Technology, patent registration and design
Our battery systems are based on state-of-the-art, long-lasting LiFePO4 cells. They are designed to combine a multitude of advantages while being extremely space-saving and economical. The smaller versions (12V/24V kits) are frequently used in campers, motorhomes, balcony power plants, boats, forklifts, and tiny houses. Our larger versions (48V kits), on the other hand, are ideally suited for conventional PV systems, forklifts, boats, and aerial work platforms. The higher energy storage capacity allows large appliances and entire households to be powered independently by the battery(ies) for several days or even weeks. Increasing the power and capacity is very easy by simply connecting identical batteries in parallel – even as a retrofit.
Our battery systems are complex to develop and have undergone extensive testing. Therefore, they are legally protected by various forms of protection. These include a patent application, several utility models, and the optical appearance (design/registered design). Details and sketches from the patent application are shown below as examples.
Advantages
Our battery systems consist of several High-performance cells together, which provide high cycle stability and thus a long service life of almost 8000 charging cycles can guarantee this. LiFePO4 cells They are considered the safest and most economical battery option on the market – and for good reason:
- Their compact size and weight, reduced by up to 70% compared to other batteries, make them the ideal storage solution in a wide variety of uses. 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 which occurs with older batteries.
- LiFePo4 cells are intrinsically safe, meaning they do not ignite themselves and do not leak.
- LiFePO4 batteries They are among the most modern lithium batteries. Due to a high number of cycles, the lifespan of LiFePo4 batteries is exceptionally long.
- LiFePo4 batteries are not only significantly cheaper and therefore more economical compared to lithium-ion batteries, but also have a higher cycle stability.

Below we show some example sketches.
This diagram shows the 12V 280Ah variant of our battery system. It represents the basic structure of our classic battery system. It consists of four prismatic LiFePO4 cells, two high-performance plastic end plates, a battery management system, tension straps, insulating washers, and a variety of integrated features such as strap guides and fasteners.

One of the advantages of our battery system is its flexibility and scalability. Significantly larger battery systems can be easily and compactly constructed from the basic components. Below is an example of a 48V 280Ah kit. It consists of 16 cells, with 8 cells installed per row. This results in a very compact design with a stored energy of 14.3 kWh.

Intended uses
Our products are versatile and have a wide range of applications. Thanks to the shared basic structure of the different battery systems, cells can be easily added, thus increasing the battery's power, voltage, and storage capacity. The compact design of the LiFePO4 batteries allows them to be used in a variety of locations and for diverse purposes.
Our LiFePO4 battery kits can be used, for example, as mobile power or energy storage systems. This makes them the perfect basis for an emergency generator that guarantees your continued power supply during power outages, or a mobile battery that provides power for extended camping trips.
But not only for power outages or mobile applications, but also for feeding in photovoltaic systems Our LiFePo4 batteries can be used in balcony power plants or solar power plants. Further information on this topic can be found in our blog article How PV systems with LiFePo4 batteries work.
Here you can see our complete 12V 280Ah LiFePO4-based battery kit, which includes all necessary components. It consists of four EVE Grade A+ cells, a BMS, our heavy-duty mounting kit, and other functional accessories. In addition to the technical specifications, another important aspect is our very detailed, German-language instruction manual. This manual describes every step of the assembly process in detail.
cells
All our EVE Grade A+ cells are Tested and with the specified storage voltage. All cells are genuine LiFePO4 cells from the brand manufacturer EVE with a laser-engraved, complete QR code. Our customers do not need any special tools; they can put the cells into operation directly using the assembly instructions for one of our battery systems.
The Cells in different The batteries can be arranged in single or double rows. This allows for maximum flexibility in battery dimensions. This is guaranteed in order to adapt the space requirements to the respective installation situation.
Battery Management System
Our Daly BMS is one of the most advanced battery management systems with a wide range of functions. The BMS can be configured via smartphone, and the state of charge and other parameters can be viewed via the free app.
Heavy Duty Fixing Set
The Heavy Duty fixing set holds our battery kits together and is unique in its design. The set, consisting of black painted front and back panels, acts as the outer casing for the battery when used with other accessories.
The design is protected by the European Union Intellectual Property Office.
