Help me choose a good affordable 72v controller for 5KW QS V3 Rear Direct Drive Hub Motor.

My options so far: Mobipus 72200, Kelly KLS7230S, Sabvoton 72200 (read bad things about Sabovoton).

Get a Nucular 24F. The QS hub motor power ratings are very conservative and can handle much more. Nucular is the new kid on the block with very good results.

The new PowerVelocity might also be a good candidate but not yet reviewed:

I'll second that. Go for the 24F nucular. well worth the wait. having used Sabvoton,APT, Infineons etc, the 24f is fantastic

Also going for the 24F nucular even if i never used one.
Votol em72150 for cheaper option. 200A battery, 370A phase. Unlocked. I am currently running 250A through one since some time.
