If you look at the picture closely, the 160mAh battery has two ridges on each side of the black part of the battery, where as the new V911 battery has just one ridge down the center.
However, the 300mAh battery has one ridge down the center of the black part, very similar to that of the new V911 battery.
So from my observation, it appears that the 300mAh battery may fit the new V911, but if one wanted to use that 160mAh battery, they would have to file down those ridges on the sides.
