Opaltool Brushless Controller, 36V/48V Aluminium Alloy E-Bike Brushless Motor Controller for Electric Bicycle Scooter

This motor controller is being used as a replacement for a failed motor controller in .y Lectric XP Lite.Unlike the motor controller in the XP Lite, this controller doesn't feel like it constrains your speed to a preset limit as is the case with the original equipment, although I have not been able to accurately clock my speed since replacing the original controller. I will update my review when I'm able to report actual data.This controller feels to me like it has more torque than the original controller, although I suspect that it also puts more drain on the battery as i recently had my first dead battery experience (I have put about 1200 miles on the bike) when I stretched out my usual commute to about 13 miles. The original controller has a 15amp power restriction feature that squeezes a lot more milage out of the batteryI have to date connected only the throttle and voltage meter, and i will update as the other features of this controller are accessed. I suspect that using the "low speed" option doesn't slow the bike down at cruising speeds and probably squeezes more milage out of the battery; more to come on that when I access the feature.To date I have ridden to work (10 miles each way, with a recharge at work) about six times and the controller has proven reliable, with no malfunctioning problems to date. The bike feels peppy and I'm happy with the product!

Use the two white wires, should read learning not leaming.When you connect the white learning wires together the motor direction can be reversed@DALJEET. P.

Works great let my jetson run up to 18 mph

works but had to run power wires backward to make work

This controller works fine. Just be prepared to search for wiring instruction as they don't come with item. Other then that is performs as expect once you research wiring.
