12,8 V/100Ah Smart baterija

This Victron Energy battery uses Lithium Iron Phosphate (LiFePO4) technology. This chemistry is recognized for its robustness, long lifespan, safety, and high energy efficiency, making it ideal for marine and mobile applications.

This battery has a nominal voltage of 12.8 V and a nominal capacity of 100 Ah at 25 °C, providing a nominal energy of 1280 Wh. It is designed for 12 V, 24 V, or 48 V systems and includes Bluetooth connectivity for smart monitoring.

Yes, this 12.8 V battery can be wired in series to create battery banks for 24 V or 48 V systems. For example, two batteries in series for 24 V, or four for 48 V. Battery banks can be built up to a maximum of 20 units in a single system.

LiFePO4 batteries offer several significant advantages:

They do not need to be fully charged to extend their lifespan.They have a round-trip energy efficiency of 92 %, compared to about 80 % for lead-acid.They have a much longer lifespan, with 2500 cycles at 80 % depth of discharge (DoD) and up to 5000 cycles at 50 % DoD.They allow a reduction in space and weight by up to 70 % for an equivalent capacity.

The battery's lifespan depends on the depth of discharge (DoD):

2,500 cycles at 80% DoD. 3,000 cycles at 70% DoD. 5,000 cycles at 50% DoD.

Yes, a Battery Management System (BMS) is essential for the proper operation and protection of this LiFePO4 battery. The BMS protects against undervoltage, overvoltage, and extreme temperatures, and manages cell balancing.

The 'Smart' function indicates that the battery is equipped with Bluetooth connectivity. This allows you to monitor cell voltages, temperature, and alarm status in real time via the VictronConnect app on your smartphone or tablet. This feature is particularly useful for quick diagnostics, especially in cases of cell imbalance.

The battery cell balancing and monitoring cables can be connected in series (daisy-chain) and must be wired to a Battery Management System (BMS). The BMS connection is made via a male-to-female cable with an M8 circular connector, 50 cm long.

The BMS provides essential protections:

It generates a pre-alarm if a cell voltage drops below 3.1 V (adjustable between 2.85 V and 3.15 V). It disconnects charging if a cell voltage drops below 2.8 V (adjustable between 2.6 V and 2.8 V). It stops the charging process if a cell voltage exceeds 3.75 V or if the temperature is too high or too low.

Recommended operating temperatures are:

Discharge: from -20 °C to +50 °C. Charge: from +5 °C to +50 °C. Storage: from -45 °C to +70 °C.

The end-of-discharge voltage for this 12.8 V battery is 11.2 V. The BMS will disconnect the load if any individual cell voltage drops below 2.8 V to protect the battery.

The dimensions of this battery are 197 mm (height) x 321 mm (width) x 152 mm (depth). Its weight is 14 kg.

Yes, this 12.8 V / 100 Ah battery model can be mounted on its side, providing greater flexibility for installation in various spaces. Ensure it is properly and securely fastened.

To charge this LiFePO4 battery, you must use a charger compatible with lithium batteries, capable of providing the recommended charge and float voltages (14.2 V and 13.5 V respectively for a 12 V system) and managing the appropriate charging current (recommended ≤50 A).

The battery is equipped with M8 threaded insert connection terminals to ensure a robust and secure electrical connection.

This LiFePO4 battery has an excellent round-trip energy efficiency of 92%. This means very little energy is lost during charge and discharge cycles, which is particularly beneficial for off-grid solar or wind systems.

Yes, an initial charge of the battery is recommended before first use to ensure it is ready to operate optimally and to balance the cells if necessary.

Using the built-in Bluetooth function and the VictronConnect app, you can individually monitor cell voltages, temperature, and alarm status. This allows you to quickly detect any potential imbalance or issues at the cell level.
