Energy Crystal — Minecraft block
Energy Crystal
Energy Crystal is an HV-tier Industrial Craft 2 battery storing 1,000,000 EU, pressed from Energium Dust to power high-voltage IC2 tools and machines.
Description
Energy Crystal powers HV-tier IC2 tools and machines from their internal charge slot: a single charged crystal keeps a Mining Laser or a full Nano armor set running far longer than a 10,000 EU RE-Battery. Recharging happens in an MFE (512 EU/t) or an MFSU (2048 EU/t), or by right-clicking with the crystal in hand to recharge the electric tools and armor on the hotbar. Energy Crystal is also the center ingredient of the Lapotron Crystal — with 2 Advanced Circuits above and below it and 6 Lapis Lazuli Dust in the remaining slots — stepping up to 10,000,000 EU of tier-4 storage.

Guide
How to craft and use Energy Crystal in Minecraft
-
1
Gather the ingredients
Collect 4 diamonds and 5 redstone dust, then grind the diamonds in a Macerator into 4 Diamond Dust. Industrial Craft 2 must be installed on a Minecraft 1.12.2 client and server.
-
2
Craft Energium Dust
On a crafting table place Diamond Dust in the 4 edge slots and redstone dust in the center and the 4 corners; one batch yields 9 Energium Dust.
-
3
Press Energy Crystal
Put 9 Energium Dust and a charged RE Battery into a Compressor to press a single Energy Crystal, which comes out with zero charge.
-
4
Charge Energy Crystal
Place Energy Crystal in the charge slot of an MFE Unit (512 EU/t) or MFSU (2048 EU/t) fed by a generator until it holds 1,000,000 EU.
-
5
Power HV tools or craft a Lapotron Crystal
Slot the charged Energy Crystal into a Mining Laser or Nano armor, or place Energy Crystal in the center with 2 Advanced Circuits above and below and 6 Lapis Lazuli Dust in the remaining slots to craft a 10,000,000 EU Lapotron Crystal.
Energy Crystal outputs at the HV tier (512 EU/t); lower-tier machines burn out instantly unless Transformer Upgrades are installed.
Frequently asked questions
How much energy can Energy Crystal store?
Energy Crystal stores up to 1,000,000 EU at the HV tier and discharges at 512 EU/t, or 2048 EU/t when drawn from an MFSU.
What is the crafting recipe for Energy Crystal?
Energy Crystal is pressed in a Compressor from 9 Energium Dust plus a charged RE Battery; Energium Dust is crafted from 5 Redstone Dust and 4 Diamond Dust on a crafting table.
How do I charge an Energy Crystal?
Place Energy Crystal in the charge slot of an MFE Unit or MFSU; a freshly pressed Energy Crystal is completely empty and must be charged before use.
Can Energy Crystal power lower-tier machines directly?
No — Energy Crystal outputs at the HV tier, so lower-tier machines explode unless Transformer Upgrades are installed in them.
How does Energy Crystal compare to RE-Battery and Lapotron Crystal?
RE-Battery is tier 1 with 10,000 EU, Energy Crystal is tier 3 with 1,000,000 EU, and Lapotron Crystal is tier 4 with 10,000,000 EU, crafted around an Energy Crystal.
Does Energy Crystal stack?
Energy Crystal stacks up to 16, but only when every crystal in the stack has exactly the same charge.
