Trustfire is often not that good quality, what about these cells?

The cells do not track perfectly, but that is often case with 18350 cells, especially at high current.

Conclusion

The cells can deliver a lot of current, they do look fairly average in performance for a high current cell.
As usual the difference in performance means it is best to use one at a time.

Thanks again for another great test on a *fire battery. I linked this test in my BLF A6 18350 tube thread for those looking for options. Hope you don’t mind. I don’t buy batteries or chargers without reading your reviews any more.

This one seems like a good option…

Thanks for the review HKJ.
This cell does looks like AW IMR18350, plain red wrapper with black letterings, with the same capacity, but at a fraction of the price :bigsmile:

I was interested how these would perform, nice to see the graphs.

Thanks

The top button looks different to me.
Compare this to the OP pic:

I know they are different, and my post shouldn’t be taken seriously, hence why I put a :bigsmile: smiley after my post.
I do have the AW, which is rated to 12A continously, but I’m not sure about this cell

I think the aw looks like the awt Big Smile . thanks for the review hkj, can you tell me, are there many manufacturers of cells this size? Maybe trustfire have no choice but to sell a reasonable cell, that’s all there is!

I don’t how many he has reviewed, but there are plenty, including: Keeppower (Normal/IMR), Efest (Normal/Purple), Soshine, Nitecore, Bestfire, Ultrafire, Trustfire and Fandyfire. The ‘fire’ variants may be hit or miss, from what I hear Keeppower and Efest are the most popular, especially their high amp versions.

It is not a widely used cell size, this means there will not be many manufacturers, but I do not know how many.

To be fair to trustfire, my understanding is that their cells aren’t too bad, but the copies of them are a nightmare, giving them a bad rap!

i just received my 2-pack from gearbest and charged them up. i made a quick test on my BLF A6, and a samsung 30Q pulled ~4.75A on turbo, while the TF IMR managed ~4A (i don’t have any shorty tube yet, so i have some trouble holding the battery and measuring at the same time :bigsmile: )

so i guess i got genuine batteries from gearbest that should perform well!

edit: tested them on my opus BT C-3100 @1A now, and got 780 mAh on both. they also have a steep knee at 3.40 V, just like the ones in this test.
