What is depth of discharge? | EnergySage

It''s generally not recommended to discharge your battery entirely, as doing so could harm the system. To protect against this, many manufacturers specify a maximum depth of discharge, or DoD, which measures the amount of electricity you can safely pull from the battery without damaging it, relative to its overall capacity.. For example, if a 10 kWh battery has a
