want a new controler

[coolhandcountry]

I got question. I see the more cell controllers have a limit on revs. I want to know if someone has a controller with out the low limits. I like to get some rpms out of the motor. The amperage shouldn't have to be that high. Motor is only rated at 74 amps. I like to try some more cells. Have a need for speed. :) LIke to try about 24 cells or so.
