Bio Battery is crafted, not looted - one Electric Organ, one Refined Ingot, and one Carbon Fiber make one at the Production Assembly Line II, unlocked at Technology Level 44. No Pal drops it and no chest contains it, so the only way to get one is to build it. It then feeds a huge slice of the 1.0 endgame: energy weapons like the Plasma Rifle and Beam Launcher, their ammo, and a wall of high-tech structures from the Computer to the Electric Furnace. This guide gives the exact recipe, how to unlock and craft it without the two common mistakes, the fastest way to farm the ingredients, and every single thing it builds.
The thing to know up front: the recipe is trivial, but Electric Organs are the bottleneck. Solve that supply and Bio Battery stops holding up your tech tree. This is one of the core 1.0 assembly-line materials - see our new resources and materials guide for how the whole chain fits together.

The Recipe and Its Ingredients
The recipe is a clean one-to-one-to-one: 1 Electric Organ + 1 Refined Ingot + 1 Carbon Fiber = 1 Bio Battery. The in-game description calls it a device that stores bio-energy as electrical power, used for equipment requiring high energy density. Each ingredient comes from a different source, and only one is a real hurdle:
Ingredient | Where it comes from |
|---|---|
Electric Organ | The bottleneck - hunt Electric Pals, or capture settlement merchants (they carry two organs at once) |
Refined Ingot | Smelt at an Improved, Electric, or Large furnace |
Carbon Fiber | Unlocked at Level 35; made from Flame Organ plus Charcoal or Coal |
Refined Ingot and Carbon Fiber are steady base-production items once your furnace and Carbon Fiber line are running. The Electric Organ is the one you will run short on, because it only comes from hunting.
How to Unlock and Craft It
Three steps, and two mistakes that stop most players:
- Reach Technology Level 44 and spend 2 Technology Points to unlock Bio Battery. Below Level 44 it does not appear in the tech tree at all.
- Build a Production Assembly Line II. This is the common trap: the recipe only shows on the second-tier line (available from Level 42), never the basic Production Assembly Line. If you cannot find the recipe, this is why.
- Assign strong workers. Each Bio Battery is a 20,000-work craft, so it crawls with weak Pals. Put several high-Handiwork Pals on the line and keep the ingredients flowing.
Also unlock Carbon Fiber at Level 35 first - skipping it leaves you permanently one ingredient short. For staffing the line efficiently, our best base Pals guide covers the top Handiwork workers.
Farming the Ingredients Fast
The whole difficulty of Bio Battery is the Electric Organ supply. It is not produced passively at a Ranch, so every one has to be hunted. Two efficient routes:
- Hunt Electric Pals in bulk - any electric-type creature drops Electric Organs, so a farming loop through an electric-heavy region stocks you fast.
- Capture settlement merchants and NPCs. Human enemies from small settlements can carry two organs at once - Electric Organ and Flame Organ - so clearing a camp doubles up as Carbon Fiber material too.
Meanwhile, keep Refined Ingot smelting at an upgraded furnace and Carbon Fiber flowing (Flame Organ plus Charcoal or Coal - a Flambelle on a Ranch keeps the Flame Organs coming). With all three streams running, Bio Battery becomes a background batch rather than a stop-and-go grind.
The clean setup is one base built around this loop: a furnace line turning ore into Refined Ingot, a Carbon Fiber line fed by a Flambelle Ranch, and an Electric Organ stockpile from a hunting route or a butcher line. Feed all three into a Production Assembly Line II staffed with high-Handiwork Pals, and the batteries accumulate while you do other things. Because each craft is 20,000 work, the number of workers on the line matters more than anything - a single weak Pal will bottleneck the whole operation no matter how many organs you have.
Double Your Electric Organ Yield
The trick almost nobody applies to material farming: a captured Pal pays out its drops twice. Capturing it awards the organs, and then butchering it with a Meat Cleaver rolls the same drop table again. Add a Pal with the Service-Minded or Lavish Hospitality passive and both payouts increase by 50% or 100%. Breed a butcher line of an Electric Pal with those passives and your Electric Organ shortage disappears - our Service-Minded guide covers building that loop.
Weapons That Need Bio Battery
Bio Battery is the backbone of the energy-weapon tier. Every top firearm draws on it, and the quantities are steep:
Weapon | Bio Battery | Tech Lv |
|---|---|---|
Plasma Rifle | 50 | 78 |
Beam Launcher | 50 | 80 |
Laser Sword | 30 | 73 |
Heavy Assault Rifle | 30 | ~70 |
Plasma Multicutter | 30 | 54 |
Charge Rifle | 25 | Mid-endgame |
Laser Rifle | 5 | Mid-endgame |
The Plasma Rifle and Beam Launcher each need 50 per craft, and schematic-upgraded versions cost even more. If you are building toward the endgame arsenal, Bio Battery demand scales fast - see our weapons tier list for which of these to build first.
Ammo That Needs Bio Battery
It is not just the weapons - their ammo runs on Bio Battery too, so it is a permanent upkeep cost once you switch to energy guns:
Ammo | Feeds |
|---|---|
Plasma Rifle Ammo | Feeds the best all-round endgame firearm |
Beam Launcher Ammo | Feeds the top AoE payload weapon |
Beam Scatter Ammo | Energy shotgun rounds |
Charge Rifle Ammo | Charge Rifle rounds |
Energy Shotgun Ammo | Energy shotgun rounds |
Laser Gatling Cartridge | Laser Gatling Gun rounds |
Energy Cartridge | General energy-weapon cartridge |
This is the reason a mid-game material never stops mattering: every energy-weapon fight quietly consumes Bio Battery through the cartridges. Keep a standing stockpile or you will run dry mid-boss.
Structures and Tech That Need Bio Battery
The third demand sink is your base itself - a long list of high-tech structures require it:
Structure | Bio Battery | What it does |
|---|---|---|
Computer | 2 | Gates AI Cores and high-tech crafting |
Electric Furnace | Several | Faster smelting |
Item Retrieval Machine | Several | Auto-collects base output |
High-Pressure Crude Oil Extractor | Several | Automates crude oil |
Advanced Workshop / Ancient Workbench | Several | The endgame crafting stations themselves |
Weapon Assembly Line II | Several | Faster weapon crafting |
Mounted Missile Launcher | Several | Base-defense turret for raids |
Electric Pylon, Beta Wave Generator, lamps | Several | Power and lighting infrastructure |
The most important is the Computer, since it gates AI Cores and the deepest crafting tier. The rest are the industrial and power backbone of an endgame base - furnaces, extractors, retrieval machines, and the crafting stations themselves.
Where Bio Battery Sits in the Material Chain
Bio Battery is one of five interlocking 1.0 assembly-line intermediates, and understanding the order they unlock in saves you a stalled tech tree. The chain runs Cryogenic Coolant (Level 31), Corrosive Solvent (Level 37), Bio Battery (Level 44), Computer (Level 50), and Thermal Core (Level 59), with AI Cores sitting on top at Level 67. Bio Battery feeds directly into the Computer, and Computers plus Thermal Cores then feed the AI Cores behind nearly every top weapon, so a shortage here bottlenecks the entire endgame. Build your Production Assembly Line II early and keep the battery line running in the background, because by the time you need Computers you will want Bio Batteries by the dozen already in storage. Our Cryogenic Coolant guide covers the sibling material one tier down.
How Much Should You Stockpile?
Add up the three demand sinks and Bio Battery becomes a hundreds-of-units material. A single endgame weapon set alone runs well past 100 (the Plasma Rifle and Beam Launcher want 50 each), the structures add dozens more, and ammo is a continuous drain on top. The practical approach: batch-craft it, never one at a time. Farm Electric Organs in bulk on a dedicated route, keep Refined Ingot and Carbon Fiber streams running, and let a well-staffed Production Assembly Line II churn out batches whenever you are at base. Keep a stack in a chest near your Ancient Workbench so an endgame craft never stalls for the want of a few batteries.
Tips and Common Mistakes
- Use the Production Assembly Line II. The recipe never appears on the basic line - this is the top reason players think it is missing.
- Electric Organs are the bottleneck. They have no Ranch source, so hunt Electric Pals and settlement merchants ahead of need.
- Unlock Carbon Fiber at Level 35 first. Skip it and you are stuck one ingredient short even at Level 44.
- Assign strong Pals. At 20,000 work per craft, weak workers make it crawl.
- Capture merchants for double organs. Settlement humans carry Electric and Flame Organ at once - two Bio Battery ingredients in one clear.
- Do not expect to loot it. Bio Battery is crafted only; there is no drop, chest, or vendor source.
- Batch it and stockpile. Weapons, ammo, and structures all pull from the same pool - keep hundreds on hand.

FAQ
What is the Bio Battery recipe in Palworld?
One Electric Organ, one Refined Ingot, and one Carbon Fiber make one Bio Battery. You craft it at the Production Assembly Line II after unlocking it at Technology Level 44 for 2 points. It cannot be looted from Pals, chests, or vendors - crafting is the only source.
Why can't I find the Bio Battery recipe?
Because it only appears on the Production Assembly Line II (available from Level 42), not the basic Production Assembly Line. You also need to be Technology Level 44 with the recipe unlocked. If you built the first-tier line, the recipe will never show - upgrade to the second-tier one.
How do you farm Electric Organs for Bio Battery?
Hunt Electric-type Pals, which drop Electric Organs, or capture settlement merchants and NPCs - human enemies can carry both an Electric Organ and a Flame Organ at once. Electric Organs are the bottleneck since they have no passive Ranch source, so stockpile them ahead of need. Capturing then butchering a Pal rolls its drops twice.
What is Bio Battery used for in Palworld?
A lot. It feeds the energy-weapon tier (Plasma Rifle and Beam Launcher need 50 each, plus the Laser Sword, Heavy Assault Rifle, Plasma Multicutter, and Charge Rifle), all of their ammo, and a wall of high-tech structures including the Computer, Electric Furnace, Item Retrieval Machine, and the Ancient Workbench itself.
Can you get Bio Battery without crafting it?
No. Bio Battery is a crafted material only - it does not drop from Pals or bosses, is not found in chests or dungeons, and is not sold by vendors. You gather its three ingredients and synthesize it at the Production Assembly Line II. There are no shortcuts to the item itself.
What level do you unlock Bio Battery?
Technology Level 44, for 2 Technology Points. You also need Carbon Fiber (unlocked at Level 35) as an ingredient and a Production Assembly Line II to craft on. Reaching Level 44 without those prerequisites still leaves you unable to make it.
How much Bio Battery do you need?
Hundreds over a full endgame playthrough. The Plasma Rifle and Beam Launcher want 50 each, other weapons 5 to 30, high-tech structures add dozens, and energy-weapon ammo is a continuous drain. Batch-craft it and keep a standing stockpile rather than making it on demand.
