add an o to the name and subtract a 0 from the capacity.
one i tested came to 317mah.and comments here lead me to believe that one is better than most.
i have seen sk68 style lights built with nice buck-boost drivers all the way to direct drive li ion only cheapies.
measure current at the tailcap as mentioned earlier.
I was just thinking about that yesterday while LMAOing!
I’d say “detach a 0”… ROFL!
Cheers :partying_face:
The cell could go into thermal runaway, venting violently, possibly catching fire.
Also, the greatest risk is when you go to recharge it after discharging.
With these shady cells, we have seen things such as the canister actually containing a small lipo inside instead of the li-ion roll that should be in there.

hey, thats fair. Whatever… but… .WAIT a minute… that wasnt my good 26650… my mistake…
PS - actually, i “misremembered”… ACTUALLY the “3.7 volts no load the next morning?” was actually one of my 4x “sh!tfire” 18650s i have? I dont actually expect those things to have any capacity… heck, if they give up 8 or 10 hours on “lo mode, 120ma” thats all i expect out of sh!tfire 18650 batteries, lol…

i just bought a “DeWorld” dual channel charger on clearance at RatShack a ways back… this was before i ever ordered from china before, and didnt ever yet use MTN before… so…
shrugs
dual channel charger made me happy, came with 2xAA-sized Lithium, so at least i had SOMEthing to run both my 68s i had acquired… one AA lith didnt work, but… on clearance i couldnt complain as the other was good…
clearance being clearance, i picked up 2x26650 “DeWorld” at the same time… price was right, and, others had bought them and said they were decent.
the sh!tfire batteries? i dont even remember where all 4 of them even CAME from… i think my first 2 came from a “yard sale”, they charged up, so, i toss them in the pile… the other 2? i got a cheap charger basically for free when i bought a cheap zoomie light, so, now i have 4 sh!tfire 18650 batteries…
i just use them for “wimpy lights”.
but, thanks for bringing it up, actually… coupe of guys did capacity tests on the 26650 radio shack “DeWorld” batteries, and said they were cool… i use them in any of my three 1504s from the group buy we had… they seem to run good in them.
since you made me think about it? i’ll have to run my 26650 cheapie zoomie on “lo mode” charged up, and then see what the no load voltage is like 8 or 10 hours later, lol… i bet its pretty good…
my basic plan, was that since people on HERE has said the “radio shack 26650s” on clearance tested good? the idea was my cheap china zoomie i sorta like? has a pretty low “lo mode”… i figured i could go all WEEKEND fishing or camping on one of my 26650’s, let alone having a second one charged up for the trip…
heck, THESE days? i now know if i ever want a “real battery” here in the USA? i just order a “kong” or whatever from MTN and i am good to go…
Hello! :)
Mmm, just saw this unusual CREE Q5 1200Lm Zoomable LED Flashlight Adjust Focus Torch Lamp Light 3Mode 14500 bla bla bla SK68 clone.
In the specs it is said it only works with 14500 li-ions. Heck, I may give it a try, though honestly, I don't really need it. It is only because I have a couple of unused TF Flame IMR14500s.
What is the size of the driver board on these? 17mm?
Cheers ^:)
Well, mainly looking for a decent cheap 3-mode driver host since I’m planning on swapping its stock emitter.
Cheers :partying_face:
Cheers 
P.S.: overpriced bullsheesh.
Just try it if you have the battery. I suspect about 1 hr on high.

Found that on an SK68's pill a friend just gifted me. Tailcap current looks to be close to 1'25A on a li-ion cell. Looks good to me. I may add an R330 over the R120, should boost the driving current to 1'7+A… 
Cheers ^:)
