Been looking through the tech tree and I can't find any "Lithium" and it also disables the "lithia water" spawns from bob's mod. Loaded up my old world and let it rush through all the research and didn't find any path to Lithium...
I have no clue how you can get to T2 batteries... The Bob's Mod's recipes are still there but there's no Lithia Water to get or any way to convert Omnimatter into Lithium (or any of its many derivatives).
