Victron Energy smallBMS with Pre-Alarm – Compact Battery Management for Lithium Smart Batteries

The Victron smallBMS with Pre-Alarm is a compact, cost-effective Battery Management System (BMS) designed specifically for Victron Lithium Battery Smart (LiFePO₄) batteries. It offers essential protection and monitoring features in a simplified design, making it ideal for systems that do not use VE.Bus inverters or inverter/chargers.

Key Features:

• Reliable Battery Protection
  Protects against over-voltage, under-voltage, and over-temperature events at the cell level.
• Built-In Pre-Alarm Functionality
  Provides a warning before a system shutdown, helping you take action before critical faults occur.
• Compact and Easy to Integrate
  Ideal for smaller or space-limited setups where full VE.Bus integration isn't required.

Important Note:

The smallBMS does not include a VE.Bus interface, and therefore cannot be used with VE.Bus inverter/chargers like the MultiPlus or Quattro. For those systems, consider the VE.Bus BMS V2.

This streamlined BMS is perfect for users who need efficient battery management without the complexity of a full VE.Bus system.
