Concept
Daurema designs and manufactures bicycle batteries and household batteries, using reused lithium-ion cells, seamless, easily repairable and reconditionable.
The battery design is designed for assembly, disassembly, repair and reconditioning. The different parts, such as the battery pack, the BMS, or the connectors, are nested and clip-on like Lego bricks.
In addition, Daurema also produces 3D printed wedging parts in order to have ergonomics and perfect interlocking of the different elements of the Lihtium battery.
This is a major innovation in the assembly of Lithium-ion batteries. To date, most lithium cells are connected together by strips of nikel soldered on the two poles of the cell. During repair or dismantling, these welds must be pulled out one by one, with pliers, while the cell poles must be polished. This results in human labor time and high energy costs.
This is why Daurema has developed, for some of its battery models, a system for bringing the cell poles into contact with PCB plates (printed circuits) on which micro-springs are attached. These two plates are screwed together, with the cells in between. So, if there is a repair to be made, simply unscrew the plates, change the few defective cells, then screw the whole thing back together. The repair takes less than 30 minutes, and it is possible to carry out this operation many times, over several decades, while keeping the same functional parts.
Ultimately, this system saves time, saves money for the customer, extends the life of the batteries and the cells that make them up, and significantly reduces CO2 emissions emitted by the battery over its entire life cycle. .
Daurema has developed different battery models:
- For micro-mobility: small battery with 50km range specially designed for frame bags
- For long or cargo mobility: 100km range batteries, with standard Hailong shell and shell support designed to take the place of the water bottle holder, without modification on the bike for grip
- For heavy cargo mobility: battery with 150km range, with handle, to be placed in the cargo bike trailer. A fastening system is provided for perfect alignment
- For the home: this battery has the same design as the heavy cargo battery, and allows you to store the energy produced by the solar panels, then release it to power your home. This battery is compatible with most hybrid inverters on the market. It can be carried by hand, and it is possible to connect several in parallel

Our DNA
At Daurema, each battery we recondition is one step closer to a future where technology and ecology coexist harmoniously
A BATTERY WITH POSITIVE ECOLOGICAL IMPACT
Environmental impact
Adopting our reconditioned batteries is a significant step towards a more sustainable future. By switching to recycled lithium-ion cells, we significantly reduce electronic waste and the carbon footprint associated with the production of new batteries. This recycling process not only preserves natural resources, but also helps reduce pollution linked to the extraction and processing of raw materials. Every battery we put back on the market is a victory for the environment, illustrating our commitment to a healthier planet
Future prospects
At Daurema, our vision goes beyond the present. We are committed to continuous research for innovation and improvement of our products. In the future, we plan to expand our range with even more efficient and environmentally friendly energy solutions. We are also exploring new collaborations and partnerships to expand our ecological impact. Our goal is to stay at the forefront of battery technology, while actively contributing to a more sustainable future.
