I ordered some Trustfire 26650 batteries from DX, TrustFire 26650 Li-ion Batteries Rechargeable 3.7V "5000mAh" (Pair) - Free Shipping - DealExtreme
The price was $17.20 per pair.
They arrived at me yesterday and I did a test on them. These are protected cells and the top has extra large vent holes. I never seen it before. I only know the King Kong version and the Trustfires don't like it.
The batteries are put against the IMAX B6 charger. First I discharge it right out of the package. The remaining capacity is +/- 3000mAh. Not bad.
I charge the 26650 to the maximum with my DC linear PSU. Very handy for charging big batteries
Then I use the discharge mode with 1A discharge. The IMAX stops at 4016mAh. I set the discharged rate at 0.1A and with a further discharge I manage to squeeze another 280mAh out.
I don't know if this a a right sequenced but otherwise discharging it from full cell with 0.1A takes a very long time. And I am little impatient. :shhh:
A total of 4296mAh capacity. Not the same as the rated 5000mAh but in line with the other brand 4000mAh 26650 cells.
I also measured the internal resistance with a 3Ω resistor. Cell 1 has 119mΩ and cell 2 has 112mΩ.
I believe they are new cells and not fakes. The Trustfire 26650 looks legit to me. Thanks for reading this testing. :thanks:
