I’m planning on a 144v pack voltage to use the Motor in the upper end of it range, giving us maximum power / acceleration potential, especially given the “brick” natural of the aerodynamic profile.

From similar on line projects I found the Curtis 1231C is a very popular choice and also some builders are using the Kelly Controller which seems to be a newer entry on the market

The Curtis controller is a basic controller and is a little more expensive than the Kelly.

Conversely the Kelly controller has many options and external connections and is a little cheaper.

I like the Curtis simple and easy to use, but the geek in me wants all the status ~LEDs and serial ports of the Kelly controller. At the end of the day the most important thing is reliability and safety. For safety I’m leaning to simple sounds better – less things to go wrong. I will spend some more time researching both models and make the call here.
