Hello! I'm James and I have over 15 different Power Wheels vehicles and over 30 after market batteries. I had to learn much of this stuff through trial and error. Let's just say that I have blown my share of fuses! This is the course that I wish existed when I first got started. A course that didn't assume that I knew much, because I certainly didn't. I'm excited to introduce you to a hobby that both you and your children will love. Be safe out there!
