Battery upgrades: capacity, materials and energy costs

A battery holds the energy you carry. Energy stations provide refills. Increase battery capacity when a single craft costs more charges than your current battery can hold; add generators when you need more stored energy available for repeated refills.

Upgrade capacities and crafting costs

Battery	Capacity	Energy spent crafting the upgrade
Starting Battery	Five charges	Supplied in opening progression
Battery Lv.2	Ten charges	Three charges
Battery Lv.3	Twenty charges	Ten charges
Battery Lv.4	Thirty charges	Fifteen charges

The finished battery’s capacity is not the cost to craft it. Battery Lv.2 requires three charges from the starting five-charge battery. Battery Lv.3 costs the full ten-charge capacity of Battery Lv.2, so charge before crafting it.

Materials and station levels

Upgrade	Ingredients	Required station
Battery Lv.2	Previous Battery, ten Scrap Wire, two Mushroom Leather	Project Station Lv.1
Battery Lv.3	Previous battery, three Copper Bar, two Lignin	Project Station Lv.2
Battery Lv.4	Previous battery, ten Power Cable, five Circuit Boards, ten Vines	Project Station Lv.3

The upgrade consumes the previous battery. Obtain the recipe and materials before starting, then check that you can pay the energy cost from the battery you currently carry.

Elemental Earth at the Overgrowth Research Station unlocks the Battery Lv.3 recipe. Sightless Seekers at that station unlocks Battery Lv.4. Project Station Lv.3 is part of the Gridfall repair progression.

Prepare Lignin for Battery Lv.3

Lignin uses five Bioluminescent Ivy at a Refining Station Lv.2. The battery needs two Lignin, so reserve ten Ivy for that ingredient. Gathering Ivy requires Pruners Lv.2; the ivy route explains the research and tool upgrade.

That ten-Ivy total covers Lignin only. Any Ivy currently needed by a quest or research bundle is additional.

Add a second energy station

Your island initially allows one Energy Station. The first permit increase costs 125 Dew and allows two. A larger allowance changes how many generators you may place, not the capacity of the battery itself.

If a recipe costs ten charges and you still carry the five-charge starting Battery, two full generators do not let that battery hold ten at once. Craft Battery Lv.2 first.

Early Access patch #1 fixes capacity being lower than a battery you own by correcting it on login or map travel. Check the corrected capacity after traveling if an owned upgrade is not reflected in the display.

Station storage and crafting totals

Generator choices compare solar, wind, hydro and biofuel unlocks and storage. For a multi-stage upgrade, material chains separates refining energy from the final payment so cumulative spending is not confused with required carrying capacity.
