When was Dan-Tech Energy founded, and where are you based?
The company was founded more than 25 years ago in Tel Aviv, Israel. We have had a second entity in Berlin for around 15 years, with both an office and a fully certified production line.
What do you specialize in and why?
We specialize in the development of tailor-made battery packs, particularly for drones and robotics, but also for other applications such as medical devices. Our key strengths are speed and technical expertise: customers often receive a fully functional sample within just four to six weeks. This makes us significantly faster than the industry average. While larger manufacturers are often only interested in large orders, we offer individual, customer-oriented solutions for small to medium quantities, starting from a sample development. Production can be scaled up quickly if required, from a few test samples to thousands of units per year. We particularly enjoy collaborating with small and medium-sized companies and rely on close cooperation to meet their specific requirements.
What challenges and special requirements are there in battery production?
Drones and robots often have special form factors and require batteries with customized performance parameters – for example, high energy density with limited installation space or particularly high current output in the first few seconds of operation. To achieve this, we use high-quality cells from renowned manufacturers and develop solutions that offer both high performance and efficiency. We are also working on new cell technologies from innovative manufacturers to be able to offer our customers state-of-the-art solutions with even higher energy density.
Not all manufacturers of autonomous systems are also experts in battery management. Do you also offer consulting?
In addition to technical development, we naturally also offer comprehensive advice, especially for customers who are less familiar with battery technology. Our experts support them in selecting the right cell chemistry (e.g., lithium-ion or LiPo), conducting run-time analyses, and integrating the battery into their existing systems. We also advise on the appropriate charging infrastructure, as using the wrong charger can significantly reduce the lifespan of a battery.
Trust in products often comes from certifications. What is the situation with you?
Our batteries are designed to comply with all relevant international certification standards, depending on our clients' specific requirements. One of the most important is the UN 38.3 certification, which ensures the safe transport of lithium batteries. To streamline this process, we’ve established well-defined workflows that help ensure a smooth and efficient path to UN 38.3 certification. Additionally, our Berlin production facility is ISO 9001:2015 certified, ensuring consistent quality management. We also offer comprehensive support for logistics, recycling, and compliance with evolving legal regulations.
Following your success at XPONENTIAL Europe 2025, will you be back again next year and if so, what will you be presenting there?
Absolutely. We had a fantastic experience at XPONENTIAL Europe 2025. The event provided us with valuable networking opportunities and allowed us to connect with both existing and potential partners from across the drone and robotics industries. We're definitely planning to return next year. At the next XPONENTIAL, we’ll be showcasing advancements in high-density battery technologies, new smart BMS features, and probably several custom battery solutions developed in collaboration with our clients.
