Our battery systems are based on state-of-the-art and very durable Lifepo4 cells. They are designed to combine a variety of benefits while being extremely space-saving and economical. The smaller variants (12v/24v kits) are often used in campers, mobile homes, balcony power plants or tiny houses. Our larger variants (48v kits), on the other hand, are excellently suited for classic PV systems. Due to the higher stored energy, large consumers and entire households can be supplied independently for several days by the battery.
Our battery systems are legally protected by various types of protection. This includes a patent application, several utility models and the design (registered design). Details and sketches from the patent application are listed below as examples.
Our battery systems are made up of several high-performance cells, which can guarantee high cycle stability and thus a long service life of almost 6000 charging cycles. Lifepo4 cells are considered the safest and most economical battery variant on the market - and for good reasons:
A patent application, utility model and design protection (design patent) exist for our battery systems. Below are the certificates of the 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 supporting element and a battery cell with this supporting element.
The protective rights can be found at the German Patent and Trademark Office under the following file numbers.

In the following we show some sketches as examples.
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, tension belts, insulating washers and a multitude of built-in functions such as belt guides and attachments.

One of the advantages of our battery system is its flexibility and scalability. Significantly larger battery systems can also be produced very easily and in a space-saving manner from the basic components. Below is therefore an example of a 48v 280Ah kit. It consists of 16 cells, of which 8 are installed in each row. This results in a very compact structure with a stored energy of 14.3kWh.
Our products can be used flexibly and have a wide range of applications. Due to the same basic structure of the different battery systems, cells can be flexibly added and thus the performance, voltage and storage capacity of the battery can be expanded. Due to the compact design, the LiFePo4 batteries can be used in a wide variety of places and for a wide variety of purposes.
For example, our LiFePo4 battery kits can be used as mobile power or energy storage. As a result, they provide the perfect basis for a backup generator that will continue to guarantee your power supply during power outages, or a mobile battery that will provide you with power on longer camping trips.
Our LiFePo4 batteries can not only be used in the event of power failures or mobile applications, but also to feed in photovoltaic systems or balcony power plants. You can find more information on this topic in our blog articles How PV systems with LiFePo4 batteries work.
Here is our complete 12v 280Ah kit on a Lifepo4 base, which includes all the necessary components. It consists of 4 EVE Grade A+ cells, a BMS, our heavy-duty fixation set and other functional accessories. In addition to the technical data, another important aspect is our self-written and very detailed instructions in German. It describes each step of assembly in detail.
Depending on the desired capacity, voltage and performance range, a different number of cells can be used to construct a battery.
The cells can also be arranged in different ways, i.e. in one or two rows. This guarantees that the battery dimensions can be designed as flexibly as possible in order to adapt the space required to the respective installation situation.
Our Daly BMS is one of the most modern battery management systems with a multitude of functions. The BMS can be set via smartphone and the charge status and other parameters can be viewed via the free app.
The Heavy Duty fixing set holds our battery assembly kits together and is unique in its design. The set, consisting of 3D-printed front and back panels, ratchet straps, screws and insulating washers, together with other accessories, acts as the outer shell of the battery.
The design is protected by the European Union Intellectual Property Office.
