Do these mods work on a truePVE server? I set it to auto turret everything, with and without a battery and I can't seem to get it to target anything or see a place to put a battery like mentioned above. Am I doing something wrong?

If the turret isn't targeting things, that's due to another plugin. You can try unloading some plugins to find out which one. There may be config options in that plugin which allow you to adjust the behavior.
