12.8V/180Ah Smart Battery

This Victron Energy Smart battery uses Lithium Iron Phosphate (LiFePO4) technology. This chemistry is known for its robustness, efficiency, and long lifespan, particularly suited to demanding applications such as sailing or off-grid systems.

LiFePO4 batteries offer several significant advantages:

Superior energy efficiency: Round-trip efficiency of 92% compared to around 80% for lead-acid batteries.Long service life: They support a much higher number of charge/discharge cycles.Tolerance to partial discharges: Service life is even slightly improved with partial charges, unlike lead-acid batteries which require regular full charges.Wide operating temperature range: They operate effectively across a broader temperature range.Low internal resistance: Allows higher charge and discharge currents with fewer losses.Space and weight savings: Up to 70% savings in space and weight compared to equivalent lead-acid batteries.

This Victron Energy Smart battery has a nominal voltage of 12.8 V and a nominal capacity of 180 Ah at 25 °C. This represents a nominal energy of 2304 Wh at 25 °C.

The round-trip energy efficiency (100 % discharge to 0 % and back to 100 % charge) of this LiFePO4 battery is 92 %. It maintains an efficiency of around 90 % even with shallow discharges.

La durée de vie de cette batterie LiFePO4 dépend de la profondeur de décharge (DoD) :

2500 cycles à 80 % de DoD (décharge profonde).3000 cycles à 70 % de DoD.5000 cycles à 50 % de DoD.La capacité est considérée comme étant à 80 % ou plus de sa capacité nominale à la fin de ces cycles.

The internal resistance of this Victron Energy Lithium Smart 12.8 V/180 Ah battery is 0.9 mΩ.

The dimensions of this battery are 237 mm (height) x 321 mm (width) x 152 mm (depth). Its weight is 18 kg.

La batterie peut fonctionner dans les plages de température suivantes :

Pour la décharge : de -20 °C à +50 °C.Pour la charge : de +5 °C à +50 °C.Il est important de respecter ces plages pour garantir la sécurité et la longévité de la batterie.

The maximum continuous discharge current for this battery is 360 A. The recommended continuous discharge current is ≤ 180 A.

The maximum charging current for this battery is 360 A. The recommended charging current is ≤ 90 A.

For optimal performance, the recommended charge voltages are:

Charge voltage: between 14 V and 14.4 V (14.2 V is recommended). Float voltage: 13.5 V. These values apply to a 12 V system. For a 24 V system, the values would be double (28 V to 28.8 V for charging, 27 V for float).

Yes, this battery can be stored. The maximum recommended storage time at 25 °C is 1 year. It is advised to consult the manual for optimal storage conditions to preserve battery lifespan.

Yes, this 12.8 V battery can be configured in series, parallel, or series/parallel to build a battery bank suitable for 12 V, 24 V, or 48 V systems. A system can integrate up to 20 Smart batteries. For 24 V and 48 V systems, it is recommended to use batteries with a higher nominal voltage (e.g., 24 V batteries for a 24 V system) if available, to reduce the required balancing time.

Yes, connecting to a Battery Management System (BMS) is mandatory for the protection and proper operation of the battery. The BMS ensures disconnection in case of cell undervoltage, stops charging in case of overvoltage or inadequate temperature, thereby protecting the battery and the system.

Victron Energy offers several BMS models for various applications compatible with Lithium Smart batteries. Among the compatible BMS solutions are:

The Small BMSThe VE.Bus BMS V2The VE.Bus BMSThe Lynx Smart BMSThe Smart BMS CL 12/100The Smart BMS 12/200The choice of BMS will depend on your system configuration and requirements.

You can monitor battery status via Bluetooth using the VictronConnect app. This app allows you to view cell voltages, temperature, alarm status, and other critical data. It is also useful for quickly locating potential issues, such as cell imbalance.

Les batteries Victron Energy Lithium Smart peuvent être connectées en :

Parallèle : Pour augmenter la capacité totale du parc (la tension reste la même).Série : Pour augmenter la tension du système (la capacité reste la même).Série/Parallèle : Pour augmenter à la fois la tension et la capacité.Il est crucial de suivre les instructions du manuel pour le câblage et de s'assurer que toutes les batteries sont connectées à un BMS pour une protection adéquate.

When installing or handling, the following precautions are mandatory:

Wear protective goggles and appropriate clothing.Use insulated tools and avoid wearing metallic objects.Never place metallic objects or tools on the battery.Avoid short circuits, deep discharges, and excessive charge/discharge currents.Do not open or dismantle the battery.Handle the battery with care; it is sensitive to mechanical shocks and heavy (use lifting aids).Do not use a damaged battery.Protect the battery from water.

Yes, these Lithium Smart batteries can be connected in series, parallel, or series/parallel to create a battery bank suitable for 12 V, 24 V, or 48 V systems.

A single system can integrate up to 20 Smart batteries, allowing a maximum energy storage capacity of 84 kWh in a 12 V system and up to 102 kWh in a 24 V or 48 V system.

For 24 V systems, it is recommended to use 24 V batteries. For 48 V systems, it is preferable to use two 24 V batteries in series to reduce the required balancing time.

Battery monitoring is performed via Bluetooth using the VictronConnect app. This app allows you to view cell voltages, temperature, and alarm status in real time, which is very useful for quickly identifying potential issues such as cell imbalance.

Each battery includes a cell balancing and monitoring system. However, connecting to a Battery Management System (BMS) is mandatory to ensure complete protection. The BMS performs the following main functions:

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