Surprisingly there are some cells up to 4000 mAh now, independently tested.

But I'd still be skeptical of anything I haven't tested myself. Far too many fakes on the market, and it's really easy to rewrap with a faked label.

That said, if the pack as a whole works well enough for /u/Harenraj56's purposes, then the true rating doesn't necessarily matter. Could still be a good idea to test for balancing purposes.
