The Victron LiFePO4 Battery 51.2V 100Ah NG is a lithium iron phosphate battery for off-grid, backup and solar storage installations. Nominal energy is 5.12kWh at 51.2V nominal voltage, suiting 48V battery bank set-ups used with Victron inverter-chargers and Multi systems. This is the NG (New Generation) variant, SKU BAT548110620.

Victron LiFePO4 battery key features

• Chemistry, Lithium Iron Phosphate (LiFePO4)
• Nominal voltage, 51.2V, matching 48V system architectures
• Capacity, 100Ah, giving 5.12kWh nominal energy per unit
• Series, NG (New Generation), Victron's current standalone LiFePO4 line
• Battery management, integrated BMS handles cell balancing and protection without an external unit
• Weight, 37kg

Product overview

The integrated BMS communicates with compatible Victron equipment, letting the system respond to battery state in real time. This matters in systems using a Victron MultiPlus, Quattro or other VE.Bus-compatible inverter-charger, where the BMS can signal charge current limits and disconnect commands directly to the inverter. Installers should check communication cable and protocol compatibility with the specific inverter or charge controller in use.

Units can be mounted upright and connected in parallel to increase capacity, or in series-parallel arrangements where the system design allows. Follow Victron's published wiring and fusing guidance for lithium battery banks. At 37kg, positioning during installation needs two people or mechanical assistance.

Applications

• Off-grid solar systems using 48V inverter-chargers such as the Victron MultiPlus or Quattro range
• Grid-tied battery backup systems requiring a 48V lithium bank for critical loads
• Marine and vehicle installations needing a 48V lithium battery with integrated BMS
• Commercial and agricultural off-grid sites with daily cycling
• Expanding existing Victron LiFePO4 NG battery banks by adding units in parallel

What's in the box
