"So if you plan on having your ship live longer than 9 turns in battle, regenerators will give you more hitpoints than the equivalent mass in shields."
As far as I know shield regeneration starts only to be effective when you suffered hits and already lost shield points and not before the ship is actually engaged in combat. Now for tactical combat you are right, I can withdraw my ship and wait until the shield regenerate. In strategic battle however, this does not happen and in my experience the ship will be destroyed within 3-4 turns because the enemy focuses its attact on 1-2 ships at a time. I ran quite a few combat simulation on auto/strategic and the ships with shield regeration did worse than if I used the same space for additional shields. In my estimation the shield regenerators would be interesting if they provided equal shield points/kT in 3-4 turns.
And for fighters even with shields a single unit will be destroyed by 2-3 point-defence canon hits. Here again the fire will concentrate on one unit of a group at a time.
