Its seven-segment display makes setup straightforward, allowing users to select from multiple engage/disengage voltage settings. For Li-ion batteries, a dedicated mode enables external control via a VE.Bus Battery Management System (BMS), ensuring precise protection tailored to lithium chemistry. In this mode, the BatteryProtect acts as a remotely controlled disconnect switch, responding directly to BMS commands. The device also incorporates a delayed alarm output, which activates if the battery voltage remains below the preset disconnect level for more than 12 seconds, preventing nuisance alarms from temporary voltage dips, such as during engine starting. Load disconnection is similarly delayed by 90 seconds, providing a window for voltage recovery before critical loads are shed. Typical Applications Leisure Vehicles Ideal for caravans, motorhomes, and campervans to protect auxiliary batteries. Marine Systems Ensures boat batteries are protected from over-discharge, preserving power for engine starting and critical electronics. Off-Grid Solar Safeguards battery banks in remote solar installations by disconnecting non-essential loads. Backup Power Systems Maintains battery health in backup power setups, ensuring readiness for outages. Built-In Protection Functions The Victron Battery Protect BPR000100400 incorporates several safety features to ensure reliable operation and system longevity. These include: Over-Voltage Protection, which disconnects loads if DC voltage exceeds safe limits (16V for 12V systems, 32V for 24V systems) • An Ignition-Proof Design utilising MOSFET switches to prevent sparks, making it safe for environments with fuel vapours • Short-Circuit Protection, which attempts to reconnect the load after 5 seconds if a short circuit is detected, displaying an E1 error after two attempts • Over-Temperature Protection, safeguarding the unit from internal overheating. Common Questions What is the primary function of the Victron Battery Protect? Its main function is to prevent deep discharge of your battery by automatically disconnecting non-essential loads when the battery voltage falls below a programmable threshold. This protects the battery from damage and prolongs its lifespan. Can this Battery Protect be used with lithium (Li-ion) batteries? Yes, it has a special Li-ion mode that allows it to be controlled by a Victron VE.Bus BMS. This ensures optimal protection for lithium battery systems. Is the Victron BPR000100400 suitable for both 12V and 24V systems? Yes, this model features 12/24V auto-ranging, meaning it automatically detects and adapts to either a 12V or 24V system voltage. What does "ignition proof" mean for this device? The Battery Protect uses MOSFET switches instead of mechanical relays. This solid-state switching eliminates the risk of sparks during operation, making it safe for installation in environments where flammable vapours might be present, such as engine compartments. Installation Notes Install the Battery Protect in a well-ventilated area, preferably close to the battery (within 50 cm). Ensure a properly sized fuse is installed in the cable between the battery and the Battery Protect, according to local regulations. The Battery Protect is a uni-directional device; ensure current flows from the battery (IN terminal) to the load (OUT terminal) or from a charger (IN terminal) to the battery. It cannot handle both simultaneously. Do not connect the load output until the Battery Protect has been fully programmed. For Li-ion mode, connect the load disconnect output of your BMS to the remote H terminal of the Battery Protect. Before You Buy Verify the maximum continuous load current of your system does not exceed 100A. Confirm your battery system voltage is either 12V or 24V. If using Li-ion batteries, ensure your BMS has a load disconnect output for optimal integration with the Battery Protect's Li-ion mode. Note that this specific model (BPR000100400) does not have built-in Bluetooth connectivity. Consider the physical dimensions (H59 x W42 x D115mm) to ensure adequate mounting space.
