Batteries

Batteries are a power item in Astroneer that store power. Batteries will fill when there is a surplus of energy and will drain when power production is low or has stopped.

Batteries have their own input and output speed limits depending on their size; Small Batteries can absorb or release power at 1U/s, which for reference is approximately one bar on a Small Battery every four seconds. Medium Batteries behave like three Small Batteries, at 3U/s, and store and release energy three times as quickly.
