Looks like mekanism is the culprit in this one, but I dont know what happened.

It's not, this is an IC2 error (I know you don't have it installed, long story).

Install the latest IC2 Experimental API. You don't need the mod itself.

I purposley avoided installing IC2, welp xD Thaks

Just the API, you don't need to install IC2 Exp itself.

Done, but now I get this error(It whont load.):
