Victron LiFePO4 Battery 12,8V/300Ah NG - BAT512130620

Victron Energy Lithium NG 12.8V 300Ah batteries are a next-generation lithium iron phosphate (LiFePO4 or LFP) battery designed for high-performance energy storage. The NG range is available in 12V, 24V, and 48V configurations, offering scalable energy storage solutions for off-grid solar systems, marine applications, RVs and commercial installations.

The Lithium NG series builds on the success of the Victron Lithium Smart range, incorporating key improvements in performance, monitoring, and installation flexibility. Batteries can be connected in parallel, series, or a combination of both, supporting system voltages of 12V, 24V, or 48V. A single system can include up to 50 batteries with 12.8V or 25.6V batteries (25 with 51.2V batteries), for a maximum of 192 kWh with 12V batteries, 384 kWh with 24V batteries and 128 kWh with 48V batteries.

Note: these batteries need a Victron BMS NG, sold separately: the Lynx Smart BMS NG 500A or 1000A, the VE.Bus BMS NG or the smallBMS NG. The BMS manages automatic setup, monitoring and system control.

Main features:

• Built-in cell voltage and temperature monitoring

• Up to 50 of these batteries in one system, for up to 192 kWh

• Available in 12V, 24V, and 48V models

• IP65-rated for dust and water resistance

• Secure mounting with bracket and strap options

The Lithium NG batteries have built-in cell monitoring and balancing, connected by cable to an external Victron BMS NG. The BMS continuously monitors battery voltage, current, and temperature, using this data to calculate the state of charge and trigger warnings or shutdowns as required. This information can be accessed via the VictronConnect app, a GX device, or the Victron VRM Portal.

The BMS performs key protective functions, including:

• Pre-alarm activation when a cell voltage drops below 3.0V

• Load disconnection when a cell voltage drops below 2.8V

• Charge shutdown when a cell voltage exceeds 3.6V or when temperatures are outside safe limits

The Lithium NG batteries are designed for easy installation, with secure bracket mounting options and a robust IP65-rated enclosure. Their low self-discharge rate, no more than 3 percent per month at 25°C, ensures reliable long-term performance.
