I have moved this from the build page to make it easier for doing a conversion using Nissan Leaf parts to find:
We are a business located in Gothenburg, Sweden that are focusing on making EV conversions simple. We offer an all in one solution. The Resolve controller makes EV conversion possible by using the motor, inverter, charger and battery pack from Nissan Leaf models from 2014-2017. By using the Resolve controller you don't have to integrate different systems or program yourself. The only thing that is required from the user is to wire the major drivetrains together. If you have any questions regarding our solution don't hesitate to ask below or email us on firstname.lastname@example.org.
