I ordered the standard brushless 6" fan kit from Radiant Charge company for about $90. And I ordered another set of circuit parts for my 3-pole generator/motor kit for $10, I still want to get it going. Dan said that they are getting better transistors now and are drawing up a different circuit diagram to fit the new transistors. Also they are selling three more poles (for 6 total) to snap into the generator 3-pole kit if you want to hop it up. I didn't order it.
I just think that the 6" fan kit has bigger component parts and will be easier to solder up. I bet that with the curved factory magnets that it has more power efficiency also. We'll see.
I tried charging up some small lithium batteries with my small Radiant charger and it actually took the voltage down from 2.5 volts to 1.5 volts. They admit that it doesn't work on Lithium batteries for some reason. But I wanted to try it anyway.
