Hi,
are you sure that these are NCR18650B? How did you find out? I saw them on a different site as NCR18650GA. I wanted these because they're supposed to be high drain - unlike the NCR18560B. Also the label says 10A.
Thanks.

The protection circuits and button tops are added by the rewrapper in this case, but they definitely are ncr18650b cells. The sanyo cells you referenced test at 3500mAh actual. The FT test is consistent with them being ncr18650b cells.

Woah, mama!

i fail to understand why anyone would be interested in these batteries in the first place. you can get better cells for less money.

Maybe certain people in certain countries don't have easy access to good batteries?

I was just looking for protected batteries with decent capacity that also offer higher constant current (for modded flashlight). I do know that there are cheaper unprotected cells and that a protection circuit is a limiting factor.

Without the protection, these are my new favourite batteries. I mean the GAs, not specifically these rewraps.

So these are better than Samsung 25R's despite the fact they cost twice as much? Can you elaborate why please?

How does the fact they are protected affect their usage please? Can they be used in mechanical mods?

Grant me the serenity to accept the things I cannot change; courage to change the things I can; and wisdom to know the difference. Living one day at a time; enjoying one moment at a time.
