From Callie's Kustoms :


18650 Unprotected Battery

2250mAh

Unprotected

10A Max Discharge

Max Charge/Max discharge voltage 4.2/3v

Panasonic uses "PSS Technology" in this battery. A solid solution technology that allows the high capacity of a

standard Lithium-Ion battery and the safety of an IMR battery. This is truly a revolutionary battery!









For testing I have the Callie's Kustoms 18650 High discharge battery , the first thing I did was to test capacity by discharging from 4.2v to 3v @ 0.5A in my Hobby charger , I did this twice , and the results are 2168mAh for the first run and 2162mAh for the second run , and those results are very close and consistent , a good sign .

The next test was to test for discharge capability [ Amps ] , and I used 3 flashlights for this , my best XR-E R2 , my MTE SSC P7 [ long time test light ] and my XM-L T6 3 mode [ from Manafont ] , as the T6 is a serious battery vampire , and when you take a peak at the result graph you will see why .

TFF = Trustfire Flame or second battery from left , and TFG = Trustfire Grey third from the left and CK = Callie's Kustoms .

From the left cell 4 = Samsung 26C and cell 5 = Samsung 28A , from the left Cell 1 = Sanyo 2600 and the 3rd from the right = IMR and the black cell next to the IMR is the AW2600 .




Wow , check out the Callie's Kustoms [ CK ] , 3.9A in the XM-L . That is simply fantastic , and it goes without saying , it has simply wiped the floor with the other batteries when it comes to power delivery [ Max Amps ] . Callie's Kustoms has delivered again , a 18650 that performs so well and gives folks an option to other IMR . If you have to have the best , the highest possible power delivery , decent capacity , you need to visit Callie's Kustoms and check out this battery , it has impressed the heck out of me .

Is that the BIO IMR? Curious that it's worse than the standard Sanyo 2600.

These new panasonics do look good though.

Looks really good. Thanks for the detailed review Old! Frontpage'd and Sticky'd.

Original AW IMR , still performs about the same as when I got it ...

Did 3.1A in my MTE when I got it , still does 3.1A ... Same with the AW2600 ... Cant fault them for that ..

Thanks for the review! I'm glad you confirmed some of my results. I thought I needed a new multi-meter after testing some of my lights!

I just wanted to make this clear the new Callies Kustoms 2250 Battery is an IMR Battery. I had stated it was was a standard lithium battery. Some of the Panasonic sales literature was very vague.

Later press releases have confirmed it is in fact a "Nickel Manganese-based cathode"

It's just surprising that it's worse than the sanyo. I mean, what's the point if that's the case?

Another typical high quality "Old" review. Thanks for having such a great battery addiction and sharing your experiences of so many of those fun little cylinders. I hope I will live to see affordable carbon nanotube battery technology and 6000+ mAh IMR 18650's.

In our typical flashlight applications? Safety. That’s about it. IMRs are for higher discharge rates that regular LiCo cells are not rated for.

The Sanyo 2600 is an incredible cell and is still preferred by many people over the newer 2900/3100 Panasonics. They hold their voltage much higher than one of the high capacity Panasonics for 90% of their discharge. Now THESE Panasonics are much more like the Sanyo, only they have the added benefit of safety AND the ability to go beyond 2C.

Callie's High Discharge and other @ 3A (to 3v):

This post cleared about all questions I had with the performance differences and pro´s/cons with these batts. Thanks.

+1, Great job Old4570 !!!

I would like to live to see a zillion mAh "batacitor," as proposed by the late author Philip Jose Farmer.....part battery, part capacitor, it charges up almost instantly and can dish out power at a trickle, or all-at-once.

11

Great review, very interesting!

12

Just like the 3100's some people assume the extra capacity comes at the price of safety. Please understand I do not consider ANY battery "safe"

So I made a quick little video to see what really happens when they are shorted out.

You sir, have big brass ones. LOL

But have you tried charging it back up and using it? :p

14

Now thats something Id like to see other battery suppliers try

15

"You sir, have big brass ones. LOL

But have you tried charging it back up and using it? "

LOL sorry I tried, the battery is Toast! its now reading .46v I tried 2 chargers. Both said connection break. I even tried the nimh setting to get it back up to chargeable condition. No luck but we can rest assured it lead a valiant life in the name of science

It is precisely coz of this characteristic that i'd love to gun them in DD triple XM-Ls for the Sanyo 2600. At $5 a piece, can't go wrong. The XTAR 2600 have very aggressive PCB protection but i suppose the discharge curve is similar. I can't get Rev Jim's Panny stuff, so these will do nicely. :D

17

intresting thread but at $29.41 AUD each shipped to oz puts me out

18

I saw you post on CPF , and yeah , upsetting the status quo !

There will always be someone .... But whats important , is the results .. And getting the info out there ..

19

you dont mean me

if so its funny how some peole on cpf thing its ok the parrallel charger batteries when the cells are discharging and charging them selfs from 2 to 6 amps + when connecting in parrallel and they think they are all corect and it will not harm or increase the internal resistance of the batteries over time, they make out like people who series balance charge are crazy,

20

I have less respect for CPFs "experts" than ever. I'm still an idiot when it comes to the whole thing, but that reads like a total backtrack. "Well no lithium cell is entirely safe..." Yeah... you wouldn't hear that if the cell said AW on the side.
