I have some really serious question about it.
First of all,if the cloak discover range is at like 4500 meter for battle ships,and as we all know the longest range weapon heavy motar is at 5000m range,it would be really useless for battleships,attacking from behind or any good position at that long range would not give u any advantage since IT IS WAY TOO FAR,even if u use heavy motar it takes 5sec for the shot to reach the target,it give too much respond time and not mentioning cloak is often used for some close range combat because it's can tacticaly shorten the range to your target,if u can't, why not just carrying a normal fit? And the cloak also takes the contermeasure solt,what's the point of using it? Fooling the npcs?
Secondly,since u are changing the cloak,how about the cloak disruptors? These detection range make the disruptor looks like a clown,u can see someone coming by looking at the player list and listening to the cloak sound effect,if they want to do anything to u they will have to reveal themselves sooner or later,why u need a cloak disruptor since it is already hard to build.
The last point,u have mention human technology, what about nomad cloaks? I agree with it if nomads have some advantage, but how would u do the balance?
The detection range is a good point to change the clock, but by now the number and mechanic are not yet wisely consider. Here's some of my rough idea:your cloak have a short charge up time and reduced cloak time, but take the same amount of battery every time u charge, the absolute detection range should be greatly reduced(these need tests),but when u get close enough to someone(should avoid the player u team up with), your cloak time runs out faster, force u to make quick decide to attack or run or just simply fly by to make an investigate(if u need a explain for it, it takes more energy to mask the ship undiscovered when u getting close so the energy u charge runs faster), the charge up should be interruptable by some means not only the cruise disruptor, since not every ship could mount it but every ship with contermeasure solt could mount a cloak by sacrificing cargo space.
