Victron Smart BatteryProtect 65A 12V/24V
Battery Over-Discharge & Over-Voltage Protector | SBP-65 with Bluetooth
The Victron Smart BatteryProtect 65A (SBP-65) is an essential device for safeguarding your 12V or 24V battery systems from damaging deep discharge and over-voltage conditions. This intelligent battery protector automatically disconnects non-essential loads when battery voltage drops too low, preserving battery health and extending its lifespan. It also protects sensitive appliances from potential damage caused by excessive voltage.
Featuring integrated Bluetooth connectivity, the SBP-65 allows for easy monitoring and customisation of voltage settings directly from your smartphone via the VictronConnect app. Its automatic system recognition simplifies installation, making it a reliable choice for a wide range of applications, including off-grid solar, marine, and vehicle power systems.
CRITICAL PROTECTION: Safeguards 12V/24V battery systems against damaging deep discharge and over-voltage conditions, enhancing longevity and reliability.

Battery Protection & Control
The Victron Smart BatteryProtect 65A offers versatile control over your battery system's discharge and charge cycles. It features programmable low-voltage disconnect thresholds, allowing you to customise the point at which non-essential loads are disconnected to suit your specific battery type and usage patterns.
For Lithium battery systems, the SBP-65 includes specialised modes that enable external control from a Battery Management System (BMS), such as the Victron VE.Bus BMS. This allows it to function effectively as a load disconnect or even a charge interrupter in compatible setups, providing comprehensive protection.
The device is designed for one-directional current flow, typically installed between the battery and the loads. Its remote switch and alarm connections provide additional flexibility for system integration, enabling manual control and triggering external alarm systems based on battery status.
Typical Applications
| Application | Description |
|---|---|
| Off-Grid Solar Systems | Protects batteries in remote power setups from deep discharge, ensuring system reliability. |
| Motorhomes & Caravans | Prevents leisure battery deep discharge, safeguarding power for onboard appliances. |
| Marine Vessels | Safeguards boat service batteries and sensitive marine electronics from voltage fluctuations. |
| Backup Power Systems | Ensures battery readiness for critical loads by preventing excessive discharge during outages. |
Built-In Protection Functions
The Victron Smart BatteryProtect 65A incorporates multiple protection mechanisms to ensure the safety and longevity of your battery system and connected equipment. These include low voltage disconnect to prevent deep discharge • over-voltage disconnect to protect loads from high voltage • short circuit protection with automatic retry attempts • and an ignition-proof design utilising MOSFET switches instead of relays to prevent sparks.
Common Questions
What is the primary function of the Smart BatteryProtect?
Its main purpose is to prevent deep discharge and over-voltage conditions in 12V/24V battery systems, thereby protecting both the battery and any connected loads.
Can I use this with Lithium batteries?
Yes, the Smart BatteryProtect includes specialised modes for use with Victron Ve.Bus Lithium battery management systems, allowing for external control from the BMS.
How do I configure the voltage settings?
The device features built-in Bluetooth, enabling easy programming and monitoring of voltage settings via the VictronConnect smartphone app.
Where should the Smart BatteryProtect be installed?
It should be connected on the positive battery wire, as close to the battery as possible. It is designed for one-directional current flow.
Installation Notes
- Connect the Smart BatteryProtect on the positive battery wire, close to the battery.
- Ensure correct polarity during installation to avoid damage.
- This device is suitable for one-directional current flow only.
- Do not install between a battery and a battery charger, except in specialised Lithium systems as a charge interrupter.
- Refer to the detailed user manual for complete wiring diagrams and instructions.
Before You Buy
- Verify your system voltage (12V or 24V) matches the device's auto-sensing capabilities.
- Confirm the continuous current draw of your loads does not exceed 65A.
- Consider if your application requires bi-directional current flow; this unit is one-directional.
- For Lithium battery applications, ensure compatibility with your specific Battery Management System (BMS).
- Always consult the official Victron Energy documentation for the most up-to-date information.
Always consult the manufacturer's manual for detailed installation, operation, and compatibility information. Specifications are subject to change without prior notice.
