Victron Smart Battery Protect 48V-100A - BPR110048000

Overview

The Victron Smart BatteryProtect is an intelligent battery protection device designed to disconnect non-essential loads before a battery becomes excessively discharged. This protects the battery from permanent damage and ensures sufficient reserve power remains available for critical loads or engine starting.

With built-in Bluetooth for simple programming, advanced delay logic, and dedicated lithium battery support, the Smart BatteryProtect is ideal for automotive, marine, RV, and off-grid power systems using either lead-acid or lithium batteries.

Key Features

Battery Protection & System Control

• Disconnects non-essential loads before harmful deep discharge
• Can be used as a system-wide on/off switch via remote input
• Uni-directional device for load or charger interruption

Bluetooth Programming & Flexibility

• Set custom engage and disengage voltages via Bluetooth
• Nine predefined voltage profiles selectable via programming pin
• Bluetooth can be disabled if required

Lithium Battery Compatibility

• Dedicated Li-ion mode controlled by VE.Bus BMS
• Can be used as a charge interrupter between charger and lithium battery
• Optimised for lithium systems with ultra-low standby consumption

Advanced Safety & Protection

• Over-voltage protection disconnects load above 16.3 V (12 V) or 32.6 V (24 V)
• Ignition-proof MOSFET switching – no relays or sparks
• Automatic voltage detection for 12 V / 24 V systems

Delayed Alarm & Load Control

• Alarm output activates after 12 seconds below disconnect voltage
• 90-second delayed load disconnect prevents nuisance trips
• 30-second delayed reconnect after voltage recovery
• Short-circuit-proof alarm output (max 50 mA)
