Drag racing at itās finest! I wouldnāt have thought that would happen, cool test. See? This is why as a noob Iām having others mod some lights for me, I know good and well Iād fry things! Thanks for that, sorry she went but, well, wish youād have had video rolling! 
Yeah, learning myself too. I had the Led mounted on copper, and it pulled 7Amps of a couple of other different 18650ās, so i just couldnāt resist trying the new INRās that arrived that day
You gotta love these experiments. Nice.
That seems to be what I need.
To sad that enerdan donāt sell these as single cell. Perhaps I ask about that.
that the samsung you used? : http://www.ebay.com/itm/Original-Samsung-INR18650-20R-SDI-3-6V-2000mAh-Li-ion-Rechargeable-Battery-/261134798326?pt=US_Rechargeable_Batteries&hash=item3cccd8cdf6
Yes, they are the ones
the price is good.
Its the 1600mah AWās <15A discharge. And tested above 15A
Samsungs are great cell, i wish you could buy them new rather then pulling them
or buying pulled cells off Fleebayā¦Iāll stick with the AWāsā¦
The samsungs that Enerdan sells are new, not pulled cells.
Good to knowā¦Thanks
@nofearek9: I linked them in post #5.
@DarkSide: See post #5. I got the ones from China, they are genuine and not used. And Enerdan wont sell used cells. ;)
Do u have a graph with 5c discharge?
This is an impressive little cellā¦. It just doesnāt sag too much like you expect it to from a 18650 cell.
Do u have more graphs available ? Just wondering.
I have got one last week, indeed a nice currentdeliverer.
And it reaches the rated capacity! The most cells are at least 100mAh overrated.
I've got almost anything from 1A to 20A but most is not really interesting. Up to 10A you are better off with the Panasonic NCR18650PD. And from 10A up the Samsung 20R is the way to go. I can think of 2 cells that might be better but those are exclusively used in battery packs.
Can u post 2c for comparison purposes. Iām not familiar with the Panasonicās but Iām pretty sure at 2c they will sag more than these.
Sorry to keep asking for graphs.
These are not IMR but INR for low discharge the 3.4ah is good but the 2.9 is better and sags less
2C is a wide range. ;)
2C is 5.8A for Panasonic -PD, 3.2A for AW IMR 1600mAh and 4A for Samsung -20R.
So here are 5A and 7.5A.
At 5A, there is no real surprise. Up to 5A I'd say stick with the Sanyo -FM if you already have them. If you need more runtime, the -PD.
At 7.5A the Sanyo -FM would be beyond specs and gets hot. We dont want that, so no graph for that cell.
The three cells have a very similar discharge curve with the -PD having a lot more capacity. In this graph it was only discharged to about 2.9V. Discharging it to 2.5V would give about 800mAh more capacity.
/edit:
Ignore kreisler, he is just trolling. :P Protected cells are for girls btw.!
Why do you recommend the Sanyo FM? Because it is the better choice at 3Aā¦?
In the 5A and 7.5A diagrams the PD is the bestā¦?
