ExtraCells Mod — Guide
Fluid Storage Mechanics
Fluid storage in ExtraCells 2 follows the same logic as item storage in AE2 but uses different units. Fluids are measured in milliBuckets (mB), where 1,000mB equals 1 bucket.
Storage Math
By default, the mod uses a conversion ratio where 1 Byte = 8,000 mB (8 Buckets). However, this is highly configurable. Each fluid storage cell can hold up to 5 different types of fluids.
| Cell Tier | Byte Capacity | Total Fluid Capacity (Default) |
|---|---|---|
| 1k Fluid | 1,024 | 8,192,000 mB (8,192 Buckets) |
| 4k Fluid | 4,096 | 32,768,000 mB (32,768 Buckets) |
| 16k Fluid | 16,384 | 131,072,000 mB (131,072 Buckets) |
| 64k Fluid | 65,536 | 524,288,000 mB (524,288 Buckets) |
| 256k Fluid | 262,144 | 2,097,152,000 mB |
| 1024k (1M) | 1,048,576 | 8,388,608,000 mB |
| 4096k (4M) | 4,194,304 | 33,554,432,000 mB |
Note: Unlike item cells, fluid cells do not have a 'type limit' penalty that consumes bytes; they simply have a fixed capacity for up to 5 types.
Storage Cells and Components
ExtraCells 2 adds several tiers of storage cells for items, fluids, and gases. Each cell consists of a Storage Component placed inside a Storage Housing.
ME Item Storage Cells
These cells function exactly like AE2 item cells but offer significantly higher capacities.
- 256k ME Storage: Holds 262,144 bytes.
- 1024k (1M) ME Storage: Holds 1,048,576 bytes.
- 4096k (4M) ME Storage: Holds 4,194,304 bytes.
- 16384k (16M) ME Storage: The largest cell available, holding 16,777,216 bytes.
ME Fluid Storage Cells
Used to store liquids within the network. They require a Fluid Storage Housing (blue-tinted). * Tiers: 1k, 4k, 16k, 64k, 256k, 1024k, 4096k.
ME Gas Storage Cells
If Mekanism is installed, these cells allow the storage of gases. They use the same tier system as fluid cells but are specifically for chemical gases.
Specialized Cells
- Adjustable ME Storage: A cell that can be partitioned and limited to specific amounts of items via a GUI.
- Encryptable ME Storage: A security-focused cell that can be locked to specific users.
- ME Block Container: A specialized cell designed to store entire blocks (often disabled in standard 1.7.10 builds pending rewrites).
Miscellaneous
The Walrus
A decorative block added as an easter egg. It is a small, stationary walrus that can be placed in the world. It has no functional purpose other than being a walrus.
Soldering Station
A legacy utility block used to upgrade storage cells. By placing a lower-tier cell and the necessary components into the station, players can upgrade the cell's capacity without losing the items or fluids currently stored inside.
