TrustFire Black/Silver Batteries 18560 / 26650

I noticed these “new” TrustFire batteries on both DX and Manafont, and was wondering if anyone has any experiences with them yet…

The 26650 at Manafont appears to be legit, with the hologram sticker on the shrink wrap, as well as the hologram label. (More noticeable in the photos with calipers.)

The 18650 at DX also appears to be legit, with hologram labeling… although I don’t see a hologram sticker on the packaging, but they only show one side. Also new is retail packaging. (I wouldn’t guess a knock off would go to that much trouble.)

And capacity labels that sound realistic… Hm. Interesting.
I hope HKJ tests them :slight_smile:

Maybe they are trying to stay ahead of the cloners?

You might be on to something, maybe this is the 3000 re-wrapped, with proper capacity claims.

You will find a short test of the 26650 on a japanease page:

I like the new TF 18650 style. Seems and feels more legit….

But only tests will prove their performance. :slight_smile:

Hint Hint :smiley:

TF did Panasonic rewrap before, but the price isn't so great comparatively.

I think this one is probably a Sanyo 2600. If confirmed so, I found my new favourite.

8

Word. It’ll be my favorite as well. :heart_eyes:

I have put in a order for them, but do not expect any result on this side of xmas.

Thank you! :santa:

There's a 2-pack now, better pricing:

So itchy to try, but I already have 4x 2800mAh Samsungs incoming.

Then again, you know, I might need more batteries... for emergencies... right?

i saw in the DX november-order lottery, that someone had bought the 18650s. would be interesting to see a test of them :slight_smile:

14

That is a good news… Thanks HKJ…

Well I could finally receive my Trustfire 2600 cells. I just finished measuring one of them after cycling it once. I used Accucell6 to discharge it and this hobby charger lets only up to 1 Ampere discharge.
My charged and discharged one cell, and charged it fully with Intellicharger I4 V2. I discharged it at 1Amp rate and the result is 2572mAh at this rate, down to 2.8V. Well the cell voltage was stable, fell slightly to the end but still it was 3.32V at 2100 mAh point.

Now I discharge the second cell and it seems to hold up good too, has been at 3.64 V for minutes and at 740mAh discharge point. It is now 3.55V at 1060mAh point.

My first time with one cell was around 2500 at 500mA discharge. it seems to have improved on the second cycle, reaching its manufacturers claims.

I’ll report again if the second cell discharges too off this first cell.

Thanks kokopelli. It’s maintaining high voltage, sounding more and more like having Sanyo cell inside there.

Though right now, fasttech does have real protected sanyo for about the same price…

17

I don’t plan to take of the wrap to see but as FT offered many better deals maybe we should wait for the FT price for these.

Second cell finished it discharge cycle BTW.

1st cell : 2572mAh at 1 Amp
2nd cell : 2582mAh at 1 Amp

Not bad for two separate cells. Now we need someone to show their high current abilities.

Thanks for the testing.

I bought a pair of the “true” 2400 TF Protected Flames back in October. My testing has not produced good results. I’m running tests with graphs now, but at .2A capacity of one was around 2280mAh. At 1A it’s a sad story; 1622mAh.
Running a 1A test on the other one now… not looking good… I’ll post a graph when it finishes.
Edit: I just realized this thread was for the Black/Silver variety… Oops.
Edit2: Here’s the graph of 1A discharge on cell 2. 1632mAh…

Looks like a lot of internal resistance…

What kind of connection you have between your charger and the cell? If it’s cheap plastic cradle from DX, it has huge internal resistance by itself.
