Victron BatteryProtect BP-100 100 A protects 12/24 V battery systems from deep discharge and overvoltage, extending battery life and safeguarding connected loads.

• Low-voltage disconnect: automatically disconnects loads when battery voltage falls below a programmable threshold to prevent deep discharge.
• Programmable low-voltage threshold: customise disconnect and reconnect voltages for different battery chemistries, including dedicated VE.Bus Lithium settings.
• Overvoltage load disconnect: disconnects loads if battery voltage exceeds a set limit to protect appliances and equipment.
• Automatic system recognition: detects nominal system voltage (12 V or 24 V) at start-up for simple installation and setup.
• Ultra-low current consumption: <1.5 mA during active operation and <0.6 mA when disconnected to minimise battery drain.
• Remote switch and alarm connections: dry-contact inputs and an alarm relay allow remote control and status signalling.
• Compatible with lithium and lead-acid batteries: includes specialised modes for VE.Bus Lithium battery management and support for VE.Bus BMS mode.
• Easy to program: adjustable settings for different battery types and application requirements; consult the manual for programming details.
• Nominal battery voltage: 12/24 V.
• Operating voltage range: 6–35 V.
• Maximum continuous current: 100 A.
• Peak current: 600 A (30 s).
• Current draw: <1.5 mA active; <0.6 mA during disconnect.
• Alarm relay: 50 mA.
