At this point, it''s worth noting depth of discharge. This refers to the amount of battery capacity you can use safely. For example, if a 12kWh battery has an 80% depth of discharge, this means you can safely use 9.6kWh. You should never use your battery beyond its depth of discharge as this can cause permanent damage.
