Description
xVictron LiFePO4 Battery 25.6V 200Ah NG — BAT524120620
The Victron LiFePO4 25.6V 200Ah NG is a lithium iron phosphate battery from Victron's New Generation (NG) series, designed for demanding off-grid, marine and backup power applications. At 5.12kWh nominal capacity, it suits installations where weight, cycle life and depth of discharge matter. This battery is intended for professional installation as part of a larger Victron system.
Key Features
- 25.6V nominal voltage with 200Ah capacity, delivering 5.12kWh per unit.
- Lithium iron phosphate (LiFePO4) chemistry offers a stable, thermally safe cell type compared to other lithium formats.
- New Generation (NG) series design from Victron Energy, built for integration with Victron inverter-chargers and MPPT charge controllers.
- High depth of discharge capability, allowing more usable energy per cycle than lead-acid equivalents.
- Significantly lighter than equivalent lead-acid battery banks, at 37kg for 200Ah at 25.6V.
- SKU BAT524120620 with GTIN 8719076058946 for straightforward procurement and stock management.
Product Overview
LiFePO4 chemistry is well established in professional solar and off-grid installations. It offers a flat discharge curve, meaning voltage remains relatively stable across most of the discharge cycle. This matters in practice because inverters and loads receive a more consistent supply voltage, reducing the risk of premature low-voltage shutdowns. The chemistry is also more thermally stable than lithium cobalt or NMC alternatives, which is relevant in enclosed or marine environments.
The 25.6V nominal voltage makes this battery suitable for 24V system architectures. Two units can be connected in series to form a 51.2V (nominally 48V) bank, or multiple units can be connected in parallel to increase capacity at 24V. The NG designation indicates this is Victron's updated platform, designed for compatibility with current Victron BMS and communication products. Always verify BMS compatibility with the specific Victron components in your system before specifying.
At 37kg, this is a substantial unit. Installation planning should account for mounting surface load ratings, cable sizing for the current involved, and safe handling procedures during commissioning.

Installation Notes
This battery must be installed by a qualified electrician or accredited installer with experience in lithium battery systems. LiFePO4 batteries require a compatible battery management system (BMS) and a charger or inverter-charger programmed for lithium charge profiles. Do not use lead-acid charge settings. Ensure all cabling is correctly rated for the maximum discharge current, and that fusing is installed as close to the battery terminal as practicable. For systems connected to the grid, ensure the installation meets current UK wiring regulations and any applicable G98 or G99 requirements for the wider system.
