Ultrafire 18350, unprotected

I´m talking about these: http://www.dealextreme.com/p/ultrafire-18350-3-7v-1200mah-batteries-pair-50485

Might also be available elsewhere.

18350, "1200"mah, unprotected.

If there´s already a thread (which I somehow missed) please close this.

I have a couple of these which I use in my L2m.

The case is, I would like to insert a higher performance dropin but I have no idea how these perform.

If you have any idea of real capacity, reliability or how much is reasonable to take amps from these, I would be very grateful.

I have never heard of 18350s they look pretty decent. I will have to try some in my 501A host. You should have no problem pushing 2-3 amps to an XML with these batteries I do it all the time with 16340s. I noticed Lighthound has AW IMR 18350s those would be perfect for a high amp draw application.

AW 18350 IMR in L2m with some XM-L dropin would be quite juicy...

I believe Manafonts 3-Mode 4,2V XM-L would be the choice?

Well, if my Ultrafires can put some 2-3A out, that will suit my needs quite nicely.

I have a half a dozen of the Manafont drop ins they can't be beat for the money. I make my own drop ins for fun, but it cost me the same just for the parts as a complete Manafont drop in.

It sure isn’t too shabby. :slight_smile:

But maybe you might want to consider saving a few bucks and getting these IMR 18350s over AWs.

Here's my take on them.

I wish I could offer advice on the Ultrafire's but I don't have them. Although I can guess they're not 1200 mAh.

Thanks mitro.

IMR´s, cheaper than AW´s with free shipping. I´m a bit interested even though I don´t need the maximum output in L2m. Use it at work, need ~5-20sec bursts to check the production line, wide beam is advantage, needed throw 6 meters. Short bursts but many of them in a day. And hey, modes :)

Surely 18350 are below 1200mah but I would happy if they are even 20% bigger in capacity compared to regular 16340 (AW or generic).

I ordered the IMR 18350, 14500 and 18500s yesterday. The 14500s will be for Xeno E03 which means then it will gun it at about 2.4A. Super pocket rocket capable of running for 3 mins cooly somemore in warm white CT. The 18500s for the Sky Ray 3xT6 in 180mm length pocket rocket format capable of gunning in high for unlimited period as long as the ambient temp is cool (some measured over 2000 OTF lumens). Money mouth

And yes, the 18350s are for my L2M with XM-L drop in. (need to wrap tightly in foil)

I've got some of the orange ultrafire 18350. On my tests at 1A, they give around 800mah

Thanks for info, hazna.

800mah sounds promosing enough. I have Imax B6, I just realized it has discharge capability also so I could test my own specific batteries with it. Damn, they are at work...

These Ultrafires put out same amount of Ampers (roughly), than my Trustfire "Flame" 2400mah does on Kaidomain XM-L dropin. Some 2+Amps

I got 2 of these the other day. They both give about 650-700mA when discharged at 1A on my Accucel-6 and deliver about 2.5 amps on my XM-L light, about the same as my AW and unprotected green UltraFire 18650.

I have only cycled them both 1 time (discharge fresh from envelope - charge - discharge - charge) so they might give more with one or two more cycles.

Volk did you get the Ultrafire 18350 or one of the IMRs?

E1320:

Sorry for not being clear, I bought the orange UltraFire from DX.

I´m at work now so I have to take these numbers out of memory but I think the cells went down to about 3.6V when I applied the 1A load. So if you need cells in this size I think it would be best to go for some good IMR cells since they should hold up a lot better under load and by doing so probably deliver more amp hours.

Ultrafire's flashlight Cost-effective

am i way off base, or is imr a safer technology vs. lion that does not need a pcb? thanks.

now i'm confused...

You got it right IMRs are safer they do not have a protection circuit and you can jam em at max amps in and out no fear of boom, but they don't hold as much total energy "mah".

should be awesome for a smaller light with one of your xm-l drop ins. i'm also looking forward to maybe a 3.5 amp one, as well as custom stuff with your new program. as soon as funds are available, of course.
