Awesome. Most of this is new to me  ...  so what sort of money do you have to pay for a mainstream 48V @ 40A controller? Is that Litz wire in the inductor  ...  or something you combined yourself. I kept a heap of old Panasonic Inverter Microwave transformers for the Litz wire on them  ...  though don't think I've ever unwound one to find out just how much is on each one. I'll be following this thread with interest.   Cheers,  Roger
