Lithium Battery with LiFePO4 Technology

This battery rack is equipped with 16 modules that deliver a capacity of 420 Ah and a total energy storage of 22.2 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 providing continuous 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.

Perfect Scalable Energy Solution

Our Lithium Power Plus modular battery racks are beautiful scalable energy solutions that ensure high-performance. This innovative construction of the battery modules in their housing leads to a longer service life, improved reliability, and the delivery of consistent power. The balanced charging and discharging of each module, a complex process with individual modules and wiring, is regulated from the design phase.

Custom Design

In addition to this version and the other standard models, much more is possible. We design your enclosure custom, with or without integrated DC distribution and one or more Whisper Interface Box battery management systems. Want to know which configuration suits your situation? Inquire about the possibilities.
