I like so many people out there would love to do an EV conversion but are not electrically savvy. Its easy to get overwhelmed with all the info and many hours of YouTubing/surfing for info.
For me, I am very mechanically inclined and can get on fine with a basic relay. Ive built many cars from the ground up and do all the mechanicals and paint....ect. Anyway there must be many like me out there that have the same questions. I'll just name a few that come to mind now and im sure it will bring on more questions later.
Cost is a factor, my first time Id like to start with a conversion that is relatively easy and modestly powerful. So Im thinking going with a Nissan Leaf. Open to a Tesla swap but cost I think will be triple or more? That would knock it off my list.
Should I start with a donor car Gen2 or if cost is close enough go for Gen3? Is an inverter board made for the Gen3 yet?
Can I think of the openinveter board as a "stand alone controller" as in it takes just the needed inputs to run the motor (similar to putting a Chevy LS stand alone ECM and harness in an old muscle car). So then charging battery and a/c... would also be stand alone systems also?
I think a 2014 Leaf had 80KW motor? what do gen3 motors have (quick Google search next

I'll have more questions for sure but just wanted to get these out there. Also I leave tomorrow until Wednesday so won't reply until then.
