Our battery systems are based on state-of-the-art and very durable LiFePO4 cells. They are designed to combine a variety of advantages while being extremely space-saving and economical. The smaller versions (12V/24V kits) are often used in campers, mobile homes, balcony power plants, or tiny houses. Our larger versions (48V kits), on the other hand, are suitable terrific for conventional PV systems. Due to the higher stored energy, large consumers and entire households can be supplied autonomously by the battery for several days.

Our battery systems are legally protected by various types of protection. These include a patent application, several utility models, and the design (design patent). Details and sketches from the patent application are listed below as examples.

Advantages

Our battery systems consist of several High-performance cells together, which ensures high cycle stability and thus the long service life of almost 8000 charging cycles can ensure. LiFePO4 cells are considered the safest and most economical battery variant on the market – and for good reasons:

• Their compact size and their weight, which is up to 70% lower than other batteries, make them the ideal storage in a wide variety of applications, from campers and boats to powering entire houses.
• LiFePo4 batteries can be fully discharged and their capacity fully utilized. There is no memory effect like that found in older batteries.
• LiFePo4 cells are intrinsically safe, meaning they do not ignite or leak.
• LiFePo4 batteries are among the most modern lithium batteries. Due to the high number of cycles, the service life of LiFePo4 batteries is extremely long.
• Compared to lithium-ion batteries, LiFePo4 batteries are not only significantly cheaper and therefore more economical, but also have a higher cycle stability.

Below we show some example sketches.

This sketch shows The 12V 280Ah version of our battery system. This is the basic structure of our classic battery system. It consists of four prismatic Lifepo4 cells, two end plates made of high-performance plastic, a battery management system, tensioning straps, insulating washers, and a variety of built-in features such as belt guides and fasteners.

One of the advantages of our battery systems is their flexibility and scalability. Even much larger battery systems can be easily constructed from the basic components, saving space. Below is an example of a 48V 280Ah kit. It consists of 16 cells, with eight cells installed per row. This creates a very compact design with a stored energy capacity of 14.3kWh.

Purposes

Our products are flexible and have a wide range of applications. The common basic structure of the different battery systems allows for flexible cell addition, thus expanding the battery's power, voltage, and storage capacity. Their compact design allows LiFePo4 batteries to be used in a wide variety of locations and for a wide variety of purposes.

For example, our LiFePo4 battery kits can be used as mobile power or energy storage. They provide the perfect foundation for an emergency power generator that ensures continued power supply during power outages, or a mobile battery that provides power for longer camping trips.

Not only in the event of power outages or mobile applications, but also for feeding photovoltaic systems or balcony power plants our LiFePo4 batteries can be used. For more information on this topic, see our blog article How PV systems with LiFePo4 batteries work.

Here is our complete 12v 280Ah kit on a Lifepo4 base, which contains all the necessary components. It consists of 4 EVE Grade A+ cells, a BMS, and our heavy-duty fixing kit. as well as other functional accessories. In addition to the technical specifications, another important aspect is our very detailed German instructions, which we wrote ourselves. These describe every step of the assembly process in detail.

cells

Depending on the desired capacity, voltage and power range, a different number of cells can be used to construct a battery.

The Cells in different arrangement, i.e. in one or two rows. This allows for the most flexible design of the battery dimensions be guaranteed in order to adapt the space requirements to the respective installation situation.

Battery Management System

Our Daly BMS is one of the most modern battery management systems with a wide range of functions. The BMS can be configured via smartphone, and the charge level and other parameters can be viewed via the free app.

Heavy Duty Fixing Set

The Heavy Duty Fixing Kit holds our battery kits together and is unique in its design. The kit, consisting of 3D-printed front and back panels, tensioning straps, screws, and insulating washers, acts as the outer shell of the battery when used in conjunction with other accessories.

The design is protected by the European Union Intellectual Property Office.
