy.
We can't abandon Li-ion now because the whole ecig infrastructure is built around them.
So what if a few dozen peeps a year get hammered by Li-ions? They get what they deserve for not learning and scrupulously following the rules of battery safety.
We use Li-ions in our phones, tablets, and notebooks. You want to ban those too?
I expect all the rebuttals will be similar bullcrap.
I haven't read all the replies in this thread, but I would not be surprised if some fool suggested that we should [not] publicize battery mishaps because it might give the government ammunition to use against us. I have seen that suggestion in other similar threads.
