Victron Energy Lithium Battery Smart batteries utilize Lithium Iron Phosphate (LiFePO4) technology, offered in 12.8 V or 25.6 V configurations with various capacities. These batteries are versatile, allowing series, parallel, or series/parallel connections, enabling the creation of battery banks for 12 V, 24 V, or 48 V system voltages. The system can accommodate up to 20 batteries, providing a maximum energy storage of 84 kWh in a 12 V system and up to 102 kWh in 24 V and 48 V systems.
Each LFP cell has a nominal voltage of 3.2V, with a 12.8 V battery comprising 4 cells and a 25.6 V battery consisting of 8 cells in series. Noteworthy advantages of LFP include tolerance to partial charging, a wide operating temperature range, excellent cycling performance, low internal resistance, and high efficiency.
In terms of efficiency, LFP outperforms lead-acid batteries, achieving a 92% round-trip energy efficiency compared to the 80% of lead-acid. LFP excels in applications demanding energy efficiency, offering significant space and weight savings of up to 70%. While LFP batteries may entail higher initial costs, their extended service life, superior reliability, and exceptional efficiency justify the investment, especially in demanding applications.
Equipped with Bluetooth functionality, these batteries enable real-time monitoring of cell voltages, temperature, and alarm status. The VictronConnect App provides instant data display without physical connection, aiding in problem localization, such as cell imbalance, for efficient maintenance.
