I am an owner of parts of once was a 2014 Nissan Leaf. I have to say i have never driven a leaf nor currently looking to buy one. I do however have a 1980 Toyota Pickup that has a worn out engine that i am planning on replacing with the em57 motor/inverter/dc dc converter and parts of lithium battery pack (24kw). As I purchased just the modules and not the battery pack i have been forced to go service manuals/ forums to find missing parts and how they are connected. Having purchased just the engine stack and battery modules as do not have benefit of a whole leaf project car from which i can reverse engineer. It has and continues to be a challenge but am learning alot!
