Product Description

The Victron LiFePO4 Battery 12.8V 300Ah NG (BAT512130620) is a lithium iron phosphate battery built for off-grid, marine and mobile power systems needing a high-capacity 12V bank. It delivers 300Ah of capacity at 12.8V nominal, totalling 3.84kWh of energy storage.

Victron LiFePO4 battery features

  • Chemistry, lithium iron phosphate (LiFePO4), a stable cell technology with no thermal runaway risk associated with other lithium chemistries.
  • Voltage, 12.8V nominal, a direct replacement or upgrade for 12V lead-acid battery positions.
  • Capacity, 300Ah, giving 3.84kWh of total energy storage.
  • Series, NG (New Generation) with integrated battery management system (BMS) functionality.
  • Weight, 28kg.
  • Ecosystem, works with Victron charge controllers and inverter/chargers, including VE.Bus and Venus OS monitoring.

Why LiFePO4

LiFePO4 cells hold a flatter discharge curve than lead-acid, so usable voltage stays consistent until the battery is nearly depleted. That matters for inverters and loads sensitive to voltage drop. The integrated BMS in this NG series battery protects against overcharge, over-discharge, over-temperature and short circuit conditions, and communicates state-of-charge to compatible Victron equipment without extra external BMS hardware in many setups.

Batteries can be connected in series or parallel to build 24V or 48V banks, or to add capacity, following Victron's configuration guidelines.

Applications

  • Off-grid solar systems needing a high-capacity 12V or series-connected bank.
  • Marine and narrowboat house banks replacing lead-acid.
  • Motorhomes, expedition vehicles and other mobile power systems.
  • Backup power where long cycle life and low maintenance matter.
  • Victron systems built around MultiPlus, Quattro or SmartSolar equipment.

Installation notes

Fit by a qualified electrician or accredited installer familiar with lithium systems. Chargers and controllers must use lithium-specific charge profiles, not lead-acid settings. Follow Victron's published guidelines when wiring multiple batteries in series for BMS coordination.
