Victron Energy SmallBMS NG Controller: Intelligent Protection for Your Lithium Battery System
Ensure the safety, reliability, and longevity of your valuable Victron Smart Lithium (LiFePO4) batteries with the Victron Energy SmallBMS NG. This compact yet powerful Battery Management System (BMS) acts as the essential safeguard for your 12V power system, making it a non-negotiable component for any serious installation in marine, RV, automotive, or off-grid applications. The SmallBMS NG is engineered to protect each individual cell of your lithium battery bank from the dangers of over-voltage, under-voltage, and high temperatures, preventing irreversible damage and maximizing your investment.
By intelligently managing your power system, the SmallBMS NG provides complete peace of mind. It is designed to seamlessly integrate into the Victron Energy ecosystem, offering sophisticated control over both charging and discharging processes to maintain optimal battery health.
Key Benefits:
* Ultimate Battery Protection: The primary function of the SmallBMS NG is to protect your expensive LiFePO4 batteries. It will automatically disconnect loads and/or chargers in the event of critical cell under-voltage, over-voltage, or over-temperature conditions, thereby preventing catastrophic failure and extending the battery´s service life significantly.
* Proactive Pre-Alarm System: A standout feature is the dedicated pre-alarm output. Before initiating a full system shutdown due to low cell voltage, the SmallBMS NG activates a pre-alarm. This gives you a crucial warning, allowing you to take corrective action—such as reducing load or starting a generator—before power is completely cut off.
* Intelligent System Control: The BMS provides dedicated outputs to manage both your system´s loads and chargers. It can control the remote on/off ports of Victron BatteryProtect units, inverters, DC-DC converters, and chargers, ensuring that charging and discharging cease precisely when required.
* Simplified System Operation: Featuring a connector for a remote on/off switch, the SmallBMS NG allows you to conveniently turn your entire DC system on or off from a single, accessible location. This simplifies daily operation and provides a quick-access master switch for maintenance or emergencies.
* Seamless Ecosystem Integration: Designed by Victron Energy for Victron Energy products, this BMS controller guarantees flawless communication and operation with Victron Smart Lithium batteries, Phoenix Inverters, BlueSolar and SmartSolar MPPT charge controllers, and other compatible devices.
Main Features:
* Load Disconnect output to control a relay, contactor, or the remote on/off port of system loads.
* Charge Disconnect output to manage the remote on/off port of battery chargers and solar controllers.
* Dedicated, potential-free pre-alarm contact that activates before a low-voltage disconnect.
* Integrated remote on/off terminal for a system-wide master switch.
* Clear LED indicators for providing instant operational status.
* Designed specifically for use with Victron Energy Smart Lithium 12.8V batteries.
