    The controller is set for torque mode, so throttle percent = torque percent. The RPM can very easily spin out of control if there's no load on the motor. Once it's installed in a vehicle, it'll feel...

    The Sevcon should be the only thing connected to the contactor. The Sevcon controls it. You just need to give pack voltage to pin 1, KSI.

    Wire per the manual.

    Next, FS1 needs to be active prior...

    I'd aim for 100V and 500-550A if you can. Nice sweet spot with this motor/controller combo.

    The DVT Programming kit can allow some parameter changes on the fly easily.

    I don't know of other controllers that are tuned with that motor besides the Sevcon Gen4 series. The Size 6 is 550A 2 minute, 660A peak for 10seconds. That ought to do well for 660ft! That's at up to...

    What motor is it?

    Do you have controller already?


    Usually the higher voltage, the higher it can go in the RPM range. But the higher current, the higher torque.

    Haven't used one of those before. You're right at the top (84V peak on 4.2v a cell and 20 cells), so if you add any later, you'll have to get another DC-DC.

    The thing I'm more concerned about, is...

    I don't currently stock them, but I can get just about anything you need.

    No experience with the Domino. Just Magura. I think the Zero I rode had a Magura. It was just fine.

    I think the Magura feels cheep, and it's not very springy, and the throw is way to long. I never tried domino, but it sounds shorter throw and better feel.
