I ordered a Bestfire 18350 IMR from GearBest for my Astrolux S41 with hopeful, but low expectations. The battery label claims 1100mAh and 30A capacity. I can’t test batteries like HKJ and others, but after giving it a full charge I put it in the light and measured 6A at the tailcap with the S41 on turbo, only somewhat less than the 6.9A I measured using my Samsung 30Q. That was pretty impressive. A red Trustfire 14500 IMR measured around 4.5A. I don’t really want more than 6A going through this anyway (and it could be less or more since the tailcap wasn’t in place). I measured the discharge capacity on my Turnigy Accucel 6 which always measures about 20% less than better tests (stops at 3.0V), so if I correct for that, I think the true capacity of the cell is about 850 mAh at 1A discharge. For about $3 per cell, that seems pretty decent. The cell is essentially a flat top.

I posted basically this same review at GearBest and they gave me 10 points, but they didn’t actually publish it.

Sounds like a great cell, albeit with crazy mAh and A claims. I wonder what’s underneath the wrapper.

Do not trust any ” **fire” battery
They may fire yourself

I agree it looks like a good cell, prob near equal to the best available 18350s. Thanks for taking the chance on it. The price at that gearbest link says $1.81 for me!

I have had this cell in my Gearbest favorites forever but wasn’t sure about the quality. Many thanks for taking the risk and the feedback; just ordered two of them for my Solarforce (extended - 2x 18350) or a short 18350 I would have to build.

price came up as 2.85 first but after deleting/adding it back to the cart it resulted in 1.81 $US (and only 1.27 $US after points deducted).

Thank you.
