Victron Energy Smart BatteryProtect 12/24V 65A (Bluetooth) — auto low-voltage disconnect, 250A peak

Victron Energy Smart BatteryProtect 12/24-Volt 65 amp with Bluetooth is an inline battery disconnect that protects batteries from deep discharge and preserves starting power by automatically switching off non-essential loads.

This compact, auto-ranging device monitors system voltage and disconnects auxiliary circuits before a battery becomes dangerously depleted. Built-in Bluetooth lets you view and change engage/disengage thresholds from a phone or tablet, or choose one of nine preset levels. With a continuous rating of 65 A and a 30-second peak capacity of 250 A, the unit is suited for boats, RVs, small off-grid systems and vehicle accessory circuits where preserving starter battery capacity matters.

How does the BatteryProtect stop a battery from being over-discharged?

The unit continuously monitors battery voltage and cuts power to defined non-essential loads when voltage falls below your configured threshold. It prevents permanent battery damage and ensures there is enough charge left for engine starting or essential electronics.

• Automatic low-voltage disconnect based on configured engage/disengage levels
• Selectable presets or custom thresholds via Bluetooth
• Restores connection automatically or after a defined timeout once voltage recovers

What settings and controls are available with Bluetooth?

Bluetooth provides a simple interface to read real-time voltage, change disconnect/reconnect points, and enable or disable features without removing covers or using DIP switches. If preferred, Bluetooth can be turned off for a set-and-forget installation.

• Set custom engage and disengage voltages from your smartphone
• Choose from nine predefined voltage levels if you want quick configuration
• Turn Bluetooth off for maximum device security and simplicity

Which systems and currents is this model designed for?

The Smart BatteryProtect automatically detects whether it’s in a 12 V or 24 V system during initial power-up, then protects loads accordingly. It handles continuous currents up to 65 A with a robust 250 A peak for short durations like motor starts or inrush currents.

• 12/24 V auto-detection at first power-up—no manual jumper needed
• Continuous current rating: 65 A, 30-second peak current: 250 A
• Ideal for accessory loads, inverters of modest size, fridges, lighting and electronics

How should I install and maintain the BatteryProtect?

Correct installation is important for safe operation. The device should be wired between the battery and the loads to be protected, with appropriate cable sizing, fusing and adherence to local electrical codes. When in doubt consult a licensed electrician or marine technician.

• Wire in series with the loads you want to protect; follow Victron wiring guidance
• Use appropriately sized cable and fuses for 65 A continuous loads and higher peaks
• Check firmware/config settings via Bluetooth after installation and periodically inspect wiring

Who is this for? The Victron Energy Smart BatteryProtect 12/24-Volt 65 amp with Bluetooth is aimed at boat owners, RV and camper van builders, off-grid hobbyists and vehicle integrators who need reliable, configurable protection for auxiliary batteries and accessory circuits. It fits installations where preventing deep discharge, preserving starter capacity and having remote configuration or diagnostics via Bluetooth are priorities. Installers and owners seeking a compact, easy-to-configure inline protector with strong short-term current capability will find this model well-matched to small-to-medium DC systems.
