12v Bike motor test successful!

I tested it at 12v on the bike and everything worked perfectly!


I'll mess around a bit more at higher voltages, and check out the spikes, and then I'll put it in the car by this weekend, and take it for a drive.

A 144v 500amp bike controller! hahaha! It's nice, the pack voltage input range is 0v to 144v DC. So, let's say you have that controller, and all you have in your car are some 1.5v AA batteries. It would be perfectly fine to run the car on them. No problem! The top speed might not let you keep up with traffic though.

I have a slight concern about one of the mosfets. I checked the resistance across it from drain to source, and it read 500kOhms. It could have been because I was touching it or something and it was reading my resistance? All the others read OPEN CIRCUIT because the resistance was too high. It might be nothing, but I'm going to keep an eye on things. Worst case senario, I'll remove it, and leave it at 500 amp current limit, because I think the mosfets can take it.
