Victron Lithium Battery 24VDC 100Ah NG Smart LifePO4 [BAT524110620]

~~$2,106.00~~$1,790.10

Lithium Battery 24VDC 100Ah 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 (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 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

Victron Lithium Battery 12VDC - 180AH - Smart LifePO4 - Drop Ship Only f/$150 [BAT512118610]

~~$1,362.00~~$1,157.70

Lithium Battery 12VDC - 180AH - Smart LifePO4 - Drop Ship Only for $150

Victron Energy Lithium Battery Smart batteries are Lithium Iron Phosphate (LiFePO4). They are available in capacities of 12.8 V or 25.6 V. 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 20, which results in a maximum energy storage of 84 kWh in a 12 V system and up to 102 kWh in a 24 V¹) and 48 V¹) system.

A single LFP cell has a nominal voltage of 3.2 V. A 12.8 V battery consists of 4 cells connected in series and a 25.6 V battery consists of 8 cells connected in series.

Why lithium-iron-phosphate?

Rugged

A lead-acid battery will fail prematurely due to sulfation:

If it operates in deficit mode during long periods (i.e., if the battery is rarely, or never fully charged).
If it is left partially charged or worse, fully discharged (yacht or mobile home during wintertime).

A LFP battery:

Does not need to be fully charged. Service life even slightly improves in case of a partial charge instead of a full charge. This is a major advantage of LFP compared to lead acid.
Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance, and high efficiency (see below).

LFP is therefore the chemistry of choice for demanding applications.

Efficient

In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance.
The round-trip energy efficiency (discharge from 100 % to 0 % and back to 100 % charged) of the average lead-acid battery is 80 %.
The round-trip energy efficiency of a LFP battery is 92 %.
The charge process of lead-acid batteries becomes particularly inefficient when the 80 % state of charge has been reached, resulting in efficiencies of 50 % or even less in solar systems where several days of reserve energy is required (battery operating in 70 % to 100 % charged state).
In contrast, an LFP battery will still achieve 90 % efficiency under shallow discharge conditions.

Size & Weight

Saves up to 70 % in space
Saves up to 70 % in weight

Expensive?

LFP batteries are expensive when compared to lead-acid. However, in demanding applications, the high initial cost will be more than compensated by longer service life, superior reliability, and excellent efficiency.

Bluetooth

With Bluetooth cell voltages, temperature and alarm status can be monitored.
Instant readout: The VictronConnect App can display the most important data on the Device list page without the need to connect to the product.
Very useful to localize a (potential) problem, such as cell imbalance.

Six tailored BMS solutions

There are 6 different BMS models tailored for various applications available for use with the Lithium Battery Smart. The system design and BMS selection guide in the battery manual provide an overview and explain the differences between them and their typical use.

¹) To reduce the required balancing time, Victron recommends using as few different batteries in series as possible for the application. 24 V systems are best built using 24 V batteries. 48 V systems are best built using two 24 V batteries in series. While the alternative, four 12 V batteries in series, will work, it will require more periodic balancing time.

Victron LFP 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:

Generate a pre-alarm whenever the voltage of a battery cell decreases to less than 3.1 V (adjustable 2.85 V – 3.15 V).
Disconnect or shut down the load whenever the voltage of a battery cell decreases to less than 2.8 V (adjustable 2.6 V – 2.8 V).
Stop the charging process whenever the voltage of a battery cell increases to more than 3.75 V or when the temperature becomes too high or too low.
