That breaker looks like it should be OK. It also can double as a main power switch. If the controller takes more than the breaker rating, the breaker might trip when you don't want it to. You really only want it to trip when something shorts out. They can usually take a little over their rating for short bursts without tripping.
So... what is this controller going on?
Thanks that's good to hear i will pick one up soon!
So I wanted a bike to get across fields/campsites (battling my mates other toys) etc and had to be very small to go in the camper van and had this old mini dirt bike chassis buried at the bottom of the shed and two of these old but hardly used brushed motors, I think they might be out of golf caddies and I presume the small ride on ones as I couldn't imagine motors of this size needed just to lug around some clubs but I could be wrong!
Any way the motors had a massive reduction drive on them something like 50-1 but I never though they were use able as the motors say 156 rpm at 24v which I always thought was ridiculously low rpm but I think now that it was just the rpm after being reduced.
So I picked up a cheap yiyun to see if one motor would pull me around and sure enough it does! however I have no idea of the rpm direct from the motor. I have tried running at 48v which is getting the motor pretty hot (the controller is coool) and cannot reduce my gearing any more unless i have a custom sprocket made with or another reduction drive which I cant really be bothered with although is probably the best option.
Only other thing I can think is reduce the voltage so it doesn't get hot but sacrifice top speed (which im really not concerned about as it goes way tooo quick! probably around 30-35mph and on this tiny thing is pretty hairy! Only thing is reducing the voltage doesn't help with the acceleration and climbing ability like a lower gear would.
sooo.... Im now wondering should I just run both motors in parallel?
I may as well make use of them haha then it would have some great low end pull on 6s or crazy scary fun on 12s??
Any suggestions let me know!
