Arent Senybor also Sanyo based? Edit: actually it seems they are coy about this info but removing the wrapper has shown Panasonic apperance.
This guy is a seller but I have no reason to not trust his results:
How about these.. http://www.pandawill.com/2pcs-xtar-18700-2600mah-37v-rechargeable-battery-p54212.html Mine arrived in 4 days. Great value for these xtars.
I do not know what are they based, I only know they are made be a Chinese company in Shenzhen.I know that in UK there's a lot of buzz with Torchies cells. Well that is primarily because of all those 1A comparisons he did. He says 1C discharge and then the discharge is done with 1A, Then at 2C the discharge says 1A also. If you look at the graphs there's no voltage sag...... Actually the sag is lower on the 5.6A discharge, which is not possible.
I haven't bought high quality 18650s for a while. Are these HI-MAX batteries still a good value?

Hmm, I have some more Senybors now and really should get round to doing some more tests but in my tests they outperformed the @&£)fire cells. I will get the internal impedance tester on them also.
Aren't these fake? Some weeks ago found these and there were some doubts in connection with the company.
What about those 3100mah from Intl-Outdoor? Are they good?
If you might consider unprotected, I've been looking at these for a while, Sanyo 18650 2600mAh from Intl Outdoor, at $5.85 a piece. Free shipping if bought 3pcs above.
Its brother (2100mAh) has been tested to get 1800mAh, around 85% of claimed. Since it's Sanyo cell, I believe that result will be consistent, and for a 2600mAh cell, good chance you will get a good 2200-2300 mAh from these. Still a great value for the price.
No, they are the real deal. They have a US and China warehouse. After reading the bad reviews, I decided to risk and purchase them. So far I've had good experiences with Pandawill.
I recently had a DX Trustfire Flame go bad on me. Not in a bad way, it just wouldn't charge up anymore. I'd probably had it for a couple of years, but not real heavy use. So I bought some more XTAR 2600's from the longstanding group buy. I think those are very good batteries for a little more than Trustfires. Still a lot less than AW's and equivalents.
I have 4 TF 3000 soon here, wait a while before ordering. Quality may vary, going to test them…
Xtars with groupbuy price are the safest bet.
I can recommend the TF Flames from Manafont. I've bought about 100 of them in the past 3 months and I only had one that was DOA.
I think you're safest with the XTAR 2600 at $13.50/pair from Serena or I guess even that Pandawill site if you're feeling lucky. That's all I've been buying lately, for myself and for friends.
I have had good luck with HiMax 2600's in the past but they seem to have gotten very expensive.
I have over 50 Trustfire flames from DX some over over a year old all of them still work. The ones I have tested all had decent capacity.

massive discharge rate, low resistance, not going to explode
imo, they're the best value, hands down
They might not be the cheapest but I just ran some testing on these in a light that draws high amps and they truly are outstanding! Definitely more capacity than the AW IMR's and as long as your application is below 10A then you should be good.
I also used them as a pair in the EYE30 runtime testing and they yielded just slightly less than the AW 2600's:

(look at chart under: RUNTIME (2 cells) )
Are those protected? Seems the webpage doesn't say.

Those are great cells.
I acquired an identical one from Callie's, and it allows for more current in my Direct Drive SST90 than my AW IMRs by over a quarter Amp. (~280mA)
I will slowly but surely be replacing all of my IMR 18650s with these.
A very good cell at a fair price is the Sanyo-based Solarforce 2400 protected 18650. The wrap is a bit brittle, however.
no but I think callie's sells them re-wrapped w/ protection. They are safer chemistry cathode, despite saying li-ion on the side, so for my purposes, the protection isn't relevant (I don't drain my cells to where protection trips....on purpose anyway).
