Victron Energy Lithium NG Series 12V 300Ah Smart LiFePO4 Battery (Part Number BAT512130620)

Lithium Battery 12VDC 300Ah NG Smart LiFePO4

The NG (Next Generation) series builds on the achievements of the Lithium Smart Series, featuring substantial improvements. Designed for individuals in need of sophisticated and dependable energy storage solutions, the Lithium NG series represents a crucial development in our product range, prepared to address the challenges of the future.

Victron Energy Lithium NG batteries are Lithium Iron Phosphate (LiFePO4 or LFP) batteries available with nominal voltages of 12.8V, 25.6V, and 51.2V in various capacities. They can be connected in series, parallel, and series/parallel so that a battery bank can be built for system voltages of 12V, 24V, or 48V. The maximum number of batteries in one system is 50, which results in a maximum energy storage of 192 kWh in a 12V system and up to 384 kWh in a 24V and 48V system.

Integrated shunt

The battery data (battery voltage, current, and temperature) are transmitted to the BMS and evaluated there, i.e. to calculate the state of charge, which can then be read out via VictronConnect or a GX communication center, or to create and issue specific warnings and alarms.

Automatic setup, monitoring, and control via VictronConnect App or a GX device and the VRM Portal

All battery parameters are managed by the BMS automatically. The BMS automatically detects the system voltage and the number of batteries in parallel, series, and series/parallel connections. The BMS (Lynx Smart BMS NG 500A and 1000 A, further models to follow) is mandatory and must be purchased separately.

Monitoring and control take place via VictronConnect (every BMS model has Bluetooth), a GX communication center, or the VRM Portal. You can view battery parameters such as cell status, cell voltages, battery current, and temperatures in real time. The battery firmware is automatically updated by the BMS.

Easy bracket mounting

Mounting brackets make the installation easier and ensure that the battery is optimally secured against slipping and tipping over.

Increased ingress protection (IP-rating)

The Lithium NG batteries are effectively sealed against dust and can withstand low-pressure water jets, making them suitable for environments where exposure to dust and water is a concern.

Low self-discharge rate

The self-discharge rate has been significantly improved and is now a maximum of 2 % of the battery capacity per month. A low self-discharge rate contributes to the overall performance, longevity, and reliability of the NG batteries.

Features:

• Multiple improvements including added read-out of cell voltages and temperatures


• Maximum single bank size increased to 385kWh


• Modules available in 12, 24 and 48V


• Protection class IP65


• Bracket mounting and strap mounting
