Paul, I've noticed two things lately - you are pulling people out of the EV woodwork into this forum and you're giving excellent answers to technical details!

When I saw someone mention the reason for the 15/1.5khz switch i was gitty that I could respond, but you beat me to it. The answer is - THIS CONTROLLER IS BETTER!!!! No silly 500 amps at 15% throttle! That's just silly! We do 15% of 500 amps at 15% throttle! ALWAYS! Here's the sweet part... if a duty of ONE on the PWM would generate an overcurrent, then this controller will actually pulse from 0 to 1 to 0 to 1 watching the current and maintaining it at a very low value. Silly "professionals" they need to learn how its done by the EcoModder hacks! Open Source FTW!
