Snow Driving

We took the del Sol out for a drive today. All-in-all very good but the acceleration was very choppy and slow and after about 5 minutes at about 40 MPH the controller cut out. I pulled over and it wasn't hot to the touch. I've been warned about overheating with the Kelly KDH but it isn't a hot day (see the pictures below and notice the snow). I'm more than a little concerned that the Kelly controller is both underpowered and easily overheated.


It took 5 attempts to get up the drive way between the choppy startup and the summer tires on the slick snow. Since the car came with studded snow tires I'll have to put them on soon.

After contacting Kelly Controlls customer service they said the KDH14401A (144V/400A w/ Regen) was underpowered for the vehicle. They recommended an upgrade to the KDH15600B (156V/600A). The A models are 7" while the B models are 11" and the web site says the B's are a newer design. I'm hoping that will take care of this problem.
