TrustFire is not the best brand around, how well do these high current cells work?

The curves do not match, but are in the same range, current handling looks acceptable for IMR cells (They are not that different from other brands).


The high current performance for this cell is about average, the cell matching is worse than average.

I have a couple of these, I use them in single cell lights and they seem to do fine. I now will never use them in series after seeing the mismatch between your examples.

Thanks again HKJ!
