Tesla Weapons

[Altissimus]

My ship has 50GW generated energy and <10GW required energy.  When I fire all my weapons for a sustained shot (say, 10 seconds), the top energy bar is still not all the way over to the right hand side.

 

My understanding is that this means I should be able to fire indefinitely.  I.e. generated energy is still greater than required energy even with all weapons firing.

 

However, in prolonged space battles, I've noticed that my energy bar progresses towards the Right when I use my teslas, and does not fully reset when the weapons are rested.

 

Why is this?

 

[Ohm is Futile]

Most weapons that use energy use increasingly more if you fire for long periods without rest. Rest period depends on how crazy you went with your burst. Bit of a strange mechanic, but it's essentially a balancing factor like overheat in my opinion.
