The two batteries in the pack has different capacity, but both handle up to 7A fairly well.

Conclusion
Very small capacity differences are usual acceptable, but here the difference more than 10%, not very impressive.
If both cells had performed as the best cell I would have called it good high current performance, but with this difference the final result is rather bad.
Notes and links
Unprotected cells with different capacity may exploded if used in series.

Mmm, too bad the consistency isn't up to par. I recently tested my pair in this regard via in series discharging, and I accidentally brought them down a hair low (below 4.5V). Disconnected the shebang and finally measured the final resting voltage: 2.59 and 2.57V, so guess my pair was more or less well matched.

Cell binning comes in handy for battery pack assembly.

The human mind, and its programming, is at the forefront of a particular battle of The Light vs evil dark forces. Nearly every human being on this beautiful planet “Earth” has some sort of negative mind programming in its mind. And you better take care of your mind programming, or someone else will in this wicked world.
