I'm trying to decide on a Kelly controller now. I am going with six 85ah lead acid 12 volt batteries. I don't know the specs on the motor other than it is 7.5" diameter by 10.5" long with 8 brushes and weighs 65lbs. All I have to go on is that I also have a 7.5" by 12.5" motor that is rated at 353 amps so I am guessing the one on the Ninja will handle 250-300 amps. Does that sound reasonable? . I was thinking about the kd72300 or kd84300 in case I decide to squeeze one more battery in.
Here are the choices:
Series Motor Controller or Permanent Magnet Motor Controller
