Getting your factory running smoothly in Arknights Endfield means dealing with one inevitable problem: power. As you keep expanding your base and adding more machines, basic Originium Ore eventually falls short. That’s where batteries come in, serving as your reliable energy solution for larger operations.
If you’re diving into the factory-building aspects of the game, check out our complete Arknights Endfield guides hub for more helpful resources on managing your base effectively.
Understanding Battery Requirements
Before you start building production lines, you need to know what goes into making batteries. These aren’t simple items you craft from raw materials—they require processed components from multiple production chains.
Here’s what you’ll need:
Amethyst Parts – Created through a two-step process where you refine Amethyst Ore into Amethyst Fiber first
Originium Powder – Produced by running Originium Ore through a Shredding Unit
The battery crafting recipe unlocks through the Power I node in your AIC Index menu. This same unlock gives you access to Thermal Banks, which burn batteries to generate substantial power for your base.
One quick note: this guide covers LC Valley Batteries made with Amethyst. SC Valley Batteries follow identical production methods but swap Amethyst for Ferrium instead.
Building Your Component Production Lines
Start by setting up dedicated lines for your raw materials. You’ll want separate production chains for Originium Powder and Amethyst Parts running independently before connecting everything together.
For each line, connect your machines to your PAC (Protocol Assembly Controller) properly. The key is making sure each chain terminates at a Protocol Stash or loops back to your PAC input ports—this prevents material buildup and keeps everything flowing.
Once your component lines are running, add a Packaging Unit connected to two Thermal Banks. This setup, when supplied properly, generates an additional 440 power units for your base operations.

Two Approaches to Battery Production
You’ve got options when designing your battery production system, each with distinct advantages:
Centralized Component Production
This method creates large, shared production lines for Amethyst Parts and Originium Powder that your entire factory can draw from. Your battery Packaging Unit simply taps into these existing supply chains.
The advantage? Maximum flexibility. All your buildings access the same material pools, reducing redundancy.
The drawback? Supply and demand balancing becomes critical. If you expand without properly scaling component production, everything downstream suffers.
Self-Contained Battery Lines
This approach builds dedicated component production exclusively for battery manufacturing. Your Packaging Unit gets its own Amethyst and Originium processing chains that don’t share with other factory operations.
The advantage? Simplicity. Just keep Originium and Amethyst ore flowing in, and batteries keep coming out. No worrying about other production lines stealing your materials.
The drawback? Space consumption and power efficiency. The production line itself eats a significant chunk of the power it generates, and you’ll need considerable factory space to fit everything comfortably.

Ready-Made Blueprint Solution
Want to skip the manual building process? Use this blueprint code for a compact, self-contained battery production setup:
EFO01O4a546i90I89oe4
This blueprint delivers perfectly balanced production—6 LC Valley Batteries per minute. The design maxes your power capacity at 640 units, with room to expand to 1080 by adding two more Thermal Banks without affecting battery output.
The layout efficiently manages Amethyst Fiber and Originium Powder consumption, preventing bottlenecks while maintaining consistent battery production.
Power Management Tips
Getting batteries flowing is just the start. Here are some practical considerations for managing your power infrastructure:
Monitor your power consumption regularly. As you add machines and expand operations, your energy demands grow faster than you might expect.
Consider scaling horizontally rather than vertically. Multiple smaller battery production setups often prove easier to manage than one massive centralized system.
Balance your Thermal Bank placement. Spreading them across your factory reduces transmission losses and provides redundancy if part of your power grid experiences issues.

Frequently Asked Questions
What’s the difference between LC Valley and SC Valley Batteries?
Both battery types function identically and follow the same production process. The only difference is the metal component used, LC Valley Batteries require Amethyst Parts, while SC Valley Batteries need Ferrium Parts instead. Choose based on which ore you have more abundant access to in your current area.
How much power do batteries actually provide?
Each Thermal Bank consuming batteries generates 220 power units. A basic two-bank setup connected to one Packaging Unit produces 440 units total. You can expand this to 1080 units by adding more Thermal Banks, though you’ll eventually need multiple production lines to keep up with consumption.
Should I build one large battery production line or several smaller ones?
Smaller, distributed production lines typically work better. They’re easier to troubleshoot when problems arise, require less upfront space investment, and let you scale gradually as power demands increase. One massive centralized system might seem efficient but becomes difficult to manage and upgrade.
Do I need to unlock anything special before making batteries?
Yes, you need to research the Power I node in your AIC Index menu. This unlocks both the battery crafting recipe and Thermal Banks. Without this research node completed, you won’t have access to battery production regardless of whether you have the necessary materials.
