The Lapotron Crystal can store one million (1,000,000) EU. The light on the Lapotron Crystal changes from red to yellow then green once fully charged. It is created with Lapis Lazuli, an energy crystal, and electronic circuits. A MK3 Charging Bench and MFSU are capable of charging and discharging the power of the crystal, and an HV Solar Array can charge them.
Lapotron Crystals are required to craft the following:
Note: The energy crystal does not have to be charged, but upon crafting with a charged or partially charged energy crystal the EU will pass on to the Lapotron crystal, in most cases. EU charge will also pass on from a Lapotron or Energy crystal to any items crafted from them that can hold EU.
