I have a Ego style battery that I am guessing is a 650mah its made by White Rhino measures about 3 inches which is how long a 650mah is supposed to be from searching the web this I copied off a website about the Kanger EVOD 650mah it says its length is 3in. 75mm the size of the 900mah from what I found searching is 85mm 3.3inch which is the size of the Kanger EVOD I got today but i ordered the 650mah i dont even see where goodejuice.com sells the 900mah..... i will try to post pics later
