Description

Energy Crystal is a Medium Voltage (MV) portable battery from Industrial Craft 2 that stores up to 100,000 EU and outputs at the MV tier of 128 EU/t. Energy Crystal is crafted on a vanilla Crafting Table from one Diamond in the center surrounded by 8 Redstone Dust, making Energy Crystal the natural next step after the basic RE-Battery, which only holds 10,000 EU at low voltage. The red, faceted texture of Energy Crystal makes Energy Crystal easy to spot in the inventory alongside other IC2 storage items.

Energy Crystal powers MV-tier IC2 tools and machines when slotted into their internal charge slot, so an Energy Crystal keeps a Diamond Drill, Chainsaw, or higher-tier mining device running far longer than an RE-Battery would. To recharge an Energy Crystal, place Energy Crystal inside an MFE Unit, or drop Energy Crystal into the player charge slot of an MFE or MFSU. Energy Crystal is also the core ingredient of the Lapotron Crystal, the High Voltage successor that stores 1,000,000 EU, which makes Energy Crystal a key crafting step on the IC2 energy progression path.

Guide

How to craft and use Energy Crystal in Minecraft

  1. 1

    Gather the ingredients

    Collect 1 Diamond and 8 Redstone Dust. Industrial Craft 2 must be installed on a Minecraft 1.12.2 client and server.

  2. 2

    Craft Energy Crystal

    Open a vanilla Crafting Table, place the Diamond in the center slot and fill the other 8 slots with Redstone Dust to craft Energy Crystal.

  3. 3

    Charge Energy Crystal in an MFE

    Place Energy Crystal in the charge slot of an MFE Unit fed by a Generator or Solar Panel; the MFE charges Energy Crystal up to 100,000 EU.

  4. 4

    Power MV tools and machines

    Insert the charged Energy Crystal into the internal slot of a Diamond Drill, Chainsaw, or another MV-tier IC2 tool to run it far longer than with an RE-Battery.

  5. 5

    Upgrade to Lapotron Crystal

    Use a charged Energy Crystal as the core ingredient when crafting a Lapotron Crystal to step up from MV to HV storage (1,000,000 EU).

Tip

Energy Crystal only delivers MV power; pairing it with LV-only machines requires a transformer to avoid burning out the receiving machine.

Frequently asked questions

How much energy can Energy Crystal store?

Energy Crystal stores up to 100,000 EU and discharges at the MV tier with a maximum output of 128 EU/t.

What is the crafting recipe for Energy Crystal?

Energy Crystal is crafted on a vanilla Crafting Table from 1 Diamond placed in the center surrounded by 8 Redstone Dust.

How do I charge an Energy Crystal?

Place Energy Crystal in the charge slot of an MFE Unit or MFSU, or drop Energy Crystal into the personal charge slot of an MFE/MFSU while wearing it.

Can Energy Crystal power LV machines directly?

Energy Crystal outputs at MV, so LV machines need an MV Transformer in front of them; connecting an MV source to an LV-only machine destroys the machine.

How does Energy Crystal compare to RE-Battery and Lapotron Crystal?

RE-Battery is LV with 10,000 EU, Energy Crystal is MV with 100,000 EU, and Lapotron Crystal is HV with 1,000,000 EU, using Energy Crystal as its core ingredient.
