Product information

MG HP 25.2V 180Ah 4500Wh High Voltage Battery

HP Series (Lithium batteries)

The MG HP 25.2V 180Ah 4500Wh high voltage battery, like all the HP series, is based on high energy density cells. This means that they offer more energy for less weight. The integrated battery management system offers the highest safety standards and provides information on battery status and other parameters such as battery voltage or temperature.

Great flexibility in configuring battery banks can be achieved with the HP series due to its modular design. HP series batteries, such as the MG HP 25.2V 180Ah 4500Wh high voltage battery, are typically used for starter motors or in high temperature environments.

HP Series Features

  • High power output
  • Integrated battery management system (BMS)
  • Scalable system design due to 25.2 V modules
  • High safety standards
  • Plug and Play: Automatic configuration
  • For motor starting applications


The HP series batteries can be used in a variety of applications in different sectors such as marine, industrial or self-consumption photovoltaic.

The HP series has been specifically designed for use in applications where more power is required, such as starter motors, and in places where the ambient temperature is higher than usual, such as industrial installations with machinery contained in small rooms.


The connections to communicate the batteries and the MG Master HV unit can be established with the more economical RJ45 cables or with the more robust and secure M12 cables. Both options can be used in low voltage battery banks up to 96V. In high voltage ranges above 96V, only M12 cables can be used.


Each battery has an integrated BMS, battery management system. The BMS is an intelligent electronic module that measures the voltage and temperature of all cells to control that the balance between each cell and the battery module is correct.

The battery modules communicate with the MG Master HV (which acts as the master BMS) via an isolated galvanized CAN-Bus. The MG Master HV manages and monitors the status of all connected batteries. If the values of any of the modules exceed the limits set in its configuration, the MG Master will take control and protect the connected batteries from possible failures.

Control and monitoring

Monitoring, protection and control are very important factors in creating safe, simple and reliable battery systems. The MG Master HV is the control and safety unit of the MG battery system. It protects the connected batteries from extreme variations in charge and temperature and controls the balance between the battery cells. In addition to this safety function, the MG Master HV monitors and controls other important parameters to give the user information about battery health or energy consumption.

The MG CAN-Bus protocol can be used to communicate with other applications and multifunctional monitors via NMEA2000 and web interface. The MG Master HV guarantees a safe and suitable installation for any battery system thanks to its integrated safety electronics.

Storage systems

Flexibility in designing storage systems is one of the key features of the products of MG Energy Systems.

The combination of HP batteries in series with a Master BMS creates a perfect system for a wide range of applications. Redundant systems can also be created by connecting multiple Master BMS in parallel to increase system capacity and safety.
