Increasing visual acuity:

I'd like to request the battery box (all energy storage units really) texture set be updated to make it a bit more obvious where the output is? After being wired up, the output "dot" terminal is covered. If the box is surrounded by power cables, you can't find the terminal since the cables poking inward also cover it's sides as well.

Maybe a larger "bullseye" of a terminal cap that exceeds the diameter of the power cable? A 4x4 image rather than the 2x2 currently installed. Possibly some extra doodads on the front texture corners? (I know there's not many pixels to work with)

Changing the one of the textures, side or front, to outward facing themed motifs? Possibly a neutral pattern? All sides feature an inward faced motif that blend seamlessly together; aesthetically pleasing but frustrating in use with a wrench spinning the object around accidently.
