LOL, sorry to make your head spin. I belive what the flashligh folks are talking about the driver cicuit in there LED flashlight. Did I mention I am a flashlight freak? If there was a clamp in the Li-ion batts how could I test an atty under load at 3.95v when the working voltage is 3.7v?
Well from what I know, normal Li-Ion batteries are nominal 3.7, with a peak usually of 4.2. Li-Ion batteries don't tend to suffer as much of a voltage drop under load as non-lithium batteries, so 3.95v sounds perfectly reasonable to me under load of an atomizer. In fact they tend to hold their voltage high for quite a long while before the curve begins to drop significantly (and then the voltage curve plummets). In fact, in my personal experience, by the time you even get down to 3.7v (resting) you have already used more than half the capacity from a full charge.
My confusion I think is more with the "3 volt" Lithium batteries - as far as I know, a single cell is typically nominal 3.7v, with a typical working range of 4.2 down to 3v. (You can go lower, but you shorten the battery life in doing that..in fact some people who use separate circuits for cutoffs are using 3.2v as the main cutoff now i think.) Anyway, so I understand how a nominal 3.7v cell can be reduced to 3.0v with a regulator.. the part that has me baffled is how one would do that without one.
I'm mostly going by personal experience here with Li-Ion and Li-Po batteries.. but I have not until the past 6 months used any "3v" lithium batteries (or had even heard of them). So, how would one make a "3v" lithium battery that does not use a voltage regulator to do so?
