Victron miniBMS: The Cost-Effective Battery Management Solution

Discover the Victron miniBMS, a straightforward and budget-friendly alternative to the VE.Bus BMS, designed for seamless integration with Victron Smart LiFePo4 batteries. While it doesn't support VE.Bus MultiPlus and Quattro inverter/chargers due to the absence of a VE.Bus interface, the miniBMS excels in various applications with its three distinct outputs, mirroring the functionality of the VE.Bus BMS.

Load Disconnect Output for Enhanced Control

The Load Disconnect output, maintaining a normally high state, transitions to free floating under cell under-voltage conditions (default 2.8V/cell, adjustable between 2.6V and 2.8V per cell), with a maximum current capacity of 1A. This output, not safeguarded against short circuits, is ideal for managing:

  • High current relays or contactors.
  • The remote on/off inputs of Battery Protects, inverters, DC-DC converters, or other loads, ensuring compatibility with various devices (refer to our detailed manual for specific cable requirements).

Pre-Alarm Output for Early Warning

Featuring a normally free-floating pre-alarm output that activates under imminent cell under-voltage scenarios (default 3.1V/cell, adjustable between 2.85V and 3.15V per cell), this function provides a crucial early warning with a 1A maximum current (not short circuit protected) and a minimum 30-second delay before load disconnect.

Charge Disconnect Output for Safe Charging

The Charge Disconnect output, typically high, becomes free floating to signal imminent cell over-voltage or over-temperature conditions, with a 10mA maximum current. This output, unsuitable for powering inductive loads like relay coils, facilitates:

  • Remote on/off control of chargers.
  • Integration with Cyrix-Li-Charge relays and Cyrix-Li-ct Battery Combiners, ensuring a versatile and safe charging environment.

System On/Off Input for Simplified Operation

Control the system effortlessly with the on/off input, affecting both outputs to ensure loads and chargers are deactivated when necessary. This feature accommodates a variety of control methods, including direct connections between terminals Remote L and H or adjustments to battery plus/minus.

Comprehensive Protection Across Voltage Systems

Designed to safeguard 12V, 24V, and 48V systems with an operating voltage range of 8 to 70V DC, the miniBMS offers versatile protection for a wide array of power setups.

Intuitive LED Indicators for Immediate Status Updates

  • Load ON (Blue): Indicates active load output (cell voltage >2.8V, adjustable on the battery).
  • Temp or OVP (Red): Signifies the charger output is free floating due to cell over-temperature (>50°C), under-temperature (<5°C), or over-voltage conditions.

Optimize your energy system with the Victron miniBMS, the economical choice for advanced battery management. Visit our website for detailed manuals and further information on integrating the miniBMS into your Victron energy setup.

Off-Grid and Backup

The presence of a functional electricity grid is not always as obvious as it would seem to be. An insufficient infrastructure is often the cause for an unreliable grid. Things become even more difficult when there is no grid at all. And yet you are in need of a reliable electricity supply. A local and properly functioning system is the only answer at this point. Victron Energy offers you such an answer. We are proud to offer you our modern translation for freedom and independence. Energy, Anytime, Anywhere

Marine

Whether you’re going on a short fishing trip or planning to sail across the ocean, you’ll need reliable power to enjoy your adventure to the fullest. But at Victron we believe reliability isn’t enough. We believe in Optimal Energy instead. In our view, a boat needs an intelligent power grid that adapts to any challenges you may encounter. With unparalleled reliability, without effort and at great value for money. That’s what we call Optimal Energy.

Energy Storage

As more solar and wind power comes on line, it becomes increasingly difficult and expensive, to ensure stability of the grid. Intermediate energy storage is therefore rapidly becoming an essential tool to keep power fluctuations on the grid within manageable limits. Moreover, as feed-in tariffs are decreasing, the business case for a home energy storage system that increases self-consumption becomes more solid every day. Intermediate energy storage increases self-consumption of harvested solar and/or wind power. The natural next step is 100% self-consumption and independence from the grid.
