18650s $5 a pair?

Hmm, sounds like I may have missed some thread now? Or just forgetting something...

Anyway, I got two pairs from there. Both alike. First with higher capacity and way higher Amp output and the second not even on-par with best

Dino-Lottery TF 2400's...

edit, correction: got first ONE good pair, after that, TWO bad pairs.

I add here some links, some other people also have had not so good results:

Here's the cap for my first pair:

...and here for the second 2x pair:

Check a couple of posts below. Most astonishing thing was, they could not deliver more than 3 Amps even with a full charge and direct drive light (First pair was over 4A!!).

edit: and yes, the first pair was GREAT replacement for a bit too long Xtars. I was an idiot selling that pair away with STL-V2 :(

Are there any domestic sellers where I could get these and pay a bit more, but know they are genuine?

I am not anywhere near the level of being able to test them on my own.

Seems to me that Xtar had some problems with their batteries if I read correctly but I don't remember what was said.

I have bought quite a few Trustfire flames from BIC on ebay and I have to say they all seem good to me and perform well in my lights.

My results from BIC batteries, discharged at 1A:

Blue UF 18650 (2400mAh): 2 - 51 mAh

Blue TF 14500 (900mAh): 270 - 350 mAh

Blue TF 10440 (600mAh): 170 - 180mAh

Sad that even the tiny blue TF 10440, crappy that they were, beat the pulp out of the 18650 blue UF.

These are ALL from BIC. I honestly give you guy a heads up, skip these, a little extra will give you a LOT more for your money. Try to stay with Manafont for budget batteries, though not perfect, but still at least have a bit of quality control.

But in above post's you have said you have not tested them and you dont know witch ones are witch.... maybe not very good advice. In the past you have suggested cheaper lights then the tested lights, that have turned out to be fake or scam's and batteries that have tested poorly or the DD lottery game.

If people want tyred and tested flames there is one seller i stick to after test flames from many diffrent sellers.

Protected TrustFire 18650 3.7V 2400mAh Rechargeable Batteries - Flame (2pcs/set

The flame 3000;s are not worth getting as they tested the same for more or gave less then 100 mAh more

Most people will not know if a battery under performs in a light with a few one and off uses, run time test dont realy show the full picture either, there is people on here that do hours and hours of testing to show you the good batteries to spend your money on.

But it seams people will always buy the untested battery to save a few $ and then link them on here for houndereds of people to see and buy. Look at it this way a good battery will save you from a crap torch and a bad charger or worse.

A good cheap battery will cost you $10 to $15 a pair really good batteries will cost you $10 to $30 + each.

Good cheap batteries

Or if you want really good batteries

You can buy the same cell's cheaper but ive found the protection of the cheaper versions to have less (ic's) mosfets and the protection to be a bit hit and miss.

Make sure you add that to the bic recomedn thread !

I have brought a few sets of batteries from them that performed bad or very average, but was only give part refunds because they told me i still could use them.....

benckie: I think I will also give a try with Manafonts _2400mAh_ Flames, just to see... :)

Besides, I have only one (Yes, a frigging one Flame2400) left in drawer, others are gone.

Not to hijack, but there seems to be a dearth of 14500s. What are the best batteries? I need unprotected 14500s.

My 18650 flames from Manafont have bee OK thus far.

I have been very happy with these:

Capable of high current draw and safer chemistry.

Thanks BetweenRides.

I should have said 10440 batteries, but thanks for the info. It is always to get a user's assessment of such stuff. I have not seen any Trustfire Flames in 10440.

Best regards.

I'll be testing some soon.

Right now I just need 18650 unprotected (charger has inbuilt protect) for my cell charger (4P) to charge phone and tablet.

Folks here might be familiar with this cheap (but reliable, so far) charger.. from ebay with the 3 leds on the side.

Is Sanyo (pink/red ones) 2600mah the best bet? For 0.5mah discharge? Best bang/buck? Thanks!

How reliable is hke’s eBay side? I only ask because they have listed a trustfire 4 cell charger (tr-006?) And four 18650 cells for £31, I have not bought or tested these and am not recommending them, but if the seller is reputable they may be a good option?
Personally I trust BIG_F_D_D (torchy the battery boy) I’ve bought some lights from him that have been good, he has a return for full refund if unhappy policy (never had to test this, always been happy) and is based in Scotland. Good for us UK users, maybe not so good for you guys stateside. He tests and posts results of all his products and is a user himself.

What about these cells? They are cheap on ebay

Those look decent if the datasheet is to be believed. They have a fairly low capacity with only 2100 mah. Also depending on the light you may not be able to run them all the way down to 2.8 volts as they do. So I'd say go for it and as long as you are careful when charging and discharging they probably are safe. Good luck.

HiMax 2600's on Ebay for about $6 each.....

You mean this kind of box?

2600mAh Sanyo's are quite good for it, indeed, but I'd recommend using NCR18650A's instead due to lower minimum safe voltage, higher capacity & better safety apparently (due to NNP technology).

You can get 2900mAh ones for just $6.88/each or 3100mAh ones for $8.46/each (from FP)

What box is that? Link?

Here you go. I haven't tested 2.5A claim (it might be overrated by manufacturer, like those "1800 lm" XM-L lights), but it does 1A (which is enough for any phone) just fine without any voltage drop.
