HC Valley Battery: Production & Layout Guide

HC Valley Batteries provide the highest energy yield among Valley IV battery types in Arknights Endfield and are profitable when sold to locals. However, their production chain is resource‑intensive, requiring advanced materials and large quantities of raw inputs. Originium Ore and Ferrium Ore are particularly high‑demand; shortages in either can cause a complete production shutdown. Sandflower, by contrast, is straightforward to produce.

Required Components and Layout

The compact layout uses the main core area extensively and is oriented wider rather than longer. It can also utilize three extra output ports from cores and be copied to sub‑PACs or Outposts if space permits. The essential components include:

• 19 Bus Unloader Outputs (12 Originium Ore, 3 Sandflower, 4 Steel Parts)
• 15 Shredding Units
• 6 Grinding Units
• 2 Packaging Units
• 4 Thermal Banks
• Protocol Storage Stashes for excess materials

Production Priorities

The primary production focus should be on Dense Originium Powder and Steel Parts, as other inputs are integrated into these two lines. Sandflower is easy to manufacture, so players can direct most attention to maintaining a steady supply of Originium and Ferrium Ore.
