xVictron LiFePO4 Battery 12.8V 300Ah NG — BAT512130620
The Victron Energy LiFePO4 Battery 12.8V 300Ah NG is a lithium iron phosphate battery designed for professional off-grid, marine and mobile power applications. With 300Ah of usable capacity at 12.8V nominal voltage, it suits installers specifying high-capacity 12V battery banks where weight, cycle life and depth of discharge matter.
Key Features
- Lithium iron phosphate (LiFePO4) chemistry provides a stable, safe cell technology with no thermal runaway risk associated with other lithium chemistries.
- 12.8V nominal voltage makes it a direct replacement or upgrade for 12V lead-acid battery positions.
- 300Ah capacity delivers 3.84kWh of total energy storage, with high usable capacity compared to lead-acid equivalents.
- NG (New Generation) series design from Victron Energy with integrated battery management system (BMS) functionality.
- Weighs 28kg, significantly lighter than a comparable lead-acid battery bank of the same usable capacity.
- Compatible with Victron charge controllers, inverter/chargers and the wider Victron ecosystem including VE.Bus and Venus OS monitoring.
Product Overview
LiFePO4 chemistry is the preferred choice for professional battery installations where safety, longevity and consistent performance across a wide state-of-charge range are required. Unlike lead-acid batteries, LiFePO4 cells maintain a relatively flat discharge curve, meaning usable voltage stays consistent until the battery is nearly depleted. This matters in practice for inverters and loads that are sensitive to voltage drop.
The NG (New Generation) designation indicates this is part of Victron's updated lithium battery range. The integrated BMS protects the cells against overcharge, over-discharge, over-temperature and short circuit conditions. For installers working within the Victron ecosystem, this battery communicates with compatible Victron equipment, enabling state-of-charge monitoring and charge parameter coordination without additional external BMS hardware in many configurations.
At 300Ah and 28kg, this battery is well suited to applications where a single large-format 12V lithium unit is preferable to assembling a bank of smaller cells. It can be connected in series or parallel to build 24V or 48V systems, or to increase total capacity, subject to Victron's configuration guidelines.

Installation Notes
This battery should be installed by a qualified electrician or accredited installer familiar with lithium battery systems. LiFePO4 batteries require chargers and charge controllers programmed with lithium-specific charge profiles. Do not use charge equipment set to lead-acid profiles. When connecting multiple batteries in series to form 24V or 48V banks, follow Victron's published configuration guidelines to ensure BMS coordination. For solar PV installations in the UK, use an MCS-accredited installer where applicable.
