VICTRON ENERGY ● BATTERYPROTECT SERIES Victron BatteryProtect 65A 12V/24V Automatic Battery Over-Discharge & Over-Voltage Protection | Model: BP-65 (VE-BPR65) The Victron BatteryProtect 65A is an essential device for safeguarding your 12V or 24V battery systems from damaging deep discharge and over-voltage conditions. Designed for reliability and ease of use, this intelligent protector automatically disconnects non-essential loads when battery voltage drops too low, preserving battery health and extending its lifespan. It also protects sensitive equipment by disconnecting loads if the battery voltage rises too high. Ideal for a wide range of applications, from off-grid solar setups to marine and automotive systems, the BP-65 ensures your batteries remain within safe operating parameters. Its ultra-low current consumption means it won't drain your battery further, even when disconnected. CRITICAL PROTECTION: Prevents irreversible battery damage from deep discharge and protects loads from over-voltage. Key Features ▶ Low Voltage Disconnect — Automatically disconnects loads to prevent deep battery discharge. ▶ Overvoltage Protection — Safeguards connected appliances from high battery voltage spikes. ▶ Automatic System Detection — Intelligently recognises 12V or 24V systems for straightforward setup. ▶ Programmable Thresholds — Customise disconnect and reconnect voltage levels to suit specific battery types and applications. ▶ Ultra-Low Current Draw — Minimises parasitic drain on the battery, especially during disconnect. ▶ Lithium Battery Compatibility — Features dedicated modes for use with Victron Ve.Bus BMS and as a charge interrupter. ▶ Remote Control & Alarm — Allows for external switching and integration with alarm systems.

Overvoltage Disconnect Protects sensitive equipment by disconnecting loads if battery voltage exceeds a safe upper limit. Programmable Delay Adjustable delay before disconnect/reconnect actions to prevent nuisance tripping from temporary voltage fluctuations. Lithium Mode (Li-ion) Specialised settings for use with Victron Ve.Bus BMS, enabling it to function as a charge interrupter or load disconnect. Automatic Reset Automatically reconnects loads once the battery voltage recovers above the set threshold after a low voltage disconnect. Typical Applications Application Description Off-Grid Solar Systems Protects deep cycle batteries from over-discharge in remote power setups, extending their operational life. Motorhomes & Caravans Ensures leisure batteries are not drained excessively, preserving their health and readiness for use. Marine Vessels Safeguards service batteries on boats from damaging discharge, crucial for reliable onboard power. Automotive Auxiliary Systems Protects secondary batteries powering accessories in vehicles from being drained by non-essential loads. Backup Power Solutions Maintains battery health in standby power applications, ensuring readiness for emergency use. Built-In Protection Functions The Victron BatteryProtect 65A incorporates robust protection features including automatic low voltage disconnect to prevent deep discharge • overvoltage disconnect to shield sensitive loads from high voltage spikes • short-circuit protection for enhanced safety • and a programmable delay for disconnect and reconnect actions, which enhances system stability by preventing nuisance tripping from temporary voltage fluctuations. Common Questions What is the primary function of the Victron BatteryProtect 65A? It protects 12V or 24V batteries from deep discharge and connected loads from over-voltage, extending battery lifespan and safeguarding equipment. Can the BatteryProtect be used with Lithium batteries? Yes, it has specific modes for use with Victron Ve.Bus Lithium battery management systems, functioning as a charge interrupter or load disconnect. How does the BatteryProtect handle system voltage? It automatically detects whether the system is 12V or 24V upon startup, simplifying installation and configuration. Where should the BatteryProtect be installed? It should be connected on the positive battery wire, close to the battery. It is designed for one-directional current flow and generally should not be installed between the battery and a battery charger, except in specialised systems as detailed in the manual. Installation Notes Always refer to the detailed Victron user manual for complete installation instructions and safety guidelines. Ensure the BatteryProtect is installed on the positive battery wire, as close to the battery as possible. Verify correct wiring polarity before applying power to avoid damage to the unit or system. Consider the maximum continuous current rating (65A) and peak current (250A) to ensure it matches your load requirements. The unit is suitable for one-directional current flow; consult the manual for specific system configurations. Before You Buy Confirm your system's nominal voltage (12V or 24V) and ensure it falls within the BatteryProtect's operating range. Check the maximum continuous current draw of your loads to ensure it does not exceed the 65A rating of this model. If using with Lithium batteries, verify compatibility with your specific Battery Management System (BMS), especially Victron Ve.Bus systems. Plan for appropriate cable sizing and fusing in your installation to meet safety standards. Review the product datasheet and manual for detailed technical specifications and installation requirements. Please verify all specifications and compatibility requirements with your specific system before purchase. This product is covered by a 5-year manufacturer warranty.
