Description
xVictron LiFePO4 Battery 25.6V 300Ah NG — BAT524130620
The Victron Energy LiFePO4 25.6V 300Ah NG is a high-capacity lithium iron phosphate battery from the Victron NG (New Generation) series. At 7.68kWh of usable capacity in a single unit, it is suited to off-grid systems, large mobile installations, and backup power applications where cycle life and depth of discharge matter.
Key Features
- Lithium iron phosphate (LiFePO4) chemistry provides stable, safe operation across a wide range of temperatures and charge states.
- 25.6V nominal voltage (8-cell configuration) delivers 7.68kWh of energy per unit.
- 300Ah capacity supports high continuous loads and extended autonomy without requiring multiple parallel strings.
- NG (New Generation) series design with integrated battery management system (BMS) for cell balancing, over-charge, over-discharge and short-circuit protection.
- Units can be connected in series or parallel to build larger battery banks, subject to Victron configuration guidelines.
- Weighs 55kg, reflecting the high energy density achievable with LiFePO4 at this capacity.
- Compatible with the Victron ecosystem including Victron charge controllers, inverter/chargers and the VE.Bus and VE.Can communication networks where applicable.
Product Overview
LiFePO4 chemistry is the preferred choice for stationary and mobile energy storage where safety and longevity are priorities. Unlike NMC or NCA lithium cells, LiFePO4 does not undergo thermal runaway under normal fault conditions, making it appropriate for enclosed installations such as boats, vehicles and battery rooms. The flat discharge curve also means the battery delivers consistent voltage throughout most of its discharge cycle, which benefits inverter efficiency and load performance.
The 25.6V nominal voltage makes this battery a direct fit for 24V system architectures, which are common in off-grid cabins, marine vessels and larger mobile applications. At 300Ah, a single unit provides enough capacity for most medium-to-large off-grid loads without the complexity of managing multiple parallel batteries. The integrated BMS handles cell-level protection autonomously, but it is still essential to configure the charge parameters of any connected charger or inverter/charger to match the LiFePO4 charge profile specified by Victron.
The NG designation indicates this is part of Victron's updated lithium battery range, which brings improvements to the BMS communication and integration capabilities compared to earlier Victron lithium products. Installers already working within the Victron ecosystem will find this battery integrates directly with existing monitoring and control infrastructure.

Installation Notes
This battery must be installed by a qualified electrician or accredited installer with experience in lithium battery systems. At 55kg, safe handling equipment is required during installation. Charge parameters on all connected chargers and inverter/chargers must be set to the LiFePO4 profile recommended by Victron before commissioning. Do not mix this battery with lead-acid batteries or other lithium chemistries in the same bank. For off-grid solar installations, ensure the system design accounts for the BMS disconnect behaviour under fault conditions to avoid unexpected load interruptions.
