What are small energy cells? They're not fission or fusion, so I guess an electric battery is a fair assumption? Isn't that what an electron charge pack is? Then why do SECs have more energy in them than ECPs (going by conversion recipes)? And what about the recycling and conversion recipes? Do you just have an unlimited supply of empty (I want to say) cartridges for each type on hand? Like how 1 fission battery and 5 drained SEC creating 25 SEC materializes 20 empty SECs to 'fill up'. I take it the they all have leftover energy in them, which sort of begs the question of why they weren't designed to drain anywhere close to fully (e.g 1/3rd leftover for SEC). I feel like I had more questions but sleep is calling.
