Three 24V LFP Battery Models

The LFP 24V Battery Series is the longest running series of MG Energy Systems. The third generation LiFePO4 chemistry forms the basis of these safe and reliable batteries. The series includes three models:
    • LFP Standard: proven track record, reliable, easy to integrate. This battery is also particularly well-suited for refit projects.
    • The LFP SLP (High-Voltage) system achieves scalability up to 563 V DC through its use of Amphenol SurLok Plus connectors.
    • LFP IP (IP65): The housing, SLP  connectors, and M12 CAN-Bus connections are all sealed.

Together with the MG Master LV or Master HV a safe and efficient operation is ensured.

System Modularity

Scale from 24V up to 563V and up to 1 MWh The LFP 24V batteries connect easily in series and parallel, giving complete freedom to build systems that match any voltage or capacity requirement. For example, four 24V LFP batteries in series creates a system voltage of 96 Vdc.

Every battery includes an integrated slave BMS that communicates with the MG Master BMS through a galvanically-isolated CAN-Bus. The Master collects all cell and temperature data, balancing and protecting each module in real time.

For large or redundant systems, multiple Masters can be connected using SmartLink MX, ensuring reliable communication and safety even in critical installations.

Together they deliver a safe, monitored, and efficient energy storage system.

Certifications & Standards

Tested and approved for demanding applications All 24V LFP batteries comply with international safety and performance standards.
  • IEC-EN 62619 and IEC-EN 62620: certification for lithium battery safety and performance.
  • UN38.3: transport safety testing for lithium batteries.
  • ES-Trin: approval for use in inland waterway vessels.
  • Functional Safety | SIL-2: compliance with ISO 13849-1 | IEC 61508 for LFP IP together with the MG Master HV, verifying fault tolerance and system integrity in critical environments.
The LFP 24V Series has earned these approvals, certifying its compliance with the strict safety requirements of marine, mobile, and stationary applications.

Safety ++

Built for safe operation

Safety is integrated into every MG system from cell chemistry to control architecture. Each 24V LFP battery includes an intelligent slave BMS that monitors all cell voltages and temperatures, balancing keep the system within the safety boundaries.

Fields of Expertise

The modular design and wide voltage range make the LFP 24V Series suitable for many applications. Because each system can be configured from a few modules up to more than 1 MWh, the same battery platform can serve both compact and large-scale projects.

Questions And Answers

Q: What is the LFP 24 V Series used for?

A: The 24 V LiFePO4 batteries are used in scalable energy storage systems from small off-grid setups to large marine or industrial installations. MG Energy Systems designed them as the base building blocks for flexible DC systems up to 563 V.

Q: Can these batteries be connected in series and parallel?

A: Absolutely. Each battery module includes an integrated BMS that supports both series and parallel configurations. Up to 16 modules can be connected in series (or 22 with the SLP version) and multiple strings in parallel for higher capacity.

Q: What communication options are available?

A: The batteries communicate with the MG Master BMS via a galvanically-isolated CAN-Bus. Depending on the model, connections are available with RJ45 or M12 interfaces, ensuring reliable data exchange across the system.

Q: Are the batteries certified for marine and transport use?

A: Yes. The LFP 24 V batteries comply with IEC-EN 62619, IEC-EN 62620, and UN38.3. They also meet ES-Trin requirements for inland waterway vessels, making them suitable for regulated maritime applications.

Q: How is system safety managed?

A: Safety is achieved through LiFePO4 chemistry, internal BMS protection, and intelligent communication with the MG Master controller. For an in-depth explanation of all safety measures, visit the Safety & Reliability page.

Q: What is the expected service life?

A: Each module is rated for over 3500 to 4000 cycles at 80 % DOD. Actual life depends on temperature, load profile, and system management. MG Energy Systems designs all LFP modules for long-term operation in professional systems.

Q: Which Master controllers are compatible?

A: The LFP 24 V Series works with MG Master LV (24–96 V) and MG Master HV (48–900 V) controllers. The SmartLink MX can be added for redundant or larger multi-master systems.

Q: Can I expand the system later?

A: Certainly. The LFP batteries are fully modular and can be added in series or parallel as your energy needs grow. This makes them ideal for systems that require future scalability without replacing existing components.
