Advanced 12V battery management system with built-in 200A MOSFET load disconnect, Bluetooth, and full VE.Bus integration for larger lithium installations.
The Victron Smart BMS 12/200 is a full-featured BMS for 12V lithium systems that need high-current load disconnect without external contactors. Its internal 200A MOSFET handles load interruption directly, simplifying wiring and reducing the component count in the battery compartment. A separate pre-charge relay output manages the charge disconnect path for safe, coordinated system shutdown and restart.
Bluetooth connectivity provides real-time status monitoring through the VictronConnect app, while VE.Bus and VE.Direct interfaces enable deep integration with MultiPlus/Quattro inverter/chargers and GX monitoring devices. Active cell balancing via Smart Battery Sense ensures cells stay matched over time, extending pack life and maintaining consistent capacity. Programmable voltage thresholds give system designers precise control over disconnect and reconnect points.
Used in Alchemy industrial power systems for 12V lithium battery management in surveillance trailers, mobile signage platforms, and field-deployed autonomous systems requiring reliable automated battery protection.
