AWT cells and charger data (and other cell comparisons)

This thread is meant to log any tests and comparisons I will make with the AWT products I have received. Feel free to suggest something or point out if I am doing something wrong or inconsistent.

These AWT products were received free of charge for the purpose of testing. There was no agreement made to do a public test(s) or review(s), but the generosity from AWT deserves at least an honest comparison and tests to be posted publicly.

Here is their Alibaba page, but it is full of a bunch of other products thats not theirs

26650:

AWT IMR 26650 (#2) - 3800 - 4417 - 26 - Brand new
Trustfire Flame 26650 (#1) - 5000 - 4492 - 35 - Protection circuit. Probably 25 to 50 cycles?
Trustfire Flame 26650 (#2) - 5000 - 4725 - 30 - Protection circuit. Probably 25 to 50 cycles?





Internal resistance consistency test:
For this test I will put one specific cell into each slot five times. I will leave it in the slot until it displays the internal resistance, pull the cell and wait about 5 seconds and repeat.

This first test was my very old and very abused Trustfire Flame 18650s:
Right slot: 126, 126, 126, 124, 125
Left slot: 124, 124, 121, 121, 121

This next test I used a brand new AWT IMR 18650 2500mah 35a cell:
Right slot: 18, 18, 19, 20, 18
Left slot: 15, 15, 17, 17, 17

As seen, the difference in results are about the same between the AWT and the TFF cells. The difference from left slot to right is also about the same in both tests. So it is possible to have about a 5mR difference between slots in each test. I am not sure how big of a deal that is, and I am also not sure if doing each test within 5 seconds was skewing the results. Maybe they were getting slightly charged or discharged, and not having time to rest back to its normal state.








Will be adding some data below, such as:
- Checking voltage of cells fresh off each of the chargers
- Maybe some tailcap readings from one of my XML2 lights to see if they push harder than my current cells


Anything else you guys would like to know, or see done to test the chargers or cells, let me know. I will do the best I can

Thanks for the effort Pulsar. Do they sell direct?

The charger on the right looks similar to the Basen charger. Is that the one that did internal resistance testing? I don't see how with only one button. The charger on the left looks like the LiitoKala Lii-260 tested by HKJ which had internal resistance testing.

Updated the final round of 26650 tests.

They will sell direct, and they have an Alibaba page that I will add a link to in a bit. But they have the typical high shipping charges because they only want to ship with DHL or FedEx.

Thats how I ended up getting all of this. Got a quote for the Lii-1000 charger, 2x 18350s and 2x 18500s. They wanted crazy shipping because HK Post wont ship LiIon. So I got a quote for just a charger, they wanted $14 for the charger and $24 for shipping. Said I will have to pass. They came back with they will send me a charger to try if I just paid the $24 shipping. I was a bit hesitant, but I bit.

When the package came, there was 16 cells and two chargers. So I figured the least I can do is put the Lii-1000 to the test and jot down the results of all my cells, including the new AWT, and post it publicly for comparison.


Eventually I will get around to more tests besides the cells capacity and internal resistance. But that will wait until I am done with this

Started on my 18650s. Will do all my old cells first, and then the new AWT for comparison.

BTW, I think my charger is consistently reading 15-17% high on capacity. These numbers are not absolute and should only be used to compare to my other test results. Numbers seem to be consistent though

Updated 18650s with another pair of results

18650:

Sanyo (#1) - 1500 - 1553 - 25 - Pack pull.
Sanyo (#2) - 1500 - 1596 - 25 - Pack pull.
Sanyo (#9) - 1500 - 1518 - 26 - Pack pull.
Sanyo (#10) - 1500 - 1596 - 21 - Pack pull.

8

Updated another pair of 18650 to the list

Sanyo (#3) - 1500 - 1546 - 28 - Pack pull.
Sanyo (#4) - 1500 - 1604 - 24 - Pack pull.

Updated the OP with a link to AWTs Alibaba page:

http://aweitebattery.en.alibaba.com/

10

Added another 18490 to the list that got left out. Will probably throw the AWT 16340s on the charger to run a discharge next.

Efest IMR 18490 v2 (#2) - 1100 - 1176 - 28 - About a dozen or so cycles

11

Plenty of good info here.
Really appreciate the time you put in generating all the data Pulsar.

12

No problem. Most of my cells have had pretty light use right now, so should be good for comparison. I did have 6 or 8 laptop pulls that had a rough life, but I tossed all those once I got the Sanyo B&D pack. I am expecting to find one of the Sanyos that has a lower capacity and higher internal resistance. Accidentally ran it down to a stupidly low voltage...

Got my trusty ol Trustfire Flame 18650s on right now.... lets say the internal resistance does not look very good

To be fair, they were my first and only 18650s for a long time and they are probably about 3 years old.

I saw a thread from microbluebear looking for people to test some cells. I was late to the party, but I offered to run them through the discharge test to add to my comparison and then do a giveaway with the cells... have not heard back. Got more cells than I need as is, will probably give some away in the near future

13

Updated OP with two more 18650 test results:

Trustfire Flame (#1) - 2500 - 2536 - 117 - Old. Used and abused
Trustfire Flame (#2) - 2500 - 2593 - 84 - Old. Used and abused

14

Updated the OP with the AWT IMR 16340 results. Unfortunately, I have nothing to compare them to though...

16340:

AWT IMR 16340 (#1) - 550 - 623 - 58 - Brand new
AWT IMR 16340 (#2) - 550 - 640 - 68 - Brand new

15

Updated 18650 catagory. One last pack pull to discharge, then on to the AWT 18650s, and then I think I am done with what I have


Sanyo UR18650W2 (#5) - 1500 - 1545 - 24 - New B&D tool pack pulls.
Sanyo UR18650W2 (#6) - 1500 - 1597 - 25 - New B&D tool pack pulls.
Sanyo UR18650W2 (#7) - 1500 - 1562 - 24 - New B&D tool pack pulls.
Sanyo UR18650W2 (#8) - 1500 - xxxx - xx - Cell at 0.37v. Tossed.



Edit: I do have a set of flat top 18350s to test too


Edit: Sanyo cell #7 test complete

16

Got the AWT 18650 results up.

AWT IMR 18650 30a (#1) - 2000 - 2185 - 18 - Brand new
AWT IMR 18650 30a (#2) - 2000 - 2219 - 15 - Brand new

AWT IMR 18650 35a (#2) - 2500 - 2641 - 20 - Brand new

One last set of cells to go for now I think

17

Got the AWT IMR 18350 flat top results in. I think that is all the cells I have for now...

Next up will be some tail cap currents on some various lights I have, and maybe on some e cigs to see how they compare at heavy loads
