Bio Battery

Tech Level 44, two points. You craft it only at Production Assembly Line II, not on the basic line. One Bio Battery needs Electric Organ ×1, Refined Ingot ×1, and Carbon Fiber ×1. Work sits around 20,000, so expect a real production hit when you batch them.

Bio Battery feeds Computer and, further up, the AI Core chain. Unlock Carbon Fiber around level 35 and Assembly Line II around 42 before you lean on this craft, or you'll stare at a locked station with the recipe already purchased.

Stock Electric Organs and Carbon Fiber early once Assembly Line II is up. Computers and AI Cores will drain Bio Batteries faster than casual crafting keeps up, so treat this as a mid-ladder bottleneck rather than a one-off part.
