Kudos! This is exactly the thread I wanted to find for 6-8 months! I have collected the motors, batts, vehicles for a motorcycle and a car, but no controllers.

I will build some myself if you have not done a group-buy or a kit soon. Either way, Thank you and keep it up!

P.S. Ever thought about the solid-state "peltier device" cooling chips for temp control? They move heat efficiently for little portable drink coolers. I usually see them at Goodwill for about seven dollars.

Basically done with the power section (Only one more tiny thing).


I can get about 15 more controllers out of the left over silver conductive epoxy (cold solder)! Ya! It doesn't take much.


Part of the way done with the power section. One more bus bar to attach!


That blue thing is the current sensor!


Notice the backing of the mosfets/diodes, which electrically insulates them from the heat spreader.


Blah blah blah, more pictures.


With Ben's heat sink! yaay!


The M- side. Don't worry, after the box, only one inch of bus bar will be visible.


The capacitor side, with the gate resistors soldered. A single wire will connect the control board to the gate resistor string. Black box, anyone??? ya!


Sorry Ben. slight mod necessary.

Awesome work. You have an excellent ability to physically build stuff. I can design and theorize all day, but i'd be really worried about putting a hole in the wrong spot on an expensive copper bar!

Make sure you wear safety goggles and gloves when you first power up this beast... who knows what might pop or heat up a couple hundred degrees.

Thread name change might be needed.

I'm sorry but this design, this functionality, this effort and support is FAR from cheap. Inexpensive yes, cheap no.
