Copper Battery Block

Inspired by early trial chamber concept art, this block has both a neutral and charged state, indicated by a row of blue lights.

The purpose of this block acts as a translator between electrum, redstone, sound, and wind power, able to interact and power various devices, and be charged by them as well.

When powered, the battery in the block enters charge mode, and when powering, it slowly drains, acting like a limited power source.
