For tripple cell, it would be even lower per cell. For this, standard manufacturer's way of measuring via 1/10C discharge (300 mA for 3Ah battery) is absolutely OK for us.

Panasonic probably wouldn't lie, but you have no guarantee that the cells have been made by them. The ones you can find locally are probably Chinese fakes with "Panasonic" printed on them, especially if they're cheap. Genuine 3.1Ah 18650 are quite expensive; I've had a look, and I can't find them for less than 12 euro each shipped from European sellers.
Yea, I was talking about price tag 9-12 euro, locally. It's still cheap, compared to cost of dual-scud, or dual-polarcell, or any other 2 flat batteries, used to create 3000 mAh dual-mod one.

As for 3,8Ah, I also haven't confirmed it, but from initial info, it was also Panasonic (successor of the 3100 model). Maybe it was hoax, after all.

Still, 6Ah battery from two 18650's, bundled *inside* device (with total thickness little more than N900 with mugen cover) is neat for me
