How We Work

Step One

Project Scope

We meet or have a video call to gain insight into your product and battery requirements. This will enable us to discuss if you need one of our standard solutions or a custom battery, with design and materials that fit your functionality and fulfillment needs.

We design the enclosure/cell layout and source materials according to the project scope. We assemble a prototype, test it internally and ship it to you for testing. If you are happy we move to the next step! If changes are needed we repeat the process.

This is a paid process and depending on the battery size it can be between ~5000 PLN. If we end up working together, the price of prototyping is discounted in the first order.
