Brushless Controller, 36V/48V 350W 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!

Awesome

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.

I liked the fact that all the connector ends were labeled in Chinese and English. I hooked it to a hub motor using just 3 wires and it worked, no sensor wires required.

What a PITA to decipher. But I've got it figured out so you don't have to. Works well for my 52v scooter. (52v is considered a safe overvolt for 48v designs, so feel free to run 52v through the 350w controller. It's a nice little boost).There is no on/off switch! Once the controller is plugged in to a battery, IT'S ON.DO NOT wire the accessory "anti theft" to an on/off switch, you will short out the controller. Bonus points to the controller for this on, because it didn't damage it when I accidentally did that. The circuit is like a cigarette lighter in the car, it supplies full battery voltage. It was designed to power an Anti-Theft controller for a full sized moped style scooter. This is also the purpose of the 3-wire "Anti-Theft type line" , so you can safely ignore them without a problem.The only things you HAVE to wire up to make this controller work are:1: Battery Input (Large 3 wire 2 Pin plug)2: Brushless Motor Leads (Yellow, Blue, Green)3: Throttle (3- Wire plug)4: Hall Effect (5-Wire Plug)3 Speed Circuit Plug:Blue + Black = HIGH.Untouched = MEDBrown + Black = LOWI'm assuming low level brake cuts power when the brakes are applied. It's unclear if adding high level brake to that circuit adds Regen or if it is supposed to supply power to brake lights, but I'll try to find out soon.

Broken after 32 days, I don't I don't know is it has a warranty or not but after two days after amazon return period was ended it was broked

Used on a swagtron eb5 upgrade to 48v. Does about 22mph. Only thing that would have made it perfect would have been pedal assist capability.

there's not feasible way to power it the port is wired incorrectly
