Li-ion Mode Enables control by a VE.Bus Battery Management System (BMS) for enhanced lithium battery protection, including use as a charge interrupter. Delayed Disconnect/Reconnect Features a 90-second load disconnect delay (immediate with VE.Bus BMS) and a 30-second reconnect delay to prevent nuisance trips. System On/Off Switch Can be used as a remote on/off switch for your DC system. Typical Applications Application Description Off-Grid Solar Systems Protects deep cycle batteries from excessive discharge in remote power setups. Marine & RV Ensures critical loads remain powered and prevents starting battery drain in vehicles and boats. Automotive & Commercial Vehicles Safeguards auxiliary batteries and sensitive electronics in vans, trucks, and utility vehicles. Backup Power Systems Maintains battery health in emergency power setups for homes or small businesses. Built-In Protection Functions The Victron Smart BatteryProtect 100A incorporates several safety features for reliable operation: Low Voltage Disconnect • Overvoltage Disconnect • Short Circuit Protection • Delayed Alarm Output (12 seconds) • Delayed Load Disconnect (90 seconds, immediate with VE.Bus BMS) • Delayed Reconnect (30 seconds) • Ignition Proof Design (MOSFETs, no sparks) • Reverse Polarity Protection (internal). These features ensure the longevity of your battery and the safety of your connected equipment. Common Questions What is the primary purpose of the Smart BatteryProtect? Its main function is to prevent batteries from being excessively discharged, which can cause irreversible damage. It disconnects non-essential loads when the battery voltage drops below a safe level. Can I use this with Lithium-ion batteries? Yes, the Smart BatteryProtect has a dedicated Li-ion mode that allows it to be controlled by a Victron VE.Bus Battery Management System (BMS) for optimal protection and can also act as a charge interrupter. Is the Smart BatteryProtect a bi-directional device? No, it is a uni-directional device. It is designed to handle current flow in one direction only, typically from the battery (IN terminal) to the load (OUT terminal), or from a charger (IN terminal) to the battery. It is not designed for simultaneous charge and discharge currents. How do I program the voltage settings? The Smart BatteryProtect can be easily programmed via Bluetooth using the VictronConnect app on your smartphone or tablet. Alternatively, specific settings can be selected using the programming pin. Installation Notes Install in a well-ventilated area, preferably close to the battery (max 50cm). Avoid installing directly above the battery due to potential corrosive gases. Ensure correct cable sizing and length to prevent voltage drop and ensure optimal performance. A properly sized fuse must be installed in the cable between the battery and the SBP according to local regulations. Connect on the positive battery wire. Before You Buy Verify your system voltage (12V or 24V) and ensure it matches the product's capabilities. Confirm the maximum continuous current draw of your loads does not exceed 100A. Understand that this is a uni-directional device; it handles current in one direction only. Review the user manual for detailed wiring diagrams and programming instructions. Consider if an external BMS is required for advanced lithium battery management. Always consult the manufacturer's manual for specific installation guidelines and compatibility details. Specifications are subject to change. This product is covered by a 5-year manufacturer warranty.
