Very good info on 18650 Batteries.

This was interesting to me, especially the 6th post with the graph.
Looking at the 2 amp rating [as an average of what we might draw] many brands come close to each other.
Note the brand names.


18650's help please?

Interesting. For a 2A draw, AW 2200 is a pretty lackluster performer.
The CalliesKustoms Panasonic 2250 has almost twice the run time.
But the AW 3100 and the Panny 3100 are neck and neck at 2A.
Looks like the "Spark"??? 2600 Is the bet performer of them all, on the basis of runtime.
I think there's a bit more too it than run time though.
Put them through 40 or 50 cycles and see how they stack up.
Also, we drain our batts differently than flashlights do, so I don't know if you can make head-to-head comparisons like that.

Anytime you see 2900/3100 it's a Panasonic cell, you have somehow ignored one of the best performers in this test, the TF3000 which has one on the best showings.

I wish they would list which Sanyo the Spark and the xtar uses (Sanyo makes a few 18650s).

why the difference between the redilast 3100 and the other panasonic 3100s?
