Innovative, responsible
battery solutions

With our highly flexible production setup, besides the possibility of manufacturing e-bike batteries, we offer to create tailormade, complex, and technically demanding battery solutions for the right industrial partner, meeting all customer requirements.


Four essential processes in the Viridus production to secure the highest quality:


The first step in our battery production begins here. The Sorting machine secures every cell works to our high standards.

Furthermore, it selects and sorts the cells so they have the same voltage (Y). and sort them in the same channel to pick from.

Welding Robot

When the battery pack is assembled, it goes through our Vision test system. Vision Test System assures that all cells are in the correct position before they go through the welding machine.

In the Welding machine, all battery cells are welded together. The welding machine makes this process five times faster than an average employee and secures a quality standard that is impossible to get on normal handcraft.

The process runs seamlessly, and all employees can operate the machine. By that, we secure high flexibility in our production.

Functionality Test – Nebula

Functionality Test: Nebula is the first test of the battery pack. The test takes only 20 seconds to run diagnostic on the BMS, Cells, and weldings.

These short tests will catch error codes on charging, discharging, and voltage in the

Aging Equipment

The last step is the aging process. The state-of-the-art equipment secures a high-standard test that runs for three days. The aging test gives us a complete overview of each battery and its performance.

The full diagnostic catches even the most minor errors. The Aging test is the final piece in our production that makes our batteries stand out in quality.

Battery Line

We have upgraded our battery assembly with a production line that can produce battery packs with a larger cell format, 21700. We look forward to being able to offer that to our customers. 

The cell format is distinguished by having more charging cycles and a greater energy density (more energy per volume) compared to the current 18650 designs.
