Lithium Battery with LiFePO4 Technology

This battery rack is equipped with 4 modules that deliver a capacity of 105 Ah and a total energy storage of 5.5 kWh at a voltage of 48 VDC. Guaranteed highest quality thanks to LiFePO4 chemistry with primary cells. LiFePO4 stands for lithium iron phosphate and is also known by the abbreviation LFP. This is the safest lithium technology offering a longer lifespan, improved discharge, and charging efficiency. This makes the battery perfectly suitable for maritime applications. Additionally, lithium is completely maintenance-free and lighter in weight compared to other technologies. Want to know more? Everything about this lithium technology and applications can be found on the lithium battery information pages: part 1 and part 2.

Optimal Scalable Energy Solution

Our Lithium Power Plus modular battery racks are beautiful scalable energy solutions that ensure high-performance. This construction method of the battery modules in an enclosure provides a longer lifespan, higher reliability, and the delivery of consistent power. The design process includes carefully balancing the charging and discharging of each module, which poses a challenge with individual modules and their wiring.
