Yea it was genuine. There was an official response from innokin posted the following day. I can't post links yet but if you Google "official response from innokin regarding itaste vv3.0" it should be the first result. This is what their representative, Innokin_Paul, said:
"George said that this question has been brought up quite a few times and we will make an official response here and also have the response posted on our new official website.
The iTaste VV3.0 Battery is a high rate discharge battery and not a normal 3.5V. On this battery the 680mAh is the battery capacity when maximum electric current is reached however when a smaller electric current is used then the battery capacity is extended and is 800mAh. The example they provided me with is, for example, when the voltage is 5V and if you use at 1.5 Ohm Clearomizer, it will use a larger electric current. When you use a 2.1 oHM Clearomizer (provided standard with the iTaste VV3.0) then the electric current is smaller and the battery capacity is 800mAh. The mold for for the battery is 800mAh but with the high drain the suppliers labelled the batteries as 680mAh. If you have any questions about this, or if I have misunderstood the explanation, please let me know and we will continue this thread with the Innokin engineers. Thank you."
The battery that was removed in the original post was labeled 680mah, but Innokin is saying that no they're actually 800mah. It's kinda sketchy, and so is their response. With batteries, mah is mah, it's a specific amount of charge the battery can hold and it doesn't vary because of what resistance is applied. What they said is like saying your glass has more water in it if you drink it slower.
