26650 flames

Anyone know about the 26650 flames? I want a 26650 light and am not sure which batteries to get.

Looks like a very poor attempt at a TF label. Fake if you ask me

Fake Trustfire

That's an attempt at humour, right?

LOL. Probably.

Looks like the ones I got from DX. Haven't checked how far they go but I guess I will in the next car detailing session.

Kokopelli, let us know how good those are. I am also interested in these batteries but would like to see a review first.

I have an Accucell 6 hobby charger and maybe I can give the true charge it holds but the charger only discharges with 1A maximum. I also have King Kongs. Maybe a comparison between these two can be better.

Oh, sorry for the late reply. I could try these only this weekend. I used an Accucel 6 Hobby charger on NiMh discharge setting and down to 2.6V. I didn't have a proper holder for 26650 batteries so I used strong magnets to make contact.

Both cells at their first cycles, @1 Ampere discharge, King Kong yellow 26650 cells measured 4.300mAh and Trustfire Flame 26650 protected cells measured 4.380mAh. I couldn't test how far they would go at higher discharge rates but this test showed these two batteries could match well.

I plan to use 1x TR 26650 and 1x KK 26650 in series to have short circuit and partial low voltage protection in my Trustfire J12 5xXML light.

I wouldn't recommend mixing and matching different cells unless they have very, very similar performance characteristics, and with regard to that, you cannot match the cells by capacity alone. The voltage of one cell for instance, even though it matches the other cell for total capacity, may drop lower under load than the other cell. You then risk reverse charging of one cell by the other.

Broadly speaking, I wouldn't recommend mixing different brands of cells at all.

I still think they may have a similar base cell after all. But as you have said the behavior of different cells vary very much, but still, I don’t think these two cells will be much different at 3 amps. Need a better measurement, of course.

Please don't mix the different cells, as small differences in internal resistance and capacity can cause a dangerous condition.

It is best to wait for the post to deliver a matching set, IMO.

I have brought one of these just to test out and see if they can be used in series with TR-J12 with out modification unlike the king kongs, they are only 4000 mAh + not the claimed 5000 mAh, but they should be close to the king kongs with mAh.

When it gets here i can do some discharge test upto 7 amps down to 2.75 volt and some data logging on my computer and see how they go with the king kongs, but i have only brought one for now.

Looks like a flat top to me, but who knows

I think your right, ill try one and see how it goes.

hey Kokopelli does the positve button on the protected trustfire 26650 stick out past the side of the battery or is it like the king kongs ?

It sticks out just enough, Im testing a protected trustfire 26650 battery now Wink It seam's good to me sofar, will take a long time to data log and test but i will make a thread once im done.

Ive test a trustfire protected 26650 5000 mAh battery from 4.2 volt to 2.75 volt discharged at 3 amps it did 4313 mAh. Also they can be used in multi cell lights with out magnets
