I wanted an electric SUV and wasn't impressed with any of the OEM options. I went with a Hyper9 because I needed to use Tesla modules to get the range I was looking for, and the voltages of the modules dictated that the Hyper9 was my best option. The goal of this project is to build a daily-drivable, reliable EV that has at least 150 miles of range. I've been keeping track of my progess on YouTube: https://www.youtube.com/channel/UCJ9hpFxka5utGt08fklUPRQ
The Hyper 9 motor has a standard bolt pattern that means it can be used with the CanEV adapter plate so mounting is easy. If I had more fabrication resources, I'd probably consider using a Nissan Leaf motor.
I used the SimpBMS for the Tesla modules (https://www.ebay.com/itm/363521708233).
Mounting the motor to the transmission took a while because of how precise the coupler fit on the transmission shaft. They had to be perfectly aligned for the motor and transmission to slide together. Making battery boxes has taken a lot longer than I've expected. This is by far the most tedious part of the project.
