Does anyone know what the relationship of the pot reading and the current
out of the controller? Is it linear? For example, the pot is set at 1k
ohms, and 100 amps is delivered to the motor. The pot is at halfway, at
2.5k ohms, and the current is 250 amps. The full 5k ohms, and 500 amps. Is
this correct?
Then the question comes, as another way to limit the current. Can I
parallel a resistor that would limit the resistance of the pot. Say I don't
want more than 100 amps, so I put a 1k ohm resistor in parallel. Would this
work? If so, what would the power of the resistor need to be? Quarter
watt? Half?
And lastly, if the current to the motor is 100 amps, is that what I am
pulling from the batteries?
I appreciate any suggestions.
