OK... I'm building an E-kart to go at least 60mph. I bought an Alltrax SR72450 controller, sw202 selenoid, 5k throttle today. The problem is I will have to mount everything after receiving it which will cost more money in materials. Then I came across a Curtis controller already mounted on a heatsink plate, neatly done with copper bars and with all components needed on eBay for under $600 (link listed below). I'm wondering which controller would be better for my setup and is it worth keeping the Alltrax and mounting everything up or return the Alltrax controller (which costed me more) and buy the Curtis controller? Will I get the same power and efficiency out of the Curtis as I would out of the Alltrax? THANK YOU FOR YOUR RESPONSE AND HELP!!!!!
