Legion C20

20 Foot BESS Container

3.06 MWh

Key Features

Patented Immersion Cooling

Battery cells are submerged in non-toxic
dielectric oil for direct active thermal
management, fire suppression, and
propagation prevention.

Active Thermal Management

Our Battery Management System
(BMS) monitors temperature and
responds with liquid cooling
circulation, enhancing heat exchange.

Integrated BMS & EMS

Our non-Chinese BMS and EMS ensure
optimal performance, safety, and
efficiency, offering unmatched
reliability and control.

Enhanced Durability

Our cabinet is rated at IP54,
ensuring reliable performance in
demanding environments.

1.OS may automatically derate power as necessary to maintain proper cell temperatures.

2.Test ambient temperature at 25 C.

3.The end-of-life (EOL) of a Battery Energy Storage System (BESS) is influenced by its age, usage
application, and environmental temperature, which may result in an actual lifespan of less than 20 years.
