My interpretation is "Yes, they need to perform EA while nested. They decide during EA, when everyone else does. Power comes from either batteries or engines, same as usual. Note that they can't tap batts until engine power is exhausted, so if you want to empty the batts by running the panels off battery power, you'll need to run the engines at a level lower than is needed to run the panels."Does this mean, then, that satellite ships need to perform EA all the time, even when nested? And another thing is that when does a Satellite ship decide how much power its engines are producing? (5V3b) Where does the power come from to run the panels while nested?
A follow up question for Mike: Can Sat Ships arm or hold multi-turn weapons while in the hangar bay, like TR beams or DisDevs (for Pythons)? It's not on the list of explicitly allowed actions. If not, then it implies that a sat ship will not have TRs ready to fire until the second turn after launch. E.g. launch turn X, pre-arm X+1, arm and fire X+2. I believe that they can do this in SFB.
