xVictron Smart BatteryProtect 48V-100A — BPR110048000
The Victron Smart BatteryProtect 48V-100A is an intelligent load disconnect device designed to protect 48V battery banks from over-discharge and over-voltage damage. It is aimed at off-grid installers, marine electricians and commercial system integrators who need reliable, programmable battery protection without relying on a full battery management system to handle load shedding.
Key Features
- Rated for 48V battery systems with a continuous load current of 100A, suitable for substantial DC load circuits.
- Bluetooth connectivity via the VictronConnect app allows wireless configuration, threshold adjustment and real-time monitoring from a smartphone or tablet.
- Programmable low-voltage disconnect and reconnect thresholds to suit different battery chemistries including lead-acid, AGM, gel and lithium.
- High-voltage (over-voltage) disconnect function protects sensitive loads from voltage spikes during charging.
- Algorithm-based reconnect logic prevents rapid cycling: the device waits for the battery to recover to the set reconnect voltage before restoring the load.
- Remote on/off input allows integration with external control signals, including Victron system components.
- No-load current draw is extremely low, making it suitable for installations where parasitic drain must be minimised.
- Compact and lightweight at 0.8 kg, with straightforward wiring for inline DC load protection.
Product Overview
The Smart BatteryProtect monitors battery voltage continuously and disconnects the load circuit when voltage drops below the programmed threshold. This prevents deep discharge events that shorten battery life, particularly in lead-acid chemistries where repeated deep cycling causes irreversible capacity loss. For lithium batteries, it provides a secondary hardware-level protection layer alongside the battery's own BMS.
The Bluetooth interface sets this unit apart from basic analogue battery protects. Using VictronConnect, an installer can configure all thresholds, select a preset algorithm for common battery types, and view the current status without needing a display panel or physical DIP switches. This is particularly useful in enclosed or hard-to-access installations such as under-floor battery compartments, marine bilge areas or cabinet-mounted off-grid systems.
The over-voltage disconnect function is relevant in systems where the charger or solar charge controller could, under fault conditions, push voltage above safe limits for connected loads. The Smart BatteryProtect will open the load circuit in response, protecting inverters, converters and other DC equipment downstream.

Applications
- Off-grid solar systems where DC loads must be disconnected before the battery bank reaches damaging discharge levels.
- Marine and narrowboat installations requiring automatic load shedding to protect the house battery bank.
- Motorhome and campervan builds with 48V lithium or lead-acid leisure battery systems.
- Telecom and remote monitoring installations where battery longevity is critical and site visits are infrequent.
- Commercial cabinet systems where Bluetooth configuration removes the need for physical access during commissioning.
What Is Included
- 1 x Victron Smart BatteryProtect 48V-100A (BPR110048000)
Installation Notes
The Smart BatteryProtect must be installed in the load circuit only, between the battery and the DC loads. It is not designed to interrupt charging current and must never be placed in series with a charger output. For 48V lithium battery systems, installation should be carried out by a qualified electrician familiar with high-voltage DC systems. Ensure all cabling is rated for the full 100A continuous current and that appropriate fusing is fitted on the battery side of the unit in accordance with wiring regulations. Configuration via VictronConnect requires a compatible Bluetooth-enabled device running the VictronConnect app.
