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.

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

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

Or if you want really good batteries

Redilast

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.

Pfft... hahaha... I have got everyone beat. 4pcs Blue UF 18650 from BuyInCoins, $3.20/pair, tested 51, 2, 3, and 18 mAh! Yes that was no mistake, TWO friggin mAh! 

Granted I got most of my money back and 5% discount card, but bottom line is, don't buy these cheap batteries, especially from BIC! Well, I don't mean boycott BIC altogether, their price, shipping and CS is great, just skip their lame batteries.

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...  Smile

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.

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.

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.

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.....

Rats, finally sold my 2010 509hp Mustang...now I can buy more lights!

Sold the red one too! Now guess what I drive, doing my penance for 500 hp commuters...

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)

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.

Ive seen them and was interested if they would give at lest 2 amps ?

but brought the protected battery holders instead, they are protected but will only fit unprotected cells like the NCR18650A,s

1 x 1S4P

http://www.ebay.com/itm/1-x-1S4P-3-7V-18650-Holder-Case-Battery-w-Li-ion-PCM-Protection-Circuit-Module-/150817618580?pt=LH_DefaultDomain_0&hash=item231d6e3a94

1 x 4S1P

http://www.ebay.com/itm/1-x-4S1P-14-8V-18650-Holder-Case-Battery-w-Li-ion-PCM-Protection-Circuit-Module-/180883464154?pt=LH_DefaultDomain_0&hash=item2a1d7e9fda

You can get them in many different combinations, 500 mAh is good for a basic mobile (cell phone) 1 amp for smart phones like the iphone 4 and 2 amps for ipads.

But with those you still have to use some kind of 3.7V -> 5V boost converter.

That's the one, thanks man. Will check out those Pansonics, FP = FocalPrice? Can be hit and miss with them, I think DE is also stock those now too

Yep, FP = FocalPrice. That's where I got mine and they seem to do very well (tested them individually in hobby charger, got similar results to Intl-Outdoors protected 3100mAh battery).

4.2 volt is close enough for me.

I was not sure if he needed 5 volt or not, not sure on how the pack is rigged, bit hard to give advice, i just seen 4P that could be 4s1p 14.8v or 1s4P 3.7 volt or 2s2p 8.4 volt as one pack miscounted as a 4P, but it looks like he has the voltage and the protection sorted.

Just about any 18650 can give 0.5 amps in series 0.5 amps each or in parrallel 0.5 divided over how many cells your using or a 2s2p will give 8.4v but will double the run time over a normal 2p but will look like a 4p due to having 4 cells.

But if your charging ipads or iphones and want a couple of charges, i suggest gettign good 3100 mAh cells but since you only need 0.5 amp i assume your not so its all good 

Since this thread went off coarse i thought ill help what i linked is more for testing or being used as a power supply what the batteries is charged at and what combination you brought is what voltage you will get.

I'm sure the batteries have already been order so it does not matter any more.

2100mAh at 0,95A is 2h run time. For 2,75$ good dealTongue Out But question is, if are these batteries realy new, or they are used.

Enyone already tried these LIR 18650?

Yes but no, really as a 1s2p 0.5 amp over two pany 3100 mAh's in parallel is bugger all, but like i said what i linked was more for testing and custom battery packs even charging with a hobby charger, i did not say it was for charging phones did i ?

Now since we are talking about charging phones, i use my car stereo in the family wagon to listen to music and charge our iphones at the same time plus the option of a cigarette lighter socket if tow phones has to be charge at once, good for camping but in our 4X4 i have to use the cigarette lighter socket's or a portable DVD player as the stereo is no iphone compatible its just an oldie as it gets full of sand, mud, dust and water.

At home i normally use 1 of 4 apple chargers we have, or my wifes clock radio iphone dock, or our surround sound system, or xbox or TV or my PC or my wifes laptop, or our blue ray player in the bed room or my daughters DVD player or the portable DVD player.

If I'm out side with mates or in the shed working on cars or what not i use my hobby chargers power supply with a couple of cigarette lighter sockets to charge iphones or ipads cause i normally leave the screen constantly on so i can skip songs and do stuff as i don't like shake to shuffle and i might be out there all day.

Now if i run out of options around the house of in our two cars and i have used all my 20 options to charge an apple product i do not stress i use one of these

MiMi - USB Rechargeable 2000mAh External Battery w/ Stand Feature for iPhone/iPod (Black)

MiMi - USB Rechargeable 2000mAh External Battery w/ Stand Feature for iPhone/iPod (White)

You can buy then to match the colour of your phones isn't that sweet.

Now iphone 4,s will charge from a 0.5 amp device. they like 1 amp as they are a bit hungry, but Ive noticed on some items that only give up to 0.5 amp like 10 inch note pads or net books, old laptops they time out while charging ipads they really need at lest 1 amp but are the most happy on 2 amps half.

Out of the 30 some thing usb ports in my house or cars half will charge at 1 amp and above and the ones i have made personally will do 8 amps each or up to 23 amps over 4 out lets if needed from 12/24 or 240 volt. So charging a phone is the least of my worries i prefer battery packs that are protected so i can test and blow stuff up that is not connected to some expensive electrical item hence my above links.

Hey thanks man,

Actually I already have quite a few Flames (from DX - apparently not so good anymore) & Himax, haven't ordered any more batteries yet (need more money, haha).

Benckie, I'm no expert (far from it) but I think that unit can only discharge at normal usb speeds, 500m

Thanks

Haven't seen any, this 4x 18650 is very compact, same height as iphone and not too much longer, very portable, also 2x version available see ebay.

I also have this http://www.intl-outdoor.com/ml102-usb-charger-for-18650-26650-battery-p-...

No, but it'd make no sense to use 26650's in such a box - a 4-pack of 3100mAh 18650's will have same capacity as 3-pack of 4000mAh 26650's while being lighter & smaller (in volume and height)

Thanks, I've been looking at that unit and searching around for reviews, but I don't know if it'll work for my particular application (solar power box) since I see a part where it says "no trickle charge". I think I'll buy one either way to fiddle with it and I could still use it by hooking it to another device either way.

Main reason for choosing the 26650 battery is because I can get 4 (4sevens brands) 26650 batteries for around $28 Money Mouth and I've been unable to find 18650 batteries at anywhere near that price range

Care to share your source? They cost $15 each from 4Sevens site.
