Nifty. Any way to tell which cells use the Sanyo UR18650FM?

22

In the reviews of the batteries I do specify what cell they uses (If I know it).

Check Keeppower 2600mAh.

Thanks. Found out the Xtar 2600 supposedly uses the Sanyo as well, but people report different (worse) results than the bare OEM battery, with speculation the difference could be the protection circuit adding resistance.

24

They also could have older batch cells inside.

25

Protection does add resistance, I cannot tell you exactly how much, but for a good protection it is probably below 0.05 ohm. That is below 0.25 volt at 5A.

No 2600mAh cells from Panasonic?
