$13.50 each, just ordered a couple.
Hope you get them. Iād a problem with an order of some batteries from http://www.sz-eyoung.com/
Basically the cells were returned to the seller by HK post. China post wonāt take them either. Apparently the problem is that the restrictions on li-ions are being rigorously enforced at the moment, prior to a big Chinese government meeting later in the month. I assume this is to do with the formation of the new government next month.
Still, communications with Jone (whoās a member her, I think) was excellent, and my paypal account was refunded. He thinks that things should be better after in a month or so, so Iāll probably spend even more then.
Hank just released his version of protected NCR18650B~

That price is very good, considering how low internal resistance Intl-Outdoorās protection circuits have
To see what I mean, hereās for comparison, IOS vs Xtar, same cell:
Intl-outdoor are keeppower OEM too I think, so they should be the same as the ones at cnqg.
Who knows 
they both have great reputation, and price difference is negligible, so itās a matter of button top (Keeppower) vs raised top (Intl-Outdoor Store) I guess.
They did that when they hosted the Olympics too IIRC.
Got a few from cnq shipped yesterday hopefully they'll make it through.
Hi!
I had done a lot of research on ābutton topā vs āraised topā and even got in touch with HKJ to see what he recommended. His answer was clear and unequivocal. It appears that some high-end flashlights cannot be used with the broader āraised topā and the ābutton topsā are not only compact but they do make good contact with any good spring as long as there is the normal amount of pressure.
I hope this helps.
Regards,
Bob
Raised tops are more mechanically robust though.
Very true.
I also like them, especially in series where the cells are end to top.
Surely button top are better for that?
Do these fit into the Skyray King or any Nitecore Tiny Monster? Experience anyone?
Just for the record, confirmed by my experience:
DO NOT FIT IN ZEBRALIGHT SC600
DO FIT IN SKYRAY KING MIMIC
DO FIT IN ULTRAFIRE SH98 (SIPIK 98 CLONE)
DO FIT IN TN31
Fit fine in the TM26 and should fit easily in the SRK considering my longer Panasonicās fit
How would these cells (Panasonic NCR18650B in general) handle 10A drain?
Very bad. They will get hot and well, you dont want hot LiIon cells.
So whats the point of having the protection as high as 11,5A?
Most cells can do 2C right? (??) So 6,8A should be ok, and pushing the limits a bit higher would probably not be that bad (despite decreasing battery life)? Or am I off now? (I know 1C is what is really recommended).
I know mountain electronics have protected PF (Orbtronic), but protection kicks in around 6,5A...
A couple of years ago the extra current was necessary due to incan bulbs (They require a high starting current).
Today you get slightly higher voltage at high current. You can usual expect about 0.1 volt drop over the protection, before it trips.
I.e. a 12A protection will have 0.1 volt drop at 12A or 0.05 volt drop at 6A
A 6A protection will have 0.1 volt drop at 6A, i.e. it will have 0.05 volt lower output voltage.
For most people this difference does not really matter, but there are some people around here that want everything they can get from the batteries.
