I puted transformer upgrade on advanced miner (teorically with 1 is enough however i put 5. Even with 1 or 5 i'm unable to put charging lapotron crystal or lapotron crystal as energy source in the advanced miner. Is that a bug?
It's a bug, transformer upgrades change the tier of power the advanced miner can accept, but don't change the tier the battery slot can take. It will be fixed in the next build.
