Some mod questions.
 

Is there a way I can stop torpedo's from being exploded at 300+ m Depth? When I shoot a torpedo it blows up right when it leaves the tube if im around 300 meters or so. What file(s) do I need to edit/change to fix this?

Also, I want to find the file(s) I need to edit to extend/shorten the battery life.

Thanks in advance!
