Does anyone know of a mod that just adds larger energy storage for IC2? Gregtech recently got voted out of my groups mod pack. I don't really miss all that much from it apart from the massive storage like the aesu and the lesu. The group said they wouldn't mind a mod that added larger energy storage if it didn't affect any other mods like gregtech does so that's what I'm on the hunt for. I haven't been able to track anything down through google so far so I though I'd ask a forum . Any help is greatly appreciated. Thanks in advance .
