Victron Energy Smart BatteryProtect – 12/24V Auto Ranging
Safeguard Your Battery from Over-Discharge and Over-Voltage
The Victron Smart BatteryProtect is designed to disconnect non-essential loads from your battery before it becomes overly discharged—preventing damage and preserving battery life. It also ensures enough power is retained to crank your engine when needed. With Bluetooth-enabled configuration and smart features, it's a critical component in any advanced DC electrical system.
Key Features:
-
Automatic Voltage Detection
Supports both 12V and 24V systems with automatic voltage recognition during initial setup. -
Bluetooth Programming
Easily set custom engage/disengage voltage thresholds or choose from nine predefined levels using the VictronConnect App or programming pin. -
Real-Time Status Readout
View alarms, warnings, and device status at a glance through the VictronConnect Device List—even without pairing. -
Ideal for Lithium Batteries
Features a dedicated setting for use with Li-ion systems and compatibility with VE.Bus BMS for controlled charge/discharge. -
Ultra-Low Standby Power Consumption
Critical for lithium battery banks, especially after low-voltage cut-off conditions. -
Over-Voltage Protection
Automatically disconnects the load when voltage exceeds safe limits (16.3V or 32.6V), protecting sensitive electronics. -
MOSFET-Based Switching
Spark-free, ignition-proof operation thanks to solid-state design—no relays, no arcing. -
Delayed Load Disconnect & Reconnect
Prevents nuisance cut-offs:
• Disconnects 90 seconds after voltage drops below threshold
• Reconnects 30 seconds after voltage rises above threshold -
Programmable Alarm Output
Sends a signal after 12 seconds of undervoltage to activate LEDs, buzzers, or relays (max 50 mA open collector).
Installation Notes:
-
Unidirectional Current Flow
Current flows from IN → OUT only. For load protection, connect the battery to the IN terminal. For charger protection, connect the charger to IN. -
Use as a Charge Interrupter
Can be installed between a charger and a Li-ion battery to stop charging when needed (see manual for diagram).
Recommended For:
✔️ RVs, marine, solar systems
✔️ Lithium and AGM battery banks
✔️ Vehicle systems needing programmable low-voltage protection
