Lapotron Crystal Blank is the chargeable half of the HV-tier crystal in Ala Industrial, the tech mod for Minecraft 26.2 Java Edition that runs on both Fabric and NeoForge. The blank is assembled on a plain crafting table: four Advanced Circuits in the corners, three Resonance Coils across the top and sides, a finished Energy Crystal in the center and one Energy Clot II directly below it — nine parts filling the whole 3×3 grid. Once assembled, the shell accepts energy in any charge slot at up to 128 EU per tick (1/20 of a second) and holds up to 500,000 EU. Lapotron Crystal Blank never discharges: no slot drains the stored EU and no tool runs off it, so every EU pushed in is the manufacturing price of the crystal.

When the buffer reaches 500,000 EU, the Lapotron Crystal Blank is replaced in place by a finished Lapotron Crystal — in a Reinforced Energy Storage slot that takes about 3 minutes 15 seconds. The finished Lapotron Crystal is an ordinary crafting material: no charge bar, no buffer, nothing to charge or drain, and in Ala Industrial it currently goes into the Resonant Crystal Blank, the next rung of the ladder. The ladder cannot be skipped, because each blank is built around the finished crystal of the previous rung — 100,000 EU for the Energy Crystal (MV), 500,000 EU for the Lapotron Crystal (HV) and 1,500,000 EU for the Resonant Crystal. A Battery Box slot, a Charging Station under the player's feet, a worn Energy Pack or even another mod's charger fills the Lapotron Crystal Blank equally well.
