I have recently ordered a skyray king and have two xtar 2600mah 1700 batteries which i was using in a tn11,ordered two more from a different seller.all 4 showed 3.81volts out of the packet,but when charged using a xtar wp2-11 the two original cells (two charges from new) show 4.22volts after a rest period where as the newer cells one charge show 4.21volts,would these b ok to use in the skyray king .any info would b gratefully appreciated .
Yes, a difference that small wouldn’t make any practical effect.
Yes, that is a miniscule difference. You will be perfectly fine.
@The other members of BLF, it should be fine that the cells aren't completely identical as they are in parallel.
flippin heck that was quick thanks for info…
Since they are in paralell, the SRK will run on a single solitary 18650……. if you should ever have to !
so as long as just use the 4.21 pair ,or the 4.22v pair in the tn 11 it will b ok .thanks once again…all 4 in skyray
All 4 in the TM11 is also OK, they are in parallel there, too.
NightCrawl, I guess he means ThruNite TN11, not Nitecore TM11. 
But thats a single cell light?
yeah should have been clearer thrunite tn 11 with extension 2x18650 lol
That makes sense, although I only heard of an extension for two 18500.. you never stop learning. :P
i bought it as new but second hand ,with two extensions for use with 2x 18650s,i couldnt use cr123s as the seller did not supply the anti rattle sleeve 4xcr123s stacked (i think i would have been asking for trouble)
