most power cells can be found at crash ships sites too. just take out the sentry drones or scav's guarding the place, i use the srv has it takes them out a lot quicker. The jump on the crashed ship and open up the maglock, grab the power cell (might be degraded) but it will work i think. Never try stealthie tactics either. But that just me I'm more of Rambo styleand use ship to kill everything with non seeker missiles. so you get a fine for murder and abet of notoriety but a few hours and it gone.
and most engineer weapons can now be found at starports.weapons shop i never engineered a suit or weapon yet!
Nah, only found degraded ones there.
I've switched to using the tactic of finding a faction i don't care about and agreeing to fix their disabled bases before riding off into the sunset.
