Yes, finding the keyword is not the problem though. What I think I need to do is mimic the "isPowerarmorBattery" keyword or make a new one with the exact same function. Making a new keyword and how they work is what I have not managed to figure out. Copying and just renaming "isPowerarmorBattery" to something like "isGatlingLaserBattery" should hopefully be enough as long as I learn how. Just using the existing keyword makes the game treat it as a Fusion Core that can get loaded into a PAframe as OP says which also makes it get used automatically when the PAframe runs dry. Having my EC packs for the Gatling Laser get used (and for some reason converted to Fusion Cores) when they get drawn from my inventory for the PAframe is what I would like to fix.
