# C&I Battery Cabinet High-voltage C&I battery cabinets — parallel operation, liquid or air cooling and integrated fire suppression. The C&I battery cabinet runs on a high-voltage DC architecture, with 100–500 kWh per cabinet and the ability to parallel several cabinets into one string. Each unit carries liquid or air cooling, an actively balancing BMS, Pack-level fire detection and suppression, and dedicated aisles for firefighting and maintenance so it can be installed and serviced inside a working plant.
