Why do electric engines kick in when you submerge?
I may be missing something obvious here but why do the electric motors automatically kick in when you submerge? I assumed these motors were of importance only when maneouvering amidst enemy ships to maintain silence.
Should they be kicking in when I submerge during non-combat navigation? Is there a way (and a reason) to prevent the electric motors from propelling the ship when submerged?
What is the general thinking to managing battery charge levels during patrols?
