smallBMS

is an advanced battery management system, dedicated to working with batteries Victron Energy LiFePO4 Smart It allows you to manage individual batteries as well as connect them into power banks, in both parallel and series configurations. Thanks to built-in protection and monitoring functions, smallBMS effectively extends the life of batteries, while ensuring their safety when working in various applications, from home installations to more complex industrial systems.
System smallBMS offers comprehensive battery management, monitoring charge status and cell health. Thanks to the built-in microprocessor, users can effectively control and optimize the performance of their batteries, which contributes to increased efficiency and extended system life. The device automatically manages both the charging and discharging processes, ensuring that the batteries are not excessively discharged or overcharged, which is crucial for ensuring their long-term durability.

Advanced Protection and Security Features

is equipped with a number of protective features that minimize the risk of cell damage, such as protection against overcharging, over-discharging and overheating These features are crucial for ensuring battery longevity and safety, especially in more demanding applications where power system reliability is paramount. Overheating protection is particularly important, ensuring the batteries are not damaged even in harsh environmental conditions where temperatures may exceed optimal levels. The device monitors cell health, shutting down power if temperatures become too high, thus preventing thermal damage.
smallBMS It is also equipped with three outputs that offer versatility in system management. Load shedding output is responsible for controlling high-current relays or contactors, ensuring that the power is disconnected when the cell voltage drops below a certain level. Pre-alarm output signals an approaching undervoltage, which allows for early reaction before shutting down the system. Charge disconnect output protects batteries against overvoltage, which is extremely important during the charging process, especially in situations where the cells may overheat.

Universal Integration and High Compatibility

was designed with the idea of easy integration with various lithium iron phosphate (LiFePO4) battery systems. With simple installation and flexible configuration options, this system is ideal for a variety of applications, both small and large. It allows users to integrate with Victron Smart LiFePO4 batteries, equipped with M8 round connectors, which makes smallBMS is versatile and easily adapts to various technical requirements.
smallBMS also offers the ability to control devices such as Battery Protect, Cyrix-Li-Charge relays or Cyrix-Li-ct battery connectors, which further enhances its functionality. The system can also be easily turned on and off using an external remote on/off switch, making it easier to manage the entire power system. Built-in LED indicators inform the user about the current status of the system, providing immediate access to information about the load status, temperature and possible voltage problems.
