This is high current rated 14500 LiIon cells. Can TrustFire be trusted?

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

[size=+3]Conclusion[/size]

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.

Unprotected cells with different capacity may exploded if used in series.
