I have been doing some shopping for EV parts on various sites;
All the above are good links for motors and other ev parts. All their prices are pretty much the same.
The above are good links for lithium ion batteries.
I think I am going to go with electric motorsports because they are pretty much the same price as every other company (plus or minus $100) and they are right here in my backyard. So if I have any problems I can go straight to them.
