Batteries
I've got a question regarding batteries; The only ones I can see are the crude one you start off with which has a fair bit of storage but takes up lots of space, flywheel batteries and chemical batteries. Now I'm assuming I need to build a chemical battery if I want better storage (seriously, the flywheels run out so fast!) but even though I've finally managed to get some sulphuric acid, I can't seem to find any vanadium. From what I can tell it's right down the bottom of the map behind those 'barrier' sectors. Is this right? I'd kind of assumed that was some kind of endgame area but I don't know how else I would get better batteries beyond the starting ones. Am I just supposed to build more flywheels?
