RCM MonsterMike makes battery trays and sells them in his store. Carbon fiber is another alternative and yes it will hold up if you do it right. There are good and bad ways to produce items out of CF, and it can get a little bit tetious, and complicated if you have never done it before. We have seen guys in here who have manufactured some pretty good items right in their own garage, but it can be a costly gamble if you have no idea what your doing.
