Common Questions What does a BatteryProtect do? A BatteryProtect prevents damage to your battery by disconnecting non-essential loads when the battery voltage drops below a safe level (low voltage disconnect) or rises too high (over-voltage disconnect). This protects both the battery and connected appliances. Is the Victron BatteryProtect compatible with Lithium batteries? Yes, the Victron BatteryProtect 220A is compatible with Lithium batteries. It features specialised modes that allow it to function as a charge interrupter when used with a Victron Ve.Bus Lithium Battery Management System (BMS). Can I use the BatteryProtect between a battery and a charger? Generally, the BatteryProtect should not be installed between a battery and a battery charger, as it is designed for one-directional current flow (from battery to load). However, it can be used in specialised systems, such as a charge interrupter for Lithium batteries when controlled by a BMS. Always refer to the detailed user manual for specific wiring diagrams and recommendations. How do I program the low-voltage disconnect settings? The Victron BatteryProtect 220A features programmable low-voltage thresholds. Programming is typically done via a simple setup procedure using a dedicated pin or button sequence, as detailed in the comprehensive user manual supplied with the unit. Installation Notes Connect the BatteryProtect on the positive battery wire. Install the unit as close to the battery as practically possible. Ensure correct polarity during installation to avoid damage. This device is designed for one-directional current flow. Refer to the detailed user manual for complete wiring diagrams and safety instructions. Before You Buy Verify your system voltage (12V or 24V) matches the product's capabilities. Confirm the maximum continuous current of your loads does not exceed 220A. Consider the peak current requirements of your system (up to 600A for 30 seconds). Review the user manual for detailed compatibility with your specific battery type and system configuration. Professional installation is recommended for complex systems. Please verify all specifications and compatibility requirements with your specific system before purchase. Product specifications are subject to change by the manufacturer. This product is typically covered by a manufacturer's warranty.
