Picked up an Ultrafire blue protected 26650 3.7V labled as 6000mah. Has been thru 6-8 cycles so far. Maybe I’m doing something wrong, but the capicity seems WAY lower than advertised.
Here’s dicharged from full at 1.0A. 1677?!!?
I’m in the market for a 26650 cell with better numbers. Might as well run an 18650 with a spacer…
Welcome to BLF, LED A. Stray! Now don't exaggerate; there's only 3,122 links in this thread.
You might also try some of the IMR Unprotected, which are supposed to be a safer chemistry. Powerizer 4000mAh from Batteryspace seems to be the best price on these.
A8 is a great light. Fancy Flashlights has a killer combo deal which includes the A8, TF 5000 cell and charger. HKE sells the A8 as a standalone. Good luck with all your new toys.
i picked up a trustfire 26650 from tmart today - i am interested to see if it performs as good as the mf battery… i already noticed that tmarts length and weight of the battery is slightly different (tmart length 2mm shorter and slightly lighter than mf)
i have a 26650 king kong to compare to when it gets here (i do not have a hobby charger)
:bigsmile:
Now; no longer have a 26650 :bigsmile: :bigsmile:
Some day some one will make better 26650’s.
not going to wait around me at 71 ain’t got not time to waste |(
Hello, dial and welcome to BLF. Have not seen any information on Soshine cells, but at least their capacity claims are within reason. Tested protected TrustFire 5000mAh are available for just a few more dollars from several sources listed in the OP (Though they are more like 42-4400 mAh actual capacity). I have used TMart for several flashlight purchases and had good experience, but I have not made any battery purchases, nor will I until I see some of their cells tested. If you do try these, by all means let us know what you think.
I have one "Trustfire PCB 5000mAh" 26650 cell from T-mart, when I bought the HD2010 I had no 26650 at all and thought why not buy all together.
Bad choice.
The HD2010 is perfect, don't get me wrong, the only problem is that the 26650 cell I received is NOT an original Trustfire.
First of all, it's NOT protected. It says on label about pcb being green blah blah, but reality is that there is NO pcb at all! (that explains also why the Tmart spec are 2mm shorter than other Trustfire 26650)
Second, the wrapper is very badly shrinked on, I can make less wrinkles when I do my own RC packs heating the shrinkwrap with the phon!
Capacity is still unknown, as I've not had time to perform a real capacity test with the RC charger (being unknown cells, I have to arrange things to make the test outdoor, as a safe precaution). Anyway, I used it on the HD2010, checked voltage and ampere consumption, and sure they don't lack in punch, as I recorded a steady 3,4A barely touching the cell bottom with the prongs, without pressing the spring, and quickly increasing over 4A if I pressed the spring, so did not wanted to push the luck further.
Still I use it on the HD2010, being a single cell light I feel confident that when I avoid any overdischarge there's no real risk.
But I switch to KK INR 26650 if I have to use the HD2010 for long periods.
So the final consideration is: BE WARNED, the 26650 T-mart sells under the Trustfire 5000mAh wrap are fake and not protected.
