Victron Energy BatteryProtect 12/24V-100A – Smart Load Disconnect for Battery Protection

Protect your battery from deep discharge and preserve starting power with the Victron BatteryProtect 12/24V-100A. This compact, uni-directional load disconnect unit automatically shuts off non-essential loads when voltage drops too low—extending battery life and ensuring your system stays operational when you need it most.

Key Features:

• 12/24V Auto-Ranging Detection
  Automatically detects system voltage, simplifying installation in mixed-voltage setups.
• Programmable Disconnect/Reconnect Levels
  Easily set custom engage/disengage thresholds using the built-in 7-segment display—no external tools required.
• Li-ion Battery Compatible
  Includes a special mode for use with the VE.Bus BMS, enabling safe integration into lithium-based systems. Also usable as a charge interrupter between charger and battery.
• Ultra-Low Power Consumption
  Ideal for Li-ion systems, especially after low-voltage shutdown events.
• Overvoltage Protection
  Automatically disconnects loads if voltage exceeds 16V (12V systems) or 32V (24V systems), protecting sensitive electronics.
• MOSFET-Based Ignition-Proof Design
  Spark-free operation ensures safe use in volatile environments—no mechanical relays required.
• Delayed Load Disconnect & Reconnect
  Prevents unnecessary cutoffs during engine cranking. Load disconnect is delayed by 90 seconds; reconnect occurs 30 seconds after voltage recovery.
• Alarm Output
  Short-circuit-proof open collector output (50mA max) activates after 12 seconds of undervoltage—ideal for triggering alerts via buzzers, LEDs, or relays.

Applications:

Marine, RV, off-grid, and backup systems where battery protection and automated load control are critical.
