Bio Battery is a late-game Palworld material unlocked at level 44 and crafted at Production Assembly Line II using Refined Ingot, Carbon Fiber, and Electric Organ.
Bio Battery is one of those late-game parts that feels hidden until you realize there is no map marker for it at all. You do not loot it from a boss or dig it out of a chest — you build it. Once you push your technology tree to level 44 and have Production Assembly Line II standing at your base, the recipe becomes a straightforward matter of stocking three ingredients and letting strong worker Pals grind through the craft.
Bio Battery unlock level and crafting station
| Requirement | Answer |
|---|---|
| Unlock level | Level 44 in the technology tree |
| Crafting station | Production Assembly Line II |
| Ingredients | Refined Ingot, Carbon Fiber, Electric Organ |
| World location | None — Bio Battery is crafted, not found |
KEY!
The short version: Bio Battery lives in the high-level industrial section of the technology tree, and the only “location” that matters is your own base workshop. Reach the required tier, spend your technology points, and craft it at Production Assembly Line II — the basic line will never show the recipe.
How to craft Bio Battery in Palworld
Getting Bio Battery is a chain of unlocks and ingredient runs that all funnel into one final craft at Production Assembly Line II.
STEP 1/6
Open the technology tree
Head into the technology tree and scroll up to the high-level industrial tiers where the late-game parts sit.
STEP 2/6
Unlock Bio Battery at level 44
At level 44 you will find Bio Battery — spend your technology points to unlock the recipe.
STEP 3/6
Smelt Refined Ingot at a furnace
Bio Battery needs Refined Ingot, which requires at least an improved furnace (an electric or large furnace also works).
STEP 4/6
Make Carbon Fiber after unlocking it at level 35
Carbon Fiber unlocks at level 35 and is produced at a production assembly line from coal and a Flame Organ, or from charcoal and Flame Organs instead.
STEP 5/6
Gather Electric Organs
Kill Electric Pals for Electric Organ, or capture merchants and settlement NPCs and haul them back to farm both Electric and Flame Organs.
STEP 6/6
Craft at Production Assembly Line II
With all three ingredients ready, go to Production Assembly Line II and craft your Bio Batteries.

Where to get every Bio Battery ingredient
| Material | How to get it |
|---|---|
| Refined Ingot | Smelt at an improved, electric, or large furnace |
| Carbon Fiber | Unlock at level 35, then craft at a production assembly line from coal + Flame Organ, or charcoal + Flame Organ |
| Electric Organ | Kill Electric Pals, or capture merchants and small-settlement NPCs (they carry Electric and Flame Organs) |
Each of the three ingredients has its own small supply chain, and Carbon Fiber is the one that trips people up because it hides a second organ inside it. Here is how each piece comes together.
Refined Ingot is the easy one — smelt it at any furnace above the basic tier. Carbon Fiber is the deeper chain: unlock it at level 35, then craft it at a production assembly line using coal and a Flame Organ. If coal is tight, smelt charcoal at a furnace and pair that with Flame Organs instead. Electric Organ drops from Electric Pals, but the faster play is to capture merchants or grab NPCs from a small settlement — settlement captures come carrying both Electric Organ and Flame Organ, which knocks out two of your chains in one trip.
Capture and haul back a merchant or NPC from a small settlement — they come stocked with both Electric Organ and Flame Organ, covering the Carbon Fiber and Electric Organ chains in a single run.
Finding Bio Battery: drops, chests, and farming
There is no shortcut here worth chasing. Bio Battery is a crafted material, full stop — there is no dungeon route, chest, Pal drop, or vendor stall that hands you one directly, and any such source stays unconfirmed for the 1.0 update. Treat “farming Bio Battery” as farming its ingredients, not hunting the item on the map.
The real bottleneck is the work cost. Each Bio Battery craft carries a hefty 20,000 work, so hand-crafting or leaning on weak Pals makes the whole thing feel impossibly slow. Assign several high-work Pals to your Production Assembly Line II, keep a steady stockpile of Refined Ingot, Carbon Fiber, and Electric Organ flowing in, and the batteries pile up at a pace you can actually build with. Exact per-craft ingredient amounts can vary, so plan this as a repeat-farm setup rather than a one-and-done craft.
Common mistakes when crafting Bio Battery
Most of the trouble comes down to a missing prerequisite or the wrong workbench. Using Production Assembly Line I or an earlier bench will never surface the recipe — it has to be the second-tier line. Not reaching level 44 keeps Bio Battery hidden in the tech tree entirely, and skipping the level 35 Carbon Fiber unlock leaves you stuck one ingredient short. Two more snags round it out: throwing weak Pals at that 20,000-work craft, and expecting Bio Battery to drop as loot when it only ever comes from your own production line.
What Bio Battery is used for
Bio Battery is a device that stores bio-energy as electrical power, and it feeds the top end of Palworld’s tech. It shows up in high-density gear and machinery — the Laser Sword alone eats 30 Bio Batteries per craft (alongside Soralite Ingots and AI Cores), and advanced base tech like Computers also calls for several each. It weighs 5 per unit, so a working stockpile will start to bite into your carry weight, which is one more reason to craft in batches at base rather than lugging them around.
Frequently Asked Questions
What level unlocks Bio Battery in Palworld?
Bio Battery unlocks at level 44 in the technology tree, in the high-level industrial tier. If you cannot see it yet, you have not reached the required level.
Where do you craft Bio Battery?
At Production Assembly Line II. The basic production line will not display the recipe, so you need to build and unlock the second-tier line first.
Can you find Bio Battery as a drop or chest item?
No. Bio Battery is crafted, not found — there is no confirmed mob drop, dungeon, chest, or vendor source for it in the 1.0 update. Farming it means farming its ingredients.
How do you get Electric Organs quickly?
Kill Electric Pals for the drop, or capture merchants and NPCs from a small settlement and bring them back — settlement captures carry both Electric Organ and Flame Organ, saving you a separate farming trip.
Why is Bio Battery not showing up in my crafting menu?
Usually one of four things: you are at the wrong station (it must be Production Assembly Line II), you have not hit level 44, you never unlocked Carbon Fiber at level 35, or you are missing an ingredient in your storage.

What is Bio Battery used for?
It powers late-game tech. The Laser Sword needs 30 per craft, and machinery such as Computers and other advanced base tech each require multiple Bio Batteries.
