Kumabear’s Keeppowers
edit; sorry, won’t be cost effective with ship to Israel.
Wallbuys replied with a very strange answer, but in the end they won’t reduce the price.
So I went ahead and ordered the SRK but now I’ll have to “gamble” on another source.
Still looking for suggestions…
aarggghh, szwholesale sell the 2pcs for 13$ + 6$ shipping. Their retail counterpart, www.qualitychinagoods.com, only has the older red Xtars.
Just noticed that EH doesn’t say it’s a Sanyo cell.
So it’s about 17$-20$ a pair on szwholesale.com or eBay.
Too ’xpensive… makes me kinda angry at Wallbuys.
Just checked Xtar’s Israeli retailer. http://xtar-il.com/?page_id=240
Is this a joke? 220 NIS = 60$ for one battery? Even for two it’s ridiculous.
baaahhh I hate buying in Israel. 
(btw, they sell the WK25 for 54$, WP2 for 76$, and WP6 for 95$. This IS a joke )
theres a member in here named stevebarnhart that sells those xtars for $13 shipped. I bought 4 from him at two seperate times.
super fast shipping but im not sure if he ships out of the country.
Really old thread but maybe you can contact Serena and get a better price?
Second post XTAR 18700 Li-Ions group-buy (Status in 2nd Post)
And… Wallbuys lowered the price to 12.54$ per battery.
Not as ridiculous as the Israeli Xtar retailer, but still too pricey. :~
Thanks, but I doubt they’ll give the time-limited promotion to one person.
And anyway the QCG site features the red Xtars. I don’t know if there is any real difference, but I want to match cells, so I’ll just grab some purple ones, eBay’s or SZWS’s, whichever the PayPal finger likes most.
I bet you can still buy them from that thread. I got all 8 of mine from there, just shoot them an email and see.
Mine are all purple.
I’ll give it a shot. 
I find both:
the red letter 2600mAh: Informasi Situs Toto Togel China Macau - TOTO MACAU
the purple letter 2600mAh: Informasi Situs Toto Togel China Macau - TOTO MACAU
Thanks, how did I misse that? It’s even cheaper than the red one. 
But the purple one doesn’t have a Sanyo cell inside?
Strange, I’ll contact them.
Thanks again!
QualityChinaGoods confirmed - their red label Xtar are Sanyo cell, the purple label Xtar are not Sanyo cell.
That’s actually more strange to me now - in sz-wholesale they say the purple ones are Sanyo. 
I emailed Xtar to verify.
Purple(and red) 18700 are Sanyo. Purple 18650 are not
Thanks, I didn’t know that.
I wish they were more clear on the issue.
Xtar customer service just made me totally confused.
The email exchange went something like that:
me: “Some sellers say Xtar 18700 2600 mAh RED label have a Sanyo cell inside, some say the PURPLE ones do, which are correct? Maybe both?”
Xtar: “For Xtar 18700 2600mAh,they only have red label and Sanyo cell inside. But maybe you are refer to our 18650, they both have red label and purple label, but not Sanyo cell.”
me: “But szwholesale.com have 18700 2600mAh purple label and they say ‘Sanyo inside’…”
Xtar: “I’m sorry that the describle of color in the last mail are wrong. I have corrected it as follows:
For Xtar 18700 2600mAh,they only have purple label and Sanyo cell inside. But maybe you are refer to our 18650, they both have blue label and purple label, but not Sanyo cell.”
me: “If the 18700 only have purple label, why is there a red label 18700 on your site?”
Xtar: “I’m sorry make you confused. I just mean that this colour is purple.”
me:
Lol.
Really confusing also they mention blue which are the 2400mAh ones…
The 18700 seem to be all purple also the one in the picture is a purple one.
And in these seem to be sanyos…anyone ripped one wrap down…?
I like the black color so I won’t going to de wrap one as I have only the blue shrink wrap which doesn’t look so cool.
In what picture?
I just guessed that the one in the picture is a purple one but looks like red…
But I don’t know it exactly, perhaps this isn’t a real picture just an animation…or so
I thought the xtar 18700 were always purple(like the wallbuys ones), isn’t that fact?
Never heard of Xtar cell manufacturer, as I’ve just seen by a glance, they are Sanyo cells, so just get Sanyo cells. Why pay somebody for rewrapping and writing an XTAR on it?
Makes no sense to me. You can get both unprotected and protected Sanyos from FT, I have the protected ones, made a review too. I like them, work fine. I don’t notice output brightness drop and if then it’s slightly and the battery is about to need a recharge and the light warns me soon.
Why?
because they were sold for 3.86$, so I bought 3 of them, too.
Also these are a bit smaller tan the FT Sanyos and have a nice black shrink.
I will charge mine up and then see if they have an overcharge protection, if not i will tear the wrap down to see if it is a 18650ZT…
