I think the title pretty much says it all.
"Are lithiums safe as long as they are not in series?"
I've read many, but not all of the threads in this section, and it seems to me that the problems with lithiums and fires, occurred for the most part, years ago, and more often than not when two batteries were put in series.
Further the problems with batteries in series occurred when the batteries were of different capacities, and or charged to different levels.
Some threads or at least individual posts suggest that with the advent of protected cells, there isn't much of an issue anymore.
Its my understanding that one still needs to be aware, when charging an over-discharged battery that there may be a fire, but that should be a concern only after it has been depleted to the point that the over-discharge protection circuit has tripped.
I only have one light that I use CR123s in series, (it won't fit an 18650) and won't buy another due to the fire concern. Am I correct about about being concerned?
