Ultra Cell
High-capacity FE, fluid, and chemical storage cells for Applied Energistics 2. Two tiers — Hongmeng and Wuji — with external per-cell storage, owner tracking, UUID identity, and orphan data recovery
Quick answer
Which Ultra Cell release should I use?
Ultra Cell ultracell-2.0.1.jar targets 1.21.1 with NeoForge. The project page does not say whether this file belongs on the client, dedicated server, or both. All 6 required mods have matching files.
Where it goes
Is Ultra Cell required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does Ultra Cell ultracell-2.0.1.jar need?
ultracell-2.0.1.jar. Change the file and its required mods may change too.
Install Applied Mekanistics, MEGA Cells, Applied Flux, Mekanism and 2 more first. We found matching files for this game-version and loader setup. 21 come through another mod in the chain.
21 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

# Ultra Cell
A high-capacity AE2 storage cell addon for Minecraft 1.21.1 · NeoForge 21.1.x.
Provides FE, fluid, and chemical storage cells with massive capacity, integrated into the AE2 network.
## Dependencies
- AppliedFlux
- MEGA Cells
- Applied Mekanistics (appmek)
## Cell Tiers
| Tier | FE | Fluid Slots | Chemical Slots |
|---|---|---|---|
| Hongmeng | 2^128−1 | 128 | 128 |
| Wuji | 2^192−1 | 512 | 512 |
Per-type capacity = total capacity / type slots.

| Wuji FE Cell | `ultracell:wuji_fe_component` + `ultracell:ultimate_cell_housing` |
| Hongmeng Fluid Cell | `ultracell:hongmeng_fluid_component` + `ultracell:ultimate_cell_housing` |
| Wuji Fluid Cell | `ultracell:wuji_fluid_component` + `ultracell:ultimate_cell_housing` |
| Hongmeng Chemical Cell | `ultracell:hongmeng_chemical_component` + `ultracell:ultimate_cell_housing` |
| Wuji Chemical Cell | `ultracell:wuji_chemical_component` + `ultracell:ultimate_cell_housing` |
## Commands
| Command | Permission | Description |
|---|---|---|
| `/ultracell getuuid` | Everyone | Read the UUID of the held cell; click to copy |
| `/ultracell recover <uuid>` | Everyone | Recover the cell with the given UUID |
| `/ultracell scan` | Everyone | Scan for orphan data files |
| `/ultracell trade <player>` | Everyone | Transfer cell ownership to an online player |
| `/ultracell transfer <uuid> <player>` | OP | Force-transfer ownership; works on offline players |
| `/ultracell debug` | OP | Debug utilities |
## Filtering
- No whitelist: dynamic allocation, slots released when emptied.
- Whitelist configured: only accepts whitelisted types.
- Inverter Card: rejects whitelisted types, dynamic allocation for the rest.
## Development Environment
- Minecraft 1.21.1
- NeoForge 21.1.x
- JDK 21
- Gradle Wrapper 8.13
- ModDevGradle
## How It Works
**FE cells**: stored in the item's data components (three longs). No external files; 1.0.0 saves remain compatible.
**Fluid / chemical cells**: each cell has its own `.dat` file (compressed NBT), named by UUID. Write schedule: end-of-tick merge write + shutdown write + cell-leaves-container write + 30-second fallback write. No copy protection.
**Ownership**: a cell in a player's inventory is bound to that player; a cell in an ME network belongs to the network owner; existing ownership is never rebound.
**Orphans**: never auto-deleted, kept for recovery.
