I'm sure I saw the test results on the net, I'm looking, I seem to remember they actually tested at 2475 mah, I think.
Check out Wake and Vape, the LG HG2 are very good, I use them. They are rated 3000 mah and test at 2875. http://www.wakeandvape.com/batteries/
We have tested the 2900mAh and they're very similar to the HG2, testing at about 20A and 2850-2900mAh. Haven't gotten any of the 3000mAh yet or seen test results myself since it's so new. If Efest past experience is any indication they're probably a decent 15-20A cell but the HG2 is likely the better buy.
