Hey guys I'm new here, and I'm going to be doing a luxeon converison on my Luke 05 MR. My problem is that I borrowed the saber to my brother a while back and the idiot lost the end that holds that battery case inside the hilt. I'll be fabricating a new end to fit on but I'm not sure what kind of batter pack I can use. I also know I'll need a speaker. And links or ideas would help a lot. Thanks!
