Victron Lithium LiFePO4 Battery 25.6V 100Ah Smart
The Victron Lithium LiFePO4 Battery 25.6V 100Ah, phosphate, iron and lithium; connects in series and in parallel with excellent efficiency.
Description of the Lithium LiFePO4 Victron 25.6V 100Ah Smart Battery
The Victron 25.6V 100Ah Smart LiFePO4 Lithium Battery is a 25.6V monoblock battery that has a capacity of 100Ah and a stored energy of 2560Wh. Thanks to its sealed design, it does not require any maintenance. They are the safest lithium iron phosphate batteries on the market and have a rated voltage per LFP cell of 3.2V (lead-acid: 2V/cell). Therefore, this 25.6V LFP battery consists of 8 cells connected in series.
One of the biggest advantages of these batteries over lead acid batteries is that they do not need to be fully charged. Its lifespan will even improve if it is partially charged instead of fully charged. Other advantages are wide working temperature range, excellent cycling performance, low internal resistance and high efficiency.
This battery can be used in various applications, especially off-grid, solar and/or wind applications, but also for the most demanding applications. It has one of the full cycle energy efficiencies (discharge from 100% to 0% and recharge to 100%) of 92%, one of the highest in the sector.
The charging process of lead-acid batteries becomes particularly inefficient when the 80% state of charge is reached, resulting in efficiencies of 50% or even lower in solar systems where reserves are needed for several days (batteries). Operating between 70% and 100% load). In contrast, an LFP battery will still achieve 90% efficiency under lightly discharged conditions.
With dimensions of 197 x 650 x 163 mm and a weight of 28 kg, it is an ideal battery for areas where not much space can be occupied.
In addition, through the Li-ion app you can monitor cell voltages, temperatures and alarm status. Very useful for locating a (possible) problem, such as a cell imbalance.
Installation of the Lithium LiFePO4 Victron 25.6V 100Ah Smart Battery
These LFP batteries have integrated cell balancing and control. Up to 5 batteries can be installed in parallel and up to four 12V or two 24V batteries in series, so that a bank of 48V batteries up to 1500Ah can be configured.
Cell balancing/monitoring cables can be daisy-chained and must be connected to a battery management system (BMS). This system can:
1. It can generate a pre-alarm whenever the voltage of a battery cell falls below 3.1V (adjustable between 2.85V and 3.15V).
2. Disconnect or turn off the load when the voltage of a battery cell falls below 2.8V (adjustable between 2.6V and 2.8V).
3. Stop the charging process when the voltage of a battery cell rises above 3.75V or the temperature rises above 60 °C.
