This is a standard 18650 and I know I need the extension cap, but in the second link it says that they added another layer of insulation making the battery thicker. First link is the actual battery's I want to get and the second link shows the thicker layer and the details that make it different witch brings up the question. Will it work? The positive buttons are also bigger in diameter so will that work?
