The battery holds up to 10000 energy for use by devices connected to the same device network.
Batteries are modular - adjacent batteries connect to each other and can share a single power connection. Smaller ships can run entirely on batteries, but most ships use them as a buffer to handle periods of higher energy use without wasting Generator output.
