Detailed description

Designed for demanding marine energy systems, the Victron Energy Smart 25.6V 100Ah lithium battery offers an energy storage solution based on Lithium Iron Phosphate (LiFePO4) technology. This chemistry is recognized for its robustness and tolerance to undercharge operating modes, extending useful life even with partial recharges. It supports a wide operating temperature range, ensuring stable performance in various environments. With a round-trip efficiency of 92%, it outperforms the average 80% efficiency of lead-acid batteries and maintains 90% efficiency even in shallow discharge conditions.

System integration and performance

The Smart 25.6V 100Ah battery can be connected in series, parallel, or series/parallel, allowing the construction of battery banks for 12 V, 24 V, or 48 V systems. A single system can integrate up to 20 batteries, with a maximum energy storage capacity of 102 kWh for 24 V and 48 V systems. It includes cell balancing and monitoring. An external Battery Management System (BMS) is required for protection, managing load disconnection if cell voltage drops below 2.8 V, and charging shutdown if a cell voltage exceeds 3.75 V or in case of extreme temperature. Six BMS models are available from Victron Energy to suit various configurations.

Positioning and physical characteristics

Positioned in Victron Energy’s Smart range, this 25.6V 100Ah battery offers a balance between capacity and footprint for 24 V installations. It differs from 12.8 V models by its nominal voltage, simplifying 24 V system architectures compared to assembling two 12.8 V batteries in series. It provides lower capacity than the 25.6V 200Ah version, making it suitable for intermediate energy needs. Integrated Bluetooth connectivity allows monitoring of cell voltages, temperature, and alarm status via the VictronConnect app. It weighs 32.5 kg, enabling space and weight savings of up to 70% compared to lead-acid batteries. The battery features IP22 protection.

Expert opinion

« Technical evaluation: Victron Energy Smart LiFePO4 25.6V 100Ah battery »

This battery is particularly suited to mid-sized sailboats and powerboats, as well as standalone solar installations where reliability and energy efficiency are critical. Its LiFePO4 technology is a major asset for applications where the battery is frequently used in partial charge mode—a common situation in sailing or at remote sites—unlike lead-acid batteries, which suffer from premature sulfation under these conditions.

Integration into the system requires the appropriate selection of a Victron Energy BMS, essential for protection against overvoltage, undervoltage, and extreme cell temperatures. The choice of BMS (Small BMS, VE.Bus BMS, Lynx Smart BMS, etc.) depends on installation complexity and integration with other Victron equipment (chargers, inverters). Bluetooth connectivity via the VictronConnect app is a major advantage for real-time diagnostics and monitoring of critical battery parameters, enabling early detection of potential cell imbalances.

Compared to the 25.6V 200Ah version, this 100Ah model offers a favorable compromise for confined spaces or intermediate energy needs, without sacrificing the benefits of LiFePO4 technology. It is crucial to note that its IP22 rating requires installation in a dry compartment protected from direct water spray, despite its inherent robustness. Special attention must be given to cable sizing and fuse selection to handle high discharge and charge currents.

Frequently Asked Questions

Need help? Contact us

What is the nominal voltage of this Smart lithium battery?

The nominal voltage of this Smart lithium battery is 25.6 V. It consists of eight LiFePO4 cells connected in series, each cell having a nominal voltage of 3.2 V.

What is the capacity of this Victron Energy battery?

This Victron Energy battery has a rated capacity of 100 Ah at 25 °C. It delivers a nominal energy of 2560 Wh under the same conditions.

Which battery technology is used for this product?

This battery uses Lithium Iron Phosphate (LiFePO4) technology. This chemistry is known for its robustness, long lifespan, and tolerance to undercharge operation modes, thereby extending useful life even with partial recharges.

Does this battery require an external Battery Management System (BMS)?

Yes, an external Battery Management System (BMS) is required for the protection of this battery. Although it includes cell balancing and monitoring, the BMS manages load disconnection if cell voltage drops below 2.8 V and charge shutdown if cell voltage exceeds 3.75 V or in case of extreme temperature.

Can I connect multiple of these batteries in series or in parallel?

Yes, these batteries can be connected in series, in parallel, or in series/parallel. This allows you to build a battery bank for 12 V, 24 V, or 48 V systems.

What is the maximum number of batteries I can use in a single system?

You can integrate a maximum of 20 batteries in a single system. This allows reaching a maximum energy storage capacity of 102 kWh for 24 V and 48 V systems.

What are the dimensions and weight of the battery?
