people do business with leo all the time. they seem to me to be more reputable because they do offer warranty service to repair the controller if it fails in 6 months.
but the sine wave type of commutation has to be difficult to implement or more would be making these types of controllers. i assume the uprocessor has some type of DAC to create the sinusoidal profile in current commutation.
i really think this is extremely beneficial to the mosfets and use less battery power for the same amount of work done as the controllers using sawtooth type commutation.

I got my Hua Tong in yesterday. Label says 2012/8/20... new generation? I don't see a label in the bottom left like on the previous pictures, so not sure what model this one is.
Question for folks that have one of these, where is the X pad on the board? I see a "XS" pad, is that it?
Also the Brake Hi plug only has one wire in it, how would I wire the X pad up to the brake? I'd like to get either Regen or Wheel Lock working with the brake. I desperately need more braking power :|
Thanks for any help. Pics attached.
edit: Found it! much easier to find on the back side of the board
I'll post back with results later on.

That's a newer board. Several people got that board, but I don't know if they ever found where regen was. You can experiment with it. Regn on mine is accomplished by running the X pad to ground through the ebrakes. If you want brake-hi to work, run it through the ebrakes back to positive battery power. For either to work you have to have LVC set properly. Default LVC is 62V and supports up to ~78V battery power. Works perfect with 18s lipo. It quit working when I went to 24s until I changed LVC to 84V. I'm pretty sure there's a thread about the newer controller board here somewhere. You'll just havce to find it to see if there's any info in it you can use.

Woo got the regen working on the newest Hua Tong 72V 1.5kW 40A controller! Thanks for your help Wes. Ran a wire from X to GND and on the other end took one of the yescomusa controller e-brake connections and soldered that to the X to Gnd line. Works great and does increase the voltage pretty nicely with great stopping power.wesnewell said:
I'm running 20s lipo which runs between 74V low up to 83V high. Worked fine without changing any LVC on the controller.

pin 2 reverse
pin 4 wheel lock
pin 17 speed 1
pin 7/19 open speed 2
pin 19 speed 3
14 extra slow - don't no what this is for reverse?
pin 11 kills power to wheel
will update when i have had a look at the rest, i am hoping to sort out a variable regen
