This is very exciting news! I love the 14500 size because I have a ton of AA/14500 lights that can use this. I have a number of Sanyo 14500P but always wish the capacity can be higher. This will help a bit. What cell is under the wrap? Surprise it can beat the Sanyo in energy density.
Also, did you send the Sanyo NCR21700A to HKJ for testing? Really like to have that on his comparator. It seems to be the best 21700 for most flashlight use cases unless very high current is required.
This is not a protected cell, it has no electronics that prevent overcurrent or overcharge/-discharge. The PTC is a one-time fuse that will blow in case of a direct short, all li-ion cells from major brands have that.
(vapcell) Thanks for stating the obvious and the offer of making something happen if needed. I have never witnessed such hostility on this forum to the protected cell form factor. As folks are heaven forbid injured moving forward it will unfortunately be difficult to spotlight but not hard to explain.
Thanks for endorsing progress here Dennis. Me and others would also have liked a higher drain cell, but thanks anyway. The pricing is fair also. :THUMBS-UP:
The only 14500s I bought more than a couple years ago are installed inside a li-ion converted hair clipper LoL! :-D
I don’t know how big the 16340 market is, but I was just buying new batteries and there was not much to choose from. So I’d appreciate if there were some (new) good 16340 cells.
