There is an enhancement for the power armor torso that allows you to go invisible while stealthing.

So one of the things that drive me nuts in this game, is the timed fusion cores, they only last about 20 minutes(or less if sprinting) a mod that made them last forever, or atleast a very long time, would be so awesome. :P It sucks having to get out of your power armor in the middle of combat, and go around behind it to replace the fusion core.
