Don't want to doublepost, but I don't think this suggestion will fit when I edit it in.
Basically it is about large multiblock storage units, for items, liquids and energy, called Multi-Block Storage Units (MBSU)
To build one, you will need to use MBSU Frames and Multi-Block Storage Extension Covers MBSU Cover Blocks. They can be made by:
MBSU Frames
A - A
B C B --> 4
B A B
A is Steel Plates / Stainless Steel Plates
B is Iron Rod
C is Wrench
Can also be made by assembling 3 Steel Plates / Stainless Steel Plates and 4 Iron Rods for 5000 EU at 128 EU/t.
MBSU Cover Blocks
A B C
A D C --> 6
A B C
A is Steel Plates / Stainless Steel Plates
B is Iron Rod
C is Lead Plates
D is Wrench
A complete MBSU unit is a cuboidal structure with MBSU Frames as edges and vertices, and MBSU Cover Blocks as faces. The maximum external length in each dimension is 16 blocks. Replace one of the MBSU Cover Blocks with one of the following units:
MBSU Core Unit
The MBSU Core Unit is needed for the entire structure to function. The MBSU Core Unit comes in 4 different variants: Solid Storage, Fluid Storage, Solid Electrolyte and Fluid Electrolyte. Upgrades for the MBSU are added to the Core Unit.
The crafting recipes are:
Solid Storage Component
A B A
B C B --> 1
A B A
A is Iron Plate
B is Lead Rod
C is Wrench
Liquid Storage Component
A B A
B C B --> 1
A B A
A is Copper Plate
B is Electrum Rod
C is Wrench
MBSU Solid Storage Core
Shapeless: Solid Storage Component + MBSU Cover Blocks + Data Orb + Conveyor Module + Wrench
MBSU Fluid Storage Core
Shapeless: Fluid Storage Component + MBSU Cover Blocks + Data Orb + Pump Module + Wrench
MBSU Solid Electrolytic Core
Shapeless: Solid Storage Component + MBSU Cover Block + Energy-flow Circuit + MV-Transformer + Wrench
MBSU Fluid Electrolytic Core
Shapeless: Fluid Storage Component + MBSU Cover Block + Energy-flow Circuit + MV-Transformer + Wrench
MBSU IO Units
The IO Units are used to input items into the MBSU as well as output items from the MBSU. They come in item and fluid variants. They are just crafted by Conveyor Module / Pump Module + Machine Casing + Wrench.
MBSU Electrodes
The MBSU Electrodes are used to input energy into and out of the MBSU. They come in cathode (negative; energy in) and anode (positive; energy out) variants.
Compacted Graphite is made by compressing 16 Carbon Cells. It can be macerated into 16 Carbon Dust.
MBSU Cathode
Shapeless: Silver Plate / Compacted Graphite / Platinum Plate + MV Transformer + Redstone Dust + Lapis Lazuli Block +Wrench
MBSU Anode
Shapeless: Silver Plate / Compacted Graphite / Platinum Plate + MV Transformer + Redstone Torch + Lapis Lazuli Block + Wrench
The MBSU Solid/Liquid Storages in General
MBSU Solid/Liquid Storages can store up to 2 full units of items per metre cubed inside the frame. This can be increased with Density Upgrades which can be crafted from 2 double lead plates, a wrench, and a screwdriver. There can be a maximum of 8 Density Upgrades, which each increase the maximum capacity by 1 full unit of items per metre cubed. This maxes out at 20 full units of items per metre cubed inside the frame. The MBSU Solid Storage can store only 1 type of item, but this can be expanded up to 6 types with 5 more Type Recognition Upgrades, which are crafted from 1 glass, 1 slimeball, 1 ender pearl dust, 1 lead plate and 1 screwdriver each. The MBSU Liquid Storage can only store 1 type of liquid.
The number of items in 1 full unit depends on the item itself. If the item is registered as dustTiny, 1 full unit is 36 stacks; dustSmall is 16 stacks; dust is 4 stacks; ingot is 2 stacks; block is 1 stack. Other items are assumed to be 2 stacks (configurable).
For liquids, 4000 mB is considered 1 full unit.
The MBSU Solid/Liquid Electrolytes in General
MBSU Solid/Liquid Electrolyte store enough electricity based on the electrolyte used. Electrolytes are added through IO Units, but they cannot be extracted.
2 Lead Plates + 750 mB Sulfuric Acid per 1 metre cubed: 20 000 EU per metre cubed
1 Nickel Plate + 1 Cadmium Plate* per 1 metre cubed: 20 000 EU per metre cubed
1 Nickel Plate + 1 Lithium Cell per 1 metre cubed: 10 000 EU per metre cubed
4 Lithium Cells per 1 metre cubed: 15 000 EU per metre cubed
