AWT IMR18650 2600mAh (Yellow) 2015


Official specifications:

  • Size : 18.20mm x 65.05mm
  • NominalVoltage: 3.70V
  • Nominal Capacity: 2600mAh
  • Charging Metod: CC/CV 4.20V
  • Discharge Voltage: 2.50V (Average Cut Off)
  • Charging Current CC: 1250mA
  • Rapid Charging Current: 4000mA
  • Continuous Discharge Current: 35A
  • Max. Short Peak Discharge CC: 40A
  • Weight: 60gr.max
  • Colour: Yellow , Black
  • Version: Flat Top
  • Protection : No




This is a very high current 18650 battery with fairly good capacity.











There is fairly good tracking between the two cells and capacity is nearly constant up to 20A.















Conclusion

This is a high performance high current battery, it has fairly high capacity and can deliver a lot of current.

A VTC5,that’s a first.I see this years 2600mAh cells have a scratch and check patch under the AWT label while last years 2600mAh cells(25Rs) did not.Useful to check what sellers are supplying.Thanks for the test.

Agree i think they are VTC5’s but at higher amps they seem worse :~ or maybe they are old stock and have degraded a bit since HKJ tested a VTC5.

Anyway i look forward to your Sony VTC5**A testing HKJ :wink: they seem like the strongest cells out there now. For the first 30 seconds at least then the medium drain 3000mha cells like the 30Q hold the current higher in DD flashlights at turbo for longer.

And thanks for the test HKJ as always :slight_smile:

Ιt is the same cell with AWT 2500.
Samsung 25R.

5

Why do you think so, the discharge curves doesn’t match the green 25R, cyan 25R or the AWT 2500.

On the cells i have checked in the comperator the VTC5 comes closest.

6

Probably not noticed .
If you notice the discharges of 25R Cyan than the AWT 2500, they will see that is the same as trace.
Where has a bend , has the other .
Where is the top one , is the other .
If you notice you will see that the pattern of discharge , has exactly the same format.
In AWT 2600 you will see the same trace discharge , but with greater voltage drop .
This means that the item can be Samsung 25R, but is seconds and the result is a lower yield.
That has lower performance as Volts, but the same image as discharge , means that something is wrong with the battery.

So better to buy someone the 2500 .

If you noticed a trace can be hidden behind the other.
So this means that the battery is the same .
It should of course be hidden just about be the case.
As is the case we are talking about my friend

Yes i agree that the AWT 2500 is a Samsung 25R cyan.

BUT i see absolutely nothing that indicate that the AWT 2600mha 40A could be a 25R cyan, not a single discharge curve match at all & even all the dimensions is off like the size where the VTC5 is much closer + including the weight.

Remember that Keeppower has launched a VTC5 based cell recently so we know the rewrapers can get them freely now.

My bet is still that they are VTC5’s.

The truth is that there is a big difference in picture of discharge .
Another discharge has the 25R C. and the other 25R G., but as I wrote as an image discharge , the test performance of HKJ seem to have the same changes , while the discharge of VTC5 has many differences .
Do not look at only the difference in conserved Volts, because we have differences even in two identical batteries.
These two batteries But despite their differences , the footprint has the same image .
The weight can be changed depending on the equipment that everybody has . Not all devices the same components ……

The picture I see my friend is that it is a battery of R series of the Samsung.

If you notice more thoroughly discharges , you will see that best suit the discharges of 25R.
It looks like the discharge of VTC5, but in the course of discharge , we see differences and discharge lines not fit perfectly as an image .

This of course is my opinion not recant your own opinion , my friend .

It would be interesting if HKJ could start to add the temp of the cells in the discharge curves like Mooch does in his reviews, that extra point of reference could help figure out these kind of questions easier.

10

Very good idea.
It would show what battery last longer in rough use .
Personally , of course , no longer I look at the 2500-2600mAh, but it would be good to know .

11

Agree i will probably not buy 2500-2600mha cells anymore since the 3000mha 30Q & HG2 came out, but :wink: i think i will pick up one Sony VTC5A just for that maximum lumens & kcd output test when i have finished a new mod :slight_smile: + charge it to 4.25v just to see how the light looks when pushed to the absolute limit.

But who knows maybe Samsung have a 3000mha 30R in the works for high drain applications, i would be surprised if they didn’t fingers crossed :slight_smile:

12

I expect this battery from the moment I saw the 30Q ……
Given the advent of VTC6, the game will have multiplayer and of course this is good for us.

13

It would be, but I need two spare bench multimeters with network connection to do it and I do not have that at the current time.

14

Ok, is there something we could do to make such a things happen then :wink:

One thing i have been thinking about is, couldn’t you HKJ as a member who does an enormous amount of testing that benefit the community, open a patreon account for donations for example :slight_smile:

I am sure many members in all the various cell using communities would be happy to chip in.

15

I am thinking about updating my test stations and may add temperature at that point.

16

Sounds good :slight_smile:

I look forward to your future cell reviews with temperature information added to the discharge curves, to even further understand the characteristics of the various cells you are reviewing.
