Victron Energy BatteryProtect 48V-100A
Victron Energy BatteryProtect 48V-100A
Smart Load Disconnect for Battery Protection
Prevent deep battery discharge and safeguard critical system power with the Victron Energy BatteryProtect 48V-100A. This advanced device automatically disconnects non-essential loads before your battery is excessively depleted or before voltage drops below engine cranking levels—protecting battery life and system integrity.
Key Features
-
Automatic Load Disconnection
Disconnects loads before battery voltage becomes critically low or when starting power must be preserved. -
Uni-Directional Current Flow
Designed for current flow from Battery → Load only. Cannot manage bidirectional flow—use case must be load OR charger, not both. -
48V System Support
Ideal for 48V systems; also available in other voltage variants. -
Programmable Voltage Thresholds
Easy voltage set-up via seven-segment display. Select from multiple engage/disengage presets for tailored protection. -
Li-ion Battery Mode
Includes dedicated setting for VE.Bus BMS control with lithium batteries. Can also serve as a charge interrupter for LiFePO₄ systems. -
Ultra-Low Standby Power Draw
Critical for lithium batteries post low-voltage shutdown—ensures minimal current consumption during standby. -
Overvoltage Protection
Automatically disconnects the load if system voltage exceeds safe thresholds (e.g., >32V), protecting sensitive devices. -
Ignition-Proof MOSFET Design
Spark-free switching ensures safe use around volatile systems or environments. -
Alarm Output with Delay
Sends warning signal (max 50 mA open collector) if voltage drops below threshold for more than 12 seconds—avoiding false alarms from short dips during engine cranking. -
Delayed Disconnect/Reconnect Logic
- Disconnect delay: 90 seconds post alarm
-
Reconnect delay: 30 seconds after voltage recovery
Prevents unnecessary power cycling during temporary voltage changes.
Ideal For:
Battery-powered DC systems, off-grid installations, lithium and AGM battery protection, marine, RV, and industrial applications.
