Current 50mA Operating Temperature -40°C to +40°C Dimensions (H x W x D) 62 x 123 x 120 mm Weight 800g Terminals M8 Operating & Protection Modes The Victron Smart BatteryProtect 220A is designed for versatile battery management. It operates as a uni-directional device, meaning current flows from the IN terminal to the OUT terminal. This allows it to protect loads from a battery or protect a battery from a charger, but not both simultaneously. For lead-acid batteries, it prevents deep discharge by disconnecting loads at a user-defined low voltage threshold. For lithium batteries, it offers a specialised mode that allows external control from a Victron VE.Bus Battery Management System (BMS), enabling precise protection based on BMS signals. It can also function as a charge interrupter in lithium charging setups. The device features delayed load disconnect and reconnect functions to prevent nuisance tripping, for instance, during engine cranking. An alarm output is also provided, activating if the battery voltage drops below the preset disconnect level for more than 12 seconds. Typical Applications Application Area Description Off-Grid Solar Systems Protects solar battery banks from over-discharge, ensuring longevity and reliable power supply. Motorhomes, Caravans & Boats Safeguards leisure batteries, preventing damage from excessive discharge by onboard appliances. Backup Power Systems Ensures batteries remain healthy for critical loads during power outages. Industrial & Commercial Vehicles Protects vehicle batteries from discharge by auxiliary equipment, ensuring starting power. Built-In Protection Functions The Victron Smart BatteryProtect 220A incorporates several robust protection mechanisms to ensure system safety and battery longevity. These include: Low Voltage Disconnect to prevent deep discharge • Over-Voltage Disconnect to protect sensitive loads from high DC voltage spikes (e.g., above 16.3V for 12V systems or 32.6V for 24V systems) • Ignition Proof Design using MOSFET switches instead of relays, eliminating sparks • Delayed Alarm Output to avoid false alarms during transient voltage drops • Delayed Load Disconnect and Reconnect to prevent unnecessary interruptions. Common Questions What is the primary function of the Victron Smart BatteryProtect 220A? Its main purpose is to protect your 12V or 24V battery from excessive discharge, which can cause irreversible damage, and to protect connected loads from over-voltage conditions. How does the Bluetooth feature work? The integrated Bluetooth allows you to connect your smartphone via the VictronConnect app to easily program custom low-voltage disconnect thresholds, monitor real-time status, and enable/disable features. Can this device be used with Lithium batteries? Yes, the Smart BatteryProtect has a dedicated Li-ion mode, allowing it to be controlled by a Victron VE.Bus BMS for optimal protection and management of lithium battery systems. Is it suitable for both 12V and 24V systems? Yes, the Smart BatteryProtect 220A automatically detects the system voltage (12V or 24V) upon startup, simplifying installation and ensuring correct operation for either system. Installation Notes Connect the Smart BatteryProtect on the positive battery wire, as close to the battery as possible. Ensure the device is installed for one-directional current flow only. It is typically used to protect loads from the battery. Avoid installing it directly between a battery and a battery charger, except in specialised systems as detailed in the user manual. Refer to the detailed user manual for comprehensive wiring diagrams and programming instructions. Professional installation is recommended to ensure correct setup and optimal performance. Before You Buy Verify your battery system voltage (12V or 24V) matches the device's auto-ranging capability. Confirm the maximum continuous current draw of your loads does not exceed 220A. Consider your battery chemistry (lead-acid or lithium) and if a separate BMS is required for lithium systems. Review the Victron Energy datasheet and manual for detailed technical specifications and compatibility. Ensure you have the necessary M8 terminals and appropriate cabling for installation. Always verify product specifications and compatibility with your existing system components before purchase. Victron Energy offers a 5-year manufacturer warranty on this power product.
