Hi Have you ever tested the above cell?

No!

Okay!

Ooops, was wondering if the question was to me or HKJ...

Totally agree - these posted test results have been invaluable for reference. Specially like this as a comparative reference:

This write up on hobby chargeres is also a great, classic source of info: http://lygte-info.dk/info/HobbyChargers%20UK.html

Plus this page on chargers (and batteries): http://www.lygte-info.dk/info/indexBatteriesAndChargers%20UK.html

Thanks HKJ !

How about the Samsung INR18650-29E 2900mAh.
Is it same as this -20R version, except with higher capacity? I’m tempted to buy one of those for flashlight use..

Hhhmm, think the lower the letter, the lower the max amps rating is, but not sure if that's a definite rule. I got Samsung INR 20R, 20Q, and 15M's -- in that order I'm thinking is lowest resistance to highest from my testing in builds.

The 29E is rated for a discharge of 3C max. That's about 10A. The 20R will do 30A easily.

I assume the HD2010 and Sky Ray King will pull currents over 5 amps only when the supplied voltage really starts to sag after an extended run time?

Fascinating this :~

Lights like SRK have the cells in paralell, and will pull currents like 1.5 amps per cell.

Hi.
Will I see any significant improvement in output if I use these batteries for my XintD X3 and Supbeam K40-L2? For lights having cells in series, do you also divide the current pulled by the number of cells?

Thanks a lot for your another excellent test review as always. I never knew there is INR 18650 & it’s from Samsung.
It’s interesting this cell’s charging time (around 131min) is a bit faster than Efest IMR 18650 (2000mAh) V1 red (around 140min).
