SC Valley Battery sits at the center of mid-game power management in Arknights: Endfield. It is a factory-made battery that increases AIC power capacity when burned in Thermal Banks and can also be traded at outposts for Valley IV Stock bills.
Quick answer: SC Valley Battery is a 3★ AIC product made from Ferrium-derived parts and Originium Powder in Valley IV; each unit provides 420 Power to a Thermal Bank and can also be sold as a high-value stock item.

The in-game description frames SC Valley Battery as a packaged power item produced entirely by AIC facilities. It is not a raw resource; it always comes from processing Ferrium and Originium-based materials inside the factory.
SC Valley Battery production chain (factory mechanics)
SC Valley Battery is built through a fixed production chain that turns Ferrium and Originium into processed parts and powder before final assembly. The chain uses only AIC factory facilities.
The core steps are:
- Ferrium handling: Ferrium is moved into the Shredding and Refining Units. Shredding breaks ore into Ferrium Powder; Refining upgrades intermediate materials as needed.
- Ferrium Part creation: A Fitting Unit takes processed Ferrium and outputs Ferrium Part, an intermediate component item.
- Originium processing: Originium is ground down to Originium Powder using the appropriate processing facilities.
- Battery packaging: Ferrium Part and Originium Powder are combined in a higher-tier processing facility that outputs SC Valley Battery as the final product.
Production blueprints that focus on SC Valley Battery typically arrange several Shredding Units and Refining Units around Depot Unloaders. Materials are pulled from the Depot, processed in parallel, converged through Fitting Units for Ferrium Part, and then merged with a stream of Originium Powder to feed the final battery assembler.
Because every unit in the chain has a fixed cycle time, layouts are tuned so that Ferrium intake and Originium Powder intake match the consumption rate of the SC Valley Battery recipe. That is what allows “no downtime” battery lines: processed materials arrive just in time for every craft cycle.
SC Valley Battery and Thermal Bank power output
SC Valley Battery’s main functional role is to raise your AIC power ceiling when burned in Thermal Banks.
- Base power limit: AIC starts with a 200 Power cap. Each facility you place consumes part of this cap.
- Thermal Bank behavior: A Thermal Bank consumes specific fuel items and, while fueled, increases the Power cap for the entire AIC area.
- SC Valley Battery effect: One SC Valley Battery provides exactly 420 Power to a Thermal Bank.
High-output SC Valley Battery layouts are typically matched to multiple Thermal Banks. One example configuration produces four SC Valley Batteries at the same rate that four Thermal Banks consume them, raising the power cap by 1680 while maintaining continuous operation.
Battery distribution into Thermal Banks can follow two patterns:
- Direct belt feed: Belts and splitters route fresh SC Valley Batteries directly into each Thermal Bank input.
- Depot-based distribution: The line sends SC Valley Batteries into a Protocol Stash or PAC-connected Depot, and Thermal Banks pull them using Depot Unloaders. This avoids uneven splitter behavior and keeps Thermal Banks supplied from a shared pool.
Thermal Banks show their fuel status on the facility UI. Continuous SC Valley Battery consumption with no idle time is the signal that the production chain and distribution setup are correctly balanced.
SC Valley Battery in outpost trading and stock generation
SC Valley Battery is also treated as a trade good for regional development. In Valley IV, it can be exchanged for Stock bills at outposts.
- Stock bill role: Valley IV Stock bills are used for regional upgrades and purchases in Stock Redistribution and related shops.
- Battery conversion: SC Valley Batteries can be traded directly for these bills, so any surplus from your power setup becomes currency input for outpost progression.
- Factory alignment: Mid-game factory layouts often dedicate part of their SC Valley Battery output to Thermal Banks and route the rest to Protocol Stash or outpost delivery.
Because Stock bills lose value once major upgrades and shop items are exhausted, long-term layouts may eventually redirect more SC Valley Battery output into power or other recipes instead of trading. During the early and mid stages of Valley IV, however, SC Valley Battery is one of the most efficient Stock bill sources inside the factory system.
SC Valley Battery, therefore, serves two simultaneous functions in Arknights: Endfield: It is the main mid-tier fuel for scaling AIC power through Thermal Banks, and it is a high-value stock item for Valley IV’s regional economy. Any factory layout that maintains a stable flow of Ferrium Part and Originium Powder will reliably convert those resources into sustained power and currency through SC Valley Batteries.
