Description
xVictron LiFePO4 Battery 12.8V 200Ah NG — BAT512120620
The Victron LiFePO4 Battery 12.8V 200Ah NG is a lithium iron phosphate battery from Victron's New Generation (NG) series, designed for 12V off-grid, marine, and mobile power systems. At 200Ah, it delivers 2.56kWh of usable capacity in a single unit, making it well suited to demanding energy storage applications where weight and cycle life matter.
Key Features
- Lithium iron phosphate (LiFePO4) chemistry provides a stable, thermally safe cell compared to other lithium types.
- 12.8V nominal voltage, 200Ah capacity, giving 2.56kWh per battery.
- New Generation (NG) series design with integrated battery management system (BMS) for cell balancing, over-charge, over-discharge, and short-circuit protection.
- Weighs 18.4kg, significantly lighter than an equivalent lead-acid battery of the same capacity.
- Compatible with Victron charge controllers, inverter/chargers, and the VE.Bus and VE.Direct ecosystem where supported by the NG BMS.
- Suitable for series and parallel connection to increase voltage or capacity, subject to Victron's configuration guidelines.
Product Overview
LiFePO4 chemistry is chosen for energy storage applications where safety and longevity are priorities. Unlike NMC or NCA lithium cells, LiFePO4 cells do not undergo thermal runaway under normal fault conditions, which makes them appropriate for enclosed spaces such as boat bilges, vehicle cabinets, and off-grid battery rooms. The flat discharge curve of LiFePO4 also means the battery maintains a near-constant voltage across most of its state of charge, which benefits inverters and DC loads that are sensitive to voltage drop.
The NG designation indicates this is Victron's updated generation of standalone lithium batteries. The integrated BMS handles cell-level protection without requiring a separate external BMS unit for basic operation, though integration with Victron system monitoring (via a compatible BMS interface or GX device) is recommended for full system visibility and protection coordination. At 200Ah and 12.8V nominal, this battery is a practical building block for 12V systems requiring substantial storage, and can be paralleled for higher capacity installations.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with lithium battery systems. LiFePO4 batteries require a lithium-compatible charger profile; do not use chargers set to AGM, gel, or standard lead-acid profiles. Ensure the charge source (solar charge controller, inverter/charger, or DC-DC charger) is configured correctly for 12.8V LiFePO4 chemistry before connecting. For marine and vehicle installations, secure the battery against movement and ensure adequate ventilation. Where this battery forms part of a grid-connected or larger off-grid system, coordinate BMS communication with the system controller to enable proper charge and load disconnect functions.
