Our electric bike batteries are developed and tested in accordance with the European standard EN50604, which ensures the highest level of safety, reliability and compliance for lithium-ion batteries. So you can trust that your battery meets all the necessary requirements for worry-free use.
Industries in which we are present with our Li-ion battery systems: e-bikes, e-scooters and e-mopeds, robots, drones, e-haulers, e-scooters, e-mopeds, and ESS home storage.
Universal use
The single ECONO ELK battery allows you to swap between different bike models for greater flexibility.
Long lifetime
We use the highest quality Samsung and LG Li-ion cells and a smart BMS, which keeps the battery pack in excellent condition for years.
Smart BMS
An advanced control system (BMS) protects the battery from extreme conditions and communicates with the motor for an optimal user experience.
No memory effect
Econo batteries can be charged at any time, regardless of the charge level - there is no negative effect on capacity.
Our team is continuously upgrading our knowledge and developing batteries for the specific requirements of different applications - from electric bikes and scooters to specialised industrial solutions. With us, you can realise every power supply idea.
All battery development and production takes place in our company in Maribor. In-house production means faster and more reliable delivery, strict quality control and long-term customer support (inspections, software updates, service).
We provide the entire process of developing Li-ion battery solutions - from consultation and design, through prototyping and testing, to series production, certification and post-installation technical support. Each device requires its own approach - vehicles need performance, medical solutions need safety and industry needs robustness. Standard batteries do not meet these requirements.
We develop customised battery packs for you, where the voltage, capacity, design and protection are perfectly matched to your project. We build exactly what you need - without compromise.
We work with you to determine the optimal battery configuration for your needs and applications.
We present our services and options, and, depending on your needs, develop a project plan that brings together all the milestones from development to production. A well-laid foundation is the key to a long-term and constructive partnership.
Prototype development is closely linked to testing in the initial phase. Working and testing together gives you insight into the design of your prototype. This is the only way to develop the final prototype into a safe, high-quality and reliable battery pack. We make sure the battery meets your technical requirements and safety standards.
Optimising battery performance and integration into your system.
Certification and standards compliance - we ensure your battery meets all safety and quality requirements.
All our Li-ion battery systems comply with European and international standards (UN 38.3, CE, EN 50604, etc.). Each solution includes documented testing, component traceability and certification.
Mass production - once the prototype is approved, we ensure efficient production and delivery.
Our in-house production gives us full control over the quality of the battery packs we produce. It also provides us with easier organisation and increased production speed.
We guarantee fast and flexible delivery, perfectly matched to your transport and storage requirements.
We offer expert technical support and reliable service throughout the battery's life cycle. We closely monitor the entire product lifecycle to ensure top quality in both manufacturing and delivery.
The cooperation with Comtron provides flexible and certified Li-ion batteries (UN 38.3, CE, EN 50604) suitable for all project sizes. Our advanced manufacturing uses automatic cell welding and 3D printing. We can accommodate no minimum quantities and offer support in the certification of custom batteries.
Our batteries are ideal for small and large companies developing products such as electric bicycles, vehicles or devices that require Li-ion battery packs with a capacity between 300 and 2000 kWh. We are particularly suited for smaller companies or the development departments of larger companies looking for customised solutions for new projects.
We can be reached by email at info@comtron.si or by phone on +386 2 300 35 30. We are happy to discuss your needs and find the best solution.
Yes, EU legislation makes battery certification mandatory. Our standard batteries already have UN 38.3, CE and EN 50604 certification. For custom batteries, we offer expert support in obtaining the necessary certification.
Standard batteries use existing housings from leading manufacturers (Reention, SYR, Shanshan Plastics) for faster delivery. Custom batteries are custom designed with customised cells, BMS electronics and housing to suit your needs.
At Comtron, we do not have minimum quantities. We adapt to each customer, whatever the size of the order, and together we find the best solution.
The average development time for custom batteries is between 2 and 6 months, depending on the complexity of the project and testing.
We use high quality Li-ion cells from Samsung and LG. Our production includes automatic cell welding and 3D printing for precision components, laser engraving,...
From Slovenia, we offer faster delivery to neighbouring countries and ship to all EU countries, and even outside the EU by arrangement.
