Victron Energy Lithium Battery offers high-performance energy storage with exceptional efficiency and long cycle life, designed for demanding applications. Engineered for reliability and safety, it provides stable power output and fast charging capabilities. Ideal for renewable energy systems, marine, and off-grid setups, this battery ensures consistent, lightweight, and maintenance-free operation. Its advanced lithium technology maximizes energy density while minimizing weight, delivering a durable and efficient power solution for expert-level energy management.
Victron Energy Lithium Battery Smart batteries are Lithium Iron Phosphate (LiFePO4) batteries and are available in 12.8 V or 25.6 V 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 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 of time (i.e. if the battery is rarely, or never at all, 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 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, a LFP battery will still achieve 90 % efficiency under shallow discharge conditions.
Size and weight
Saves up to 70 % in space
Saves up to 70 % in weight
Expensive?
LFP batteries are expensive when compared to lead-acid. But 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.
