A fire suppression system for use with lithium-ion battery storage containers is provided. The system utilizes water as a fire suppressant, which is stored in a tank and delivered to a battery module within the container that is experiencing a thermal event. After a predetermined time from the beginning of water flow, a controller within the system actuates one or more fans to ventilate the storage container to expel hazardous gases produced by the thermal event.
