Callies Kustoms new 3100mAh 18650 batteries for sale now!

Hey everyone,

We finally have our  new 3100mAh 18650 batteries for sale! These cells are based on the Panasonic 3100 cell. After testing these batteries we have found them to be the best performing cells on the market. Their capacity is the best we have ever tested. Their 5A discharge rates are amazing. As of right now we have 100 protected and 100 unprotected batteries in stock. I don't think they will last long. EDIT..... we really want to get some people to try these out so we are dropping the price to $13.95-$14.95!  EDIT..... Shipping is a flat $6 in the USA, sorry no international sales just yet. You can buy them on our website at. These have a low profile button top to keep them short-er. 

Edit... We also have the new Panasonic IMR 2250mah battery. Not only are these the highest capacity IMR battery they are the first non China made IMR I am aware of.

Actually guys , that's a very nice price for a top of the range battery ...

Hopefully wont be too long before a review is posted !

I'm waiting for the first review. My few experiences with cells that say they are over 2600mAh, is that they aren't. Hope I'm wrong, but so far that has not been the case.

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...

I hope I am. What does "based on the Panasonic 3100 cell" mean? Is it a re-badged Panasonic or not?

If they are XXXXXfire and they claim north of 2600 you are right, but the Panasonic based AW 2900 I have are all over 2800 mAh @ 0.5A (discharging to 2.5v). Obviously I expect these should outpeform the 2900s.

What does  "based on the Panasonic 3100 cell" mean?"

 

This means Panasonic does not add protection circuits to batteries. They are sent to a third party assembler who adds the protection circuit, top terminal or tabs, they put a wraper over them and add your brand of sticker to them. In our case, my wife is a graphics designer and we had our own stickers made up rather than use theirs foil labels. So if you decide to cut one open yes you will find a Panasonic battery. 

I just did YET ANOTHER discharge test at 1A= 2928mAh @ 70f 2.5v cutoff If I was selling fakes I would not be sending these batteries to people who are known to post reviews and in fact encouraging them to do so.callies-kustoms-18650-3100mah

Be-seen, we are actually in the big city of Cornelius Oregon. Between Hillsboro and Forest Grove. My in-laws have a vacation house in Goldendale Washington. Thats where I wish I was right now rather than working Cry

Hi, folks.  I am very interested in this cell, and am contemplating purchasing the unprotected version, as I use quality chargers and lights with low-voltage cutoff.

 

A question:  my lights go to low at around 3.0 volts, and cut off at 2.8 volts.  How much of the battery's capacity will I be forgoing if I run the cell from 4.20 at the top end to 3.0 volts at the bottom?  Or, to state it the other way, how much capacity will I see from 4.20 volts to 3.0 volts?

Thanks!

 

Smile

The capacity of the 3100 panasonic cells from 4.2v to 3v at 1amp is around 2800-2850mah according to panasonic. Don has measured 2775 and 2735 to 3v on the first cycle of my version of these cells. The capacity can be increased at higher current draws and higher temperatures during measurement, I would also expect capacity to slightly increase after a couple of charge cycles. There is also of course extra capacity from 3v down to 2.5v.

 

Remember, the other high capacity li-ions by AW an Redilast (2900s) are also measured down to 2.5v so even if you don't see full capacity with these you will see the the same proportion of the rated capacity as with those too, so still more.

 

The numbers have been slightly edited upon re-examination of the Panasonic data-sheet, as it is a discharge curve so the numbers are an approximation by me.

As received voltage was 3.76v 

Came off the charger at 4.19v 

Discharged at 0.5A = 2730mA @ 3v  and 2900mA @ 2.5v   , This is the result for first charge + discharge ..

Currently charging for 2nd go around , but it takes nearly 6 hours to run a 0.5A discharge , and I expect it will take a while to charge as well . 

Still , an excellent result !  considering my Samsung 28A [ 2800 rated ] discharged 2488mA @ 3v cut off .

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

Arrived yesterday, thanks! No time for testing yet, but resting voltage is at 3.9 a tad high but no real problem. Anyone done a 10A discharge on these yet? I am very curious how they will hold up compared to AW IMR 18650 for an SST90 build. Not sure if my iCharger 106B+ will even handle that kind of load without an external resistor (and I haven't figured out how to do that yet either.)

More than I do!

 

I try very hard to be honest, but sometimes I don't have the equipment to do the best tests possible.

 

Beyond 1A discharge my tests aren't reliable - as in not one of my chargers can give reliable results past 1A. Can run a datalogging meter on current past that on the rare occasions I boot the only box running Windows around here. Last booted it in March.

 

But integration is not one of my skills. I last had to solve multi-variable differential equations in 1982. And have exactly no wish to remember how to do it 30 years later.

 

The numbers from my light tests are always to be found here.

I don't think I would try a 10A discharge test! Panasonic recommends 6.2A as max. The 106B+ is rated at 20w max discharge, something like 170w with a external resistor the setting should be under discharge+. I have found on mine it will go really quickly up to 4A then slow way down and sometimes take 10 minutes to get to 5A. I'm not sure if this is a battery or a charger thing? 

I was reading on a RC board that the 106B+ has some pretty small resistors so you may want to wait till you get an external resistor setup before you try any big discharge tests.

Yah, wish I had sprung for the 206B now. Hobby king shows up to 7A discharge current, but like you say, limited to 20W. Have to look more into using a 50W external resistor.

A 2C discharge rating seems rather conservative to me. If I had the equipment I would seriously consider a 3C test, but I guess not at this time Smile I thought I saw the original NCR18650 2900 drawing nearly 9 amps in an sst90 build.

Well, no time for even basic discharge tests again until at least Sunday. Boo. Real life.

I've already done a couple 5 Amp discharges of these (with good results). This afternoon I started a 0.6A discharge hoping that I could get around 3000 mAh (Panasonic states a minimum of 2950mAh). Well I got 3100mAh on the nose! Holy moly.

 

I'll be doing more tests and posting the results in my battery graph thread next week.

2C is generally considered the safe limit for the discharge of LiCo cells.

I took it down to 2.5v(+ or - .02v)  and AFAIK it didn't kick in.

EDIT: After looking at the graph, I can't be sure. It may have kicked in right at 2.5v.

We just ordered another shipment of batteries... We also ordered some new high drain 18650 Panasonic batteries. These should be some really good performers! 2250mAh and 10A max discharge rate. They are manufacture rated for multi cell use and have very long life! 

These cells where originally developed for power tools and medical equipment. Like all Panasonic batteries I would expect them to come in very close to their rated output. We should be getting them in within the next couple weeks hopefully sooner Smile

PS... If anyone out there wants to review these batteries let me know, you will have to be able to do high drain tests and post graphs. Thanks

"from everything i have read. worth the price of 4 TF flames? not to me."

Its like saying I could buy 4 Ford Escorts for the price of 1 BMW... Their really not in the same league. You will also note I am selling them for much less than the Redilast 3100's and less than the AW 2900. But thanks for the input!

and i agree with the escort vs bmw scenario. the difference is i can have one tf in my light and three back-ups in my pocket, but i cannot drive one escort and have three back-ups in the trunk. again, to each their own.

The Escort isn't a trustfire flame.  It's more like an ultrafire 3000.  It goes a while on a fillup, if you don't mind it taking a very long time to get there, and it failing in a month.  But you can buy 8 of them instead of 4 or 1.

I guess I never did come back to this thread. I posted some discharge tests in old4570s thread on CPF. Nothing too extensive, a 3.1A and a 5A test. Any data is useful, right?

 

Good luck on your sales, as always!
