    Beware the pololu and BB-VNH3SP30 are very fussy when running at 24v , if input power surges up they will immediately shutdown.

    Found this on Pololu forums: "While VNH3SP30’s over-voltage shutoff doesn’t activate until 36 V, in our experience, shoot-through currents make PWM operation impractical above 16 V".

    Played with both on 24v , just letting ya know what I found with them, My fav was the Sabertooth , with a fan over it didn't miss a beat, just not a cheap option, had to run the 25x2 on it thou.
    Im sure a Chinese unit exists that can keep up with them. Well I hope there is.

    in my case unfortunately the sabertooth are pretty expensive it would become cheaper to use a worm gear instead the planetary gear in combination with a strong 12v motor like the winches (750W and more) and the cheap but approved MMs.

    I have an Arduino uno and 3 BTS7960 IBT2 40A , how to manage connect all the drivers wires to one Arduino? is the pins enough for 3 drivers?
