I'm using the orange ultrafire xsl 18350 1200mah 3.7v.
4 of them cycled, used them for almost 2 years now. so far so good but of course the batt life has since dropped compared to initial 6mths of use.
I liked them.
edit: been using them on both mech and step up/down voltage mods. no issue. had 6 but dumped 2.
built a 0.7ohm atty and i put in 1 fresh batt. whole mech mod turned hot so i dumped it.
Then i realise fresh batt can hold a charge of 4.2v =.= was noob so that kinda slipped my mind.
Batt turned hot but no venting and no oozing of chemicals was observed. Also no physical expansion of battery was visible as well if any.
2nd batt dumped becuz i dropped them pretty hard. like it kinda flew out of my hand, got to a good height b4 landing on concrete ground.
Dumped in case something was wrong.

how about flat top 18350? They seem to be not readily available anywhere I look.
Try fasttech. I have a bunch of 18350s from them and a couple of efests. Performs the same if you ask me.
Disclaimer, I don't run sub ohms. I normally run 1.6-1.8. If you do or are planning to I'll say try to get the IMRs.
yea was looking there as well as it was dirt cheap.
they only have ultrafire, trustfire (protected) and icr though.
don't think any are flat heads.
was looking at ultrafire as the capacity was higher than other 18350s.

I wouldn't recommend other brands other than aw imrs. The rest to me seem pretty dangerous.
To add on to the discussion, I feel that if the batteries are used within their parameters (ie no sub ohm vaping) they are a manageable risk. I don't really get the sub ohm idea. Sounds too much of a risk to enjoy a warmer vape.
I have my Vamo and MVP if I want to go mega wattage.

Having used Ultrafire and Trustfire 18650's for several years on other products I have found that you have to be careful. There are many knockoffs out there that purchase the exact same 'label' sleeves as the Ultrafire company and just shrink wrap them onto cheap knockoffs.
Many that I have found over the years that were at a good price claimed mAh's as high as 3,000 but tested out at 1,800-2,400 mAh's.
And I sure would not trust them in a juice hungry device.

Still looking for flat top 18350. fstoplights dun have them. Anyone can recommend a local place to get them? Shipping options are limited and I think alot of places dun ship them. Thank you.
