26650 Batteries

Hi there,

very interesting information on the last pages, thank you. I didn’t have much time for my FandyFire HD201 since April, in the meantime the 26650 cells got quite popular I think.

I have two Sony LiMn 26650 (made by Molicell?), which delivered easily more than 6 amps in the HD2010 (Maximum= seems to be direct drive). Minimum voltage is 2,5v, maximum 4,2v. I think, in earlier days, max. voltage used to be 4,1v with nominal voltage of 3,6v, but now you can charge them with the normal lipo programm.

Capacity is supposed to be around 2500mah, I got a bit more capacity (started charging at3,0v):

I have different RC Model chargers, for these batteries I use the small charger:

this one works very precisely, but some of the cheap chargeres like IMAX aren’t very precise, so be careful

this is the battery:

Sure, the capacity isn’t that massive. But the maximum discharge is 10c (!!), so you could get up to 25 amps, which is a lot. So far no problem at all with them, will buy some more probably. They are safe and powerful. Some shops in Germany sell them, like lipopower.de, an other guy sells them on ebay.

AFAIK these type of batteries are used for Sony Laptops (the smaller 18650), and the bigger 26650 have been around a while, used for power tools, and lately for electric bicycles. There aren’t so many different manufacturer for lithium batteries, most of them in china. Molicell is an Canadian company, but of course manufactures in China.

Some years ago, the “Konion” batteries have been popular amongst RC hobby people, but are hard to get nowadays. I would like to get one of the 26700 cells. Here’s a comparison of these batteries (in German):

Quite interesting are these ones with 4000mah:

it says “WNICR26650C1”

thanks again for all the interesting information, for me, 26650 are the future. More amps, higher capacity, and like the sony/emoli, pretty safe.
The only problems I had with batteries so far were NIMH Cells, which burned and exploded. so I think, they all can be dangerous to some extent. I would never buy myself some (fake?) batterys from an unknown shop. They probably get damaged due to the high power LED we use nowadays, ’cos they can’t stand the high current draw.

Picked up an Ultrafire blue protected 26650 3.7V labled as 6000mah. Has been thru 6-8 cycles so far. Maybe I’m doing something wrong, but the capicity seems WAY lower than advertised.

Here’s dicharged from full at 1.0A. 1677?!!?

I’m in the market for a 26650 cell with better numbers. Might as well run an 18650 with a spacer…

King Kongs unprotected or TF 5000 protected from Manafont or CNQG can't be beat.

Yea, wouldn’t really expect anything more from the UF, they are all total crap.

So I made it through the first 5 pages, and yeah my head hurts. You guys are maniacs! :wink:

Lots of information, especially the precautions about batteries exploding.

Which leads me to a question regarding the safer LiFePO4 style of battery.

Are there any of them that are in the 3.7v rating?

I poked around and all I see are the 3.2v variety.

Welcome to BLF! All lifepo4 batteries are 3.2 volts. The voltage of a battery is defined by how the battery is made.

Thanks scaru!

So then is the next safest route to use protected batteries?

It seems that those ensure the battery doesn’t get pushed too far in either direction.

Pretty sure my flashlights are all regulated as well.

Yep, protected batteries are the way to go. Make sure you also have a DMM to measure voltage.

Yep, i’ve got a decent one that even does capacitance.

Now I just have to go back through the 3,139 links I saved from this thread.

Shouldn’t take more than a month I’d imagine…

Welcome to BLF, LED A. Stray! Now don't exaggerate; there's only 3,122 links in this thread.

You might also try some of the IMR Unprotected, which are supposed to be a safer chemistry. Powerizer 4000mAh from Batteryspace seems to be the best price on these.

Well sure, but I double clicked a bunch of them… :bigsmile:

I just finished the order now. I went with a couple of the small single 18650 lights from DX.

And i’m also going to give the A8 a try.

For the 18650’s I went with the Panasonic ncr’s from HKE on ebay. I’ve bought from him previously for my big Fandyfire UV-S5.

I also got the 26650 Trustfire 5,000’s from him, because his shipping is so fast.

And I took heed of people who have gotten a dead battery in a batch and ordered extra batteries while I was at it.

I want to thank all the hobbyists in this thread that helped put all the info on this interesting battery in one thread.

A8 is a great light. Fancy Flashlights has a killer combo deal which includes the A8, TF 5000 cell and charger. HKE sells the A8 as a standalone. Good luck with all your new toys.

Have a pleasant time here at this friendly forum, LED A. Stray!

It probably has a 18650 inside it (laptop salvaged as well)

Hi guys, new to this flashlight world. I’ve been reading many threads on here and this forum has been very helfpful.
I was wondering if anyone has had any experience with the SoShine 26650 4200mAh protected Li-ion batteries, I found them on tmart for $8.99 (and has anyone had any experience with tmart.com?). Here’s the link to them:
http://www.tmart.com/1-Pcs-SoShine-26650-4200mAh-37V42V-Protective-Liion-Rechargeable-Battery-with-Board-Black_p161839.html

i picked up a trustfire 26650 from tmart today - i am interested to see if it performs as good as the mf battery… i already noticed that tmarts length and weight of the battery is slightly different (tmart length 2mm shorter and slightly lighter than mf)

i have a 26650 king kong to compare to when it gets here (i do not have a hobby charger)

:bigsmile:
Now; no longer have a 26650 :bigsmile: :bigsmile:
Some day some one will make better 26650’s.
not going to wait around me at 71 ain’t got not time to waste |(

Hello, dial and welcome to BLF. Have not seen any information on Soshine cells, but at least their capacity claims are within reason. Tested protected TrustFire 5000mAh are available for just a few more dollars from several sources listed in the OP (Though they are more like 42-4400 mAh actual capacity). I have used TMart for several flashlight purchases and had good experience, but I have not made any battery purchases, nor will I until I see some of their cells tested. If you do try these, by all means let us know what you think.

Welcome to the party, dial!

KD has 6000mAh 26650 cells. I’m curious what is the real capacity and chemistry
