See the many 10.000mAh 1860 cells you can buy on Ebay and Aliexpress. No manufacturer can make them but the Chinese have them.....

A while ago I placed new 18500 cells in my chinese Canon battery. It was a so called high capacity battery of 2650mAh, the 2 cells inside were 1400mAh and serial connected! So it was actually a 1400mAh battery.
