    Pulse width modulation. You can feed the motor full power but the bats will see an average which will be under 30 A.

    OK, you guys are speaking a foreign language to me. I can design and fabricate almost anything mechanical, but electronics... UGH!! The good news is I have an Electronics Technician in the family. I will pass your suggestions on to him and see if we can implement them. If we can't program this controller to do what we need I'll just have to learn to use a "soft touch" on the throttle and keep an eagle eye on the ammeter when I'm accelerating.

    I ran my second race with the Lithium batteries on December 14. It was our annual "Speed Dash" event where we suspend the one-hour race length and go for only 20 minutes. The difference is we don't have to conserve battery power; we can run "balls out" for the duration. The course for this race was the quarter-mile oval (around the football field) at Brandon High School.

    I'm still learning how to program the controller, but it went fairly well this time. I was no competition for Cliff Rassweiler who's been running in Advanced Battery class for a couple of years, but I did manage a second place finish in both races which gave me a second place trophy for the day. I turned 39 laps in the first race and 42 in the second race for a total of 81. The third place car turned 79 laps. I'm learning...
