I am going to be purchasing the flex a lite kit VSC it's kind of pricey, but for the ford electric fans it helps with voltage spikes by using pulse width modulation to start them and little boosts of power at a time to get them running until finally feeding all the power once the fan is moving to contend with the start up draws. It also varies the fan speed between 60-100 percent based on a 10degree scale in temperature rise so the fans don't always necessarily run 100 percent to help with p draw as well. That's te way ill be going.
