The Victron LiFePO4 25.6V 300Ah NG is a lithium iron phosphate battery from Victron's NG (New Generation) range, delivering 7.68kWh of energy from a single 25.6V unit. Built for off-grid systems, marine installs and large mobile power setups where depth of discharge and cycle life matter.

Key features

• Chemistry, Lithium Iron Phosphate (LiFePO4)
• Nominal voltage, 25.6V, suited to 24V system architecture
• Capacity, 300Ah, 7.68kWh of energy
• Protection, integrated BMS handling cell balancing, over-charge, over-discharge and short-circuit protection
• Bank building, units can be connected in series or parallel per Victron configuration guidelines
• Weight, 55kg

Product overview

LiFePO4 chemistry does not undergo thermal runaway under normal fault conditions, which is why it suits enclosed spaces such as boats, vehicles and battery rooms. Its flat discharge curve keeps voltage consistent through most of the discharge cycle, helping inverter efficiency and load performance.

At 300Ah, one unit covers medium-to-large off-grid loads without the need to manage multiple parallel batteries. The BMS handles cell-level protection on its own, though any connected charger or inverter/charger still needs its charge parameters set to the LiFePO4 profile Victron specifies. The NG designation marks this as part of Victron's updated lithium range, with improved BMS communication over earlier Victron lithium products, integrating with existing Victron monitoring and control setups.

Applications

• Off-grid solar systems in cabins, remote properties and agricultural buildings on a 24V bank
• Marine and narrowboat installations
• Large motorhome and vehicle-based 24V inverter/charger systems
• Backup power for telecoms, industrial equipment or critical loads on 24V DC infrastructure
• Expanding an existing Victron 24V battery bank with a single high-capacity unit

What's in the box

• 1x Victron LiFePO4 Battery 25.6V 300Ah NG (BAT524130620)

Installation notes

Installation should be carried out by a qualified electrician or accredited installer experienced with lithium battery systems. At 55kg, safe handling equipment is needed. Charge parameters on all connected chargers and inverter/chargers must be set to Victron's LiFePO4 profile before commissioning, and this battery should not be mixed with lead-acid or other lithium chemistries in the same bank.
