Victron Lithium NG Batteries:
Victron Energy Lithium NG batteries are Lithium Iron Phosphate (LiFePO4 or LFP) batteries available with
a nominal voltage of 12.8 V, 25.6 V and 51.2 V 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 12 V, 24 V or 48 V. The maximum number of batteries in one system is 50, which results in a maximum energy storage of 192 kWh in a 12 V system and up to 384 kWh in a 24 V and 48 V system.
Building upon the success of our Lithium Smart Series, the NG (Next Generation) series incorporates significant enhancements. Tailored for those seeking advanced and reliable energy storage, the Lithium NG series marks a pivotal advancement in our product lineup, ready to meet the demands of tomorrow.
Note: Victron NG Lithium Batteries must be used with Lynx Smart BMS NG 500A or 1000A
Highlights:
- 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.
Features:
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 centre, 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 connection. The BMS (from now on Lynx Smart BMS NG 500 A/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 centre 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.
Battery Management System (BMS):
Our Lithium NG batteries have integrated cell balancing and cell monitoring. The cell balancing/monitoring cables can be daisy-chained and must be connected to a Battery Management System (BMS).
The BMS will:
1. Generate a pre-alarm whenever the voltage of a battery cell decreases to less than 3.0 V.
2. Disconnect or shut down the load whenever the voltage of a battery cell decreases to less than 2.8 V.
3. Stop the charging process whenever the voltage of a battery cell increases to more than 3.6 V or when the temperature becomes too high or too low.
