Our battery systems are based on state-of-the-art  and very long-lasting Lifepo4 cells. They are designed to combine a variety of advantages and are extremely space-saving and economical. The smaller versions (12v/24v kits) are often used in campers, mobile homes, balcony power stations or tiny houses. Our larger versions (48v kits), on the other hand, are suitable  terrific  for classic PV systems. Due to the higher amount of stored energy, large consumers and entire households can be supplied independently 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 which ensure high cycle stability and thus the long service life of almost 8000 charging cycles 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 range of applications, from campers to boats to supplying electricity to entire houses.
• LiFePo4 batteries can be fully discharged and their capacity fully used. There is no memory effect as occurs with old batteries.
• LiFePo4 cells are intrinsically safe, which means that they do not ignite or leak.
• LiFePo4 batteries  are among the most modern lithium batteries.  Due to a 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.

patent application and  utility model

A patent application, utility model and design protection (design patent) exist for our battery systems. Below are the certificates of  Utility model for the device for fixing prismatic battery cells, wiring cover and modular battery system with this wiring cover, protective cover and modular battery system with this protective cover and  support element and a battery cell with this support element  to see.

  

 

The protective rights are  at the German Patent and Trademark Office under the following file numbers.

The design is also protected and can be found at the German Patent and Trademark Office under the following file number.

Below we show some example sketches.

This sketch shows  the 12v 280Ah variant of our battery system. This is the basic structure of our classic battery system. It consists of 4 prismatic Lifepo4 cells, two end plates made of high-performance plastic, a battery management system, tensioning straps, insulating discs and a variety of built-in functions such as belt guides and fastenings.

One of the advantages of our battery system is its flexibility and scalability. Much larger battery systems can be manufactured very easily and in a space-saving manner from the basic components. Below is an example of a 48v 280Ah kit. It consists of 16 cells, 8 of which are installed in each row. This creates a very compact structure with a stored energy of 14.3kWh.

purposes

Our products can be used flexibly and have a wide range of applications. The same basic structure of the different battery systems means that cells can be added flexibly, thus increasing the performance, voltage and storage capacity of the battery. The compact design means that LiFePo4 batteries can be used in a wide range of locations and for a wide range of purposes.

For example, our LiFePo4 battery kits can be used as mobile power or energy storage. This means they provide the perfect basis for an emergency power generator that will continue to guarantee your power supply in the event of a power outage, or a mobile battery that will provide you with power on 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 work with LiFePo4 batteries .

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, our Heavy Duty Fixing Set  and other functional accessories. Another important aspect, in addition to the technical data, is our own, very detailed German instructions. Each step of the assembly is described 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 the most flexible design of the battery dimensions  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 adjusted via smartphone and the charge level and other parameters can be viewed via the free app.

Fixation Set Heavy Duty

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

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