Has anyone here done a light saber battery mod? Just curious. I found some mini light sabers at amazon, Obi, Vader, Luke, and Yoda, but wasn't certain weather they are solid or hollow. They are about 4.3" in total length and I figured if they are hollow, you could add connectors for the 18650 LiO batt and drop in a 510/901 battery connector. The 18650's are only like 2.64" so it would give a couple inches for button and the connector and wires. I purchased a couple as they are only like $10 so I will know for myself here shortly, but just wanted to find out if anyone had already looked into this.
