This battery uses Lithium Iron Phosphate (LiFePO4) technology. Its main advantages include:

Robustness: It is less sensitive to prolonged deep discharges or partial charge states, unlike lead-acid batteries.Long service life: It offers a higher number of life cycles.High efficiency: Round-trip energy efficiency of 92%.Wide operating temperature range: It operates effectively in various climatic conditions.Low internal resistance: For better performance.No need for systematic full charging: Its lifespan is even slightly improved with partial charging.

This Victron Energy battery has a nominal voltage of 12.8 V and a nominal capacity of 330 Ah at 25 °C. This corresponds to a nominal energy of 4220 Wh at 25 °C.

The lifespan of this Victron Energy battery is excellent:

2500 cycles at 80 % depth of discharge (DoD)
3000 cycles at 70 % depth of discharge (DoD)
5000 cycles at 50 % depth of discharge (DoD)
These figures indicate the number of cycles before the battery’s capacity drops below 80 % of its nominal capacity.

The 12.8V/330Ah Smart Lithium battery delivers a round-trip energy efficiency of 92%. This efficiency is maintained even with shallow discharges, which is a significant advantage over lead-acid batteries.

The temperature ranges for this battery are as follows:

Discharge: from -20 °C to +50 °CDischarge: from +5 °C to +50 °CStorage: from -45 °C to +70 °CThe battery management system (BMS) will stop the charging process if the temperature becomes too high or too low to protect the battery.

The 12.8V/330Ah Smart Lithium battery has an IP22 protection rating. This means it is protected against solid objects larger than 12.5 mm and against dripping water (rain) up to 15° from the vertical.

LiFePO4 technology offers several key advantages compared to lead-acid batteries:

Extended lifespan: Significantly longer cycle life. Superior efficiency: Round-trip energy efficiency of 92% versus approximately 80% for lead-acid. No need for full charging: Lifespan is even improved by partial charges, unlike lead-acid which suffers from sulfation in deficit mode. Reduced weight and size: Up to 70% savings in weight and space. Wide operating temperature range. Better performance in shallow discharge.

Yes, this battery can be stored. The maximum recommended storage duration is 1 year at 25 °C. It is important to respect the storage temperature limits to preserve the battery.

Yes, these batteries are designed to be connected in series, parallel, or series/parallel. This allows building battery banks for 12 V, 24 V, or 48 V systems. A system can integrate up to 20 batteries, allowing a maximum storage capacity of 84 kWh in a 12 V configuration.

Yes, this Victron Energy Lithium Smart battery requires an external Battery Management System (BMS) to ensure its protection. While the battery includes cell balancing and monitoring, the external BMS is essential for managing critical safety functions.

The Battery Management System (BMS) plays a critical role in ensuring battery safety and longevity. Its main functions are:

Generate a pre-alarm if a cell voltage drops below 3.1 V (adjustable between 2.85 V and 3.15 V). Disconnect or stop charging if a cell voltage drops below 2.8 V (adjustable between 2.6 V and 2.8 V). Stop the charging process if a cell voltage exceeds 3.75 V, or if the temperature becomes too high or too low.

Thanks to their ability to be connected in series, parallel, or series/parallel, these batteries allow the construction of systems with different voltages:

12 V (in parallel or single battery)24 V (in series)48 V (in series)For 24 V and 48 V systems, it is recommended to use batteries with the corresponding nominal voltage (e.g., 24 V batteries for a 24 V system) to reduce the required balancing time.

It is important to note that this specific battery (12.8V/330Ah) cannot be placed on its side. It must be installed in a position that complies with the manufacturer's instructions to ensure safe and optimal operation. Handle it with care as it is sensitive to mechanical shocks.

For optimal charging and to preserve battery lifespan, the recommended charging voltages are:

Charging voltage: Between 14 V and 14.4 V (14.2 V is recommended). Float voltage: 13.5 V. These values are critical for proper operation and safety of the charging system.

Here are the current specifications for this battery:

Maximum continuous discharge current: 400 A
Recommended continuous discharge current: ≤ 300 A
Maximum charge current: 400 A
Recommended charge current: ≤ 150 A
It is important to respect these limits to ensure the battery's safety and long-term performance.

Power connection for this battery is made via M10 threaded inserts. It is essential to use cables with the appropriate cross-section and suitable fuses to ensure a safe and efficient connection.

Yes, it is strongly recommended to charge the battery before first use. LiFePO4 batteries can lose some of their charge during transport and storage. A full initial charge ensures all cells are balanced and the battery is ready to deliver its full capacity and operate optimally from the start.

Yes, these batteries are designed to be flexible and can be connected in series, parallel, or series/parallel. This allows you to build a battery bank suitable for 12 V, 24 V, or 48 V systems. A system can integrate up to 20 batteries.

It is important to note that each Victron Energy Lithium Smart battery requires an external Battery Management System (BMS). The BMS is essential to protect the battery from undervoltage, overvoltage, and extreme temperatures, ensuring its safety and longevity. Victron Energy offers six different BMS solutions, suitable for various applications.
