So I've been running some IMR batteries for my 18650 lights (except for those that came with their own cells) that I picked up on Amazon a little while back. I really prefer the safer chemistry of IMR cells, in fact I rather prefer to avoid li-ion flashlight batteries as much as possible. Yes they do have significantly better performance but I just don't like the risk of a bad cell going poof. I just don't trust all these online retailers to supply good cells, not to mention all the Chinese made chargers. Am I being foolish and paranoid? After all, pretty much all of my lights run either AAA or AA nimh LSD cells with the exception of a Malkoff M361W/nichia, a Zebralight and a Armytek. What am I giving up by going with IMR cells? What are good brands these days?
