Victron Energy ▶ Battery Protection Victron BatteryProtect 100A 12V/24V Battery Over-Discharge & Over-Voltage Protector | Model BP-100 (VE-BPR100) The Victron BatteryProtect 100A is an essential device designed to safeguard your 12V or 24V battery systems from damaging deep discharge and over-voltage conditions. This intelligent protector automatically disconnects non-essential loads when battery voltage drops below a user-defined threshold, preserving battery health and extending its lifespan. With its robust 100A continuous current rating and automatic system voltage detection, the BP-100 provides reliable protection for a wide range of DC applications. It also features over-voltage protection to shield sensitive equipment from potential damage due to voltage spikes. CRITICAL PROTECTION: Safeguards 12V/24V battery systems from damaging deep discharge and over-voltage, ensuring longevity and reliability. Key Features ▶ Low Voltage Disconnect — Prevents deep discharge to protect battery health. ▶ Over-Voltage Protection — Disconnects loads to shield sensitive equipment from high voltage. ▶ Automatic 12V/24V Detection — Simplifies installation with auto-ranging system voltage recognition. ▶ Programmable Thresholds — Customise disconnect and reconnect voltages for specific battery types or needs. ▶ Ultra-Low Current Consumption — Minimises parasitic drain on the battery, especially after shutdown. ▶ Li-ion Battery Compatibility — Specialised mode for external BMS control (e.g., Victron VE.Bus BMS) for load or charge interruption. ▶ Remote Control & Alarm Output — Allows for external switching and integration with alarm systems. Technical Specifications Parameter Value Nominal Battery Voltage: 12V / 24V (Auto Detect) Operating Voltage Range: 6 - 35V DC Max. Continuous Current: 100A Peak Current (30 seconds): 600A Current Draw (Active): <1.5mA Current Draw (Disconnected): <0.6mA Alarm Relay Max. Current: 50mA Operating Temperature: -40°C to +40°C Dimensions (H x W x D): 59 x 42 x 115 mm Weight: 500g Operating & Protection Modes The Victron BatteryProtect offers flexible operating modes to suit various battery chemistries and system requirements. It features user-programmable voltage thresholds for both low-voltage disconnect and reconnect, indicated via a seven-segment display for easy setup. Mode/Feature Description Standard Disconnect Disconnects loads after a 90-second delay when battery voltage falls below the set threshold, preventing false triggers. Li-ion Mode (Mode C) Enables external control by a Victron VE.Bus BMS or other compatible BMS for immediate load or charge disconnection. Delayed Reconnect Automatically reconnects loads 30 seconds after the battery voltage rises above the set reconnect threshold. Alarm Output Activates an alarm output (e.g., for a buzzer or LED) if battery voltage drops below the threshold for more than 12 seconds. Typical Applications Application Description Off-Grid Solar Systems Protects batteries in cabins, sheds, and remote installations from excessive discharge. Marine & RV Power Ensures leisure batteries are not drained beyond recovery, preserving power for essential services. Backup Power Systems Maintains sufficient charge in backup batteries to ensure readiness for power outages. Small Commercial Vehicles Protects auxiliary batteries powering tools, lighting, or communication equipment. Built-In Protection Functions The Victron BatteryProtect 100A incorporates several safety features to ensure reliable operation and system longevity. These include: Low Voltage Disconnect to prevent irreversible battery damage • Over-Voltage Disconnect to protect connected loads from high voltage spikes (e.g., 16.3V for 12V systems, 32.6V for 24V systems) • Ignition Proof Design utilising MOSFET switches instead of mechanical relays, eliminating sparks for enhanced safety • Short Circuit Proof Alarm Output for external signalling. Common Questions What is the primary function of the Victron BatteryProtect 100A? Its primary function is to protect 12V or 24V batteries from excessive discharge and over-voltage. It disconnects non-essential loads when the battery voltage falls too low or rises too high, preserving battery life and protecting connected equipment. Can this BatteryProtect be used with Lithium-ion batteries? Yes, it has a dedicated Li-ion mode (Mode C) that allows it to be controlled by an external Battery Management System (BMS), such as a Victron VE.Bus BMS, for precise load or charge disconnection. Is the BatteryProtect suitable for use with inverters? No, the BatteryProtect is a unidirectional device designed for DC loads only and is not compatible with inverters. Inverters have large input capacitors that can trigger the unit's short circuit protection upon connection. How does it handle temporary voltage drops, such as engine starting? It features a delayed alarm output (12 seconds) and a delayed load disconnect (90 seconds). This prevents the BatteryProtect from reacting to short, temporary voltage drops, such as those caused by engine cranking. Installation Notes Connect the BatteryProtect on the positive battery wire, as close to the battery as possible. Ensure the device is installed in a dry, protected environment within its specified operating temperature range. This product is suitable for one-directional current flow only. Do not install it between a battery and a battery charger, except in specialised Li-ion systems with a compatible BMS for charge interruption. Refer to the detailed user manual for comprehensive wiring diagrams and programming instructions. Before You Buy Verify your system voltage (12V or 24V) and ensure the continuous current draw of your loads does not exceed 100A. Confirm that this unidirectional device meets your system's current flow requirements. If using with Lithium-ion batteries, ensure you have a compatible external BMS if you intend to use the dedicated Li-ion mode. Consider the physical dimensions (59 x 42 x 115 mm) for your intended installation location. Please verify all specifications and compatibility requirements for your specific application before purchase. This product is covered by a 5-year manufacturer warranty.
