Car battery energy cannon

This is an old idea i had laying around, and this is the 4th attempt which actually got done.
Inspiration was taking from fallout 3 tesla cannon, and fallout: New vegas elijahs jury rigged tesla cannon.
I just made a more realistic approach.
I used unreal engine´s default character as scale reference.
The textures do seem a bit low for the resolution which is 2k, but that is some unwrapping that can be optimized. Maybe ill fix it in the future.
Constructive crititism is welcome.

There is some minor issues, but i wont spoil them until someone notices.
