Victron Lithium-NG Battery 100Ah 51.2V BMS Integrated Shunt Next Generation

The Victron Energy 51.2V/100Ah Lithium NG battery (MPN BAT548110620) is a high-quality, latest-generation LiFePO4 battery that stands out for its high performance and long service life. It allows flexible integration into energy systems and can be connected in series, parallel, or in combination to support different configurations. An integrated shunt allows precise monitoring of voltage, current, and temperature via the VictronConnect app or a GX device. With a low self-discharge rate of no more than 2% per month, this battery offers a reliable and long-lasting solution for modern energy requirements.

Highlights of the Lithium NG battery

• Integrated shunt for precise monitoring
• Intelligent battery management system
• Setup and control in the VRM portal
• High energy density
• Long service life
• Superior temperature stability
• Low self-discharge rate
• Easy bracket mounting

Setup and control with VictronConnect, GX device, or VRM portal

All battery parameters are managed fully automatically by the BMS. The system automatically detects the system voltage and the number of batteries, regardless of whether they are operated in parallel, series, or series/parallel connection. The Lynx Smart BMS (currently available in NG 500 A / 1000 A versions) is mandatory and must be purchased separately.

Monitoring and control is done via the VictronConnect app (Bluetooth is integrated in all BMS models), a GX communication center, or the VRM portal. In addition, the system enables real-time display of battery parameters such as cell status, voltages, currents, and temperatures. Firmware updates for the battery are performed automatically via the BMS.

Tasks of the BMS:

1. Trigger a pre-alarm when the voltage of a battery cell falls below 3.0 V.
2. Disconnect or switch off the load as soon as the voltage of a battery cell falls below 2.8 V.
3. Interrupt the charging process if the voltage of a battery cell exceeds 3.6 V or the temperature is outside the permissible range (too high or too low).

Advantages of the NG series

The NG series from Victron Energy offers numerous advantages over conventional lithium batteries, making it particularly attractive. One of its most outstanding features is its improved service life, which is achieved through advanced cell technology, enabling the battery to deliver a higher cycle count even under intensive use. In addition, the Lithium NG battery is characterized by its superior temperature stability, which means that it can operate efficiently under extreme conditions. With higher discharge performance and faster charging times, NG batteries also offer a more reliable power supply that meets the requirements of modern energy systems.
