Intelligent Brushless Sine Controller 36V 48V 60V 72V 84V 2000W Maximum Current 50A Aluminium Alloy E-Bike Brushless Motor Controller for Electric Bicycle Scooter

I got this to spice up my Caroma D3 electric scooter that I purchased here on Amazon and it has done exactly that. Currently running the stock motor and battery and just adding this controller has improved the acceleration and top speed considerably. Right now the stock battery is holding back what this controller can do since the bms cuts out simply not being able to provide enough amps so for now i can only use the medium speed since the high speed option requires more power than what the stock battery can provide so now im on the hunt for an affordable battery with more volts and amps that can really let this controller shine. Ill ad a short video showing the different speeds and potential of this controller with no load applied so it doesn't trip the bms. Overall very satisfied and consider this controller to be a great value.

I am updating my review. I could not get it to go at first I rewired a new throttle to match the controller. This thing is absolutely amazing for the price. I have it stalled in a razor MX 650 go 30 miles an hour in the second speed setting my battery isn’t strong enough for number three overall I will be ordering more of these in the future

I haven't had any issues with this controller and like other owners. It is more powerful than your same controllers at this price point.

This has no wires to connect the motor to, has wires for everything else. Will not work

Worked very well for the first 15 minutes. Good torque, awesome acceleration while ran on 60v. I’d say I was getting around 30-35 mph with my brushless hub motor. But then it cut out going up a slight hill. Continued to cut out more and more as the ride went on, even on flat even surfaces. Eventually walked the scooter back home when I lost all throttle function. Seems fried, has power running through it but won’t move the motor. Tried another controller and works fine. Seems like junk. Update new controller was sent in replacement seems to run good. Only complaint is a hooked up a three way switch to the 3 speed plug and it seems to have only 2 speeds. I’m hoping the fastest of the two is top speed. It’s fairly decent. Update: second replacement controller did the same as the first, started cutting out when under full power. Didn’t blow a fuse. Then quit for good only showing lowest power on my meter. Don’t buy

So I see this controller is labeled as “frequently retuned” and I can only assume it’s primarily errors on the part of the user.. I’ve purchased, installed and used many many brushless controllers over the years and am not sure what the issue people are having is bc while this is clearly no FarDriver it punches well above its weight class and for $50! I can’t say enough about it.. it’s almost as powerful as a Kunray 3000w and honestly performs up with $150-$200 FarDriver and Votol controllers although it has very few features as compared to those higher end companies. it does however pack a substantial punch for a 50A controller with all the more Standard features. Would have loved to see regen but hey it’s $50.. and I have yet to see any sub $100 controller support such a wide voltage range from 36v all the way up to 84v.. it’s relatively small for its output making it a great choice if space is limited.. I personally use a FarDriver 72680 on my bike and a Sabvoton 72300 on another and with all my higher expectations this controller really blew me away on a budget scooter controller swap I did.. I love this little guy and am considering just buying a couple more just to have bc I’m sure the price won’t stay at $50. I will admit the instructions have a lot to be desired so I wouldn’t recommend any of the Chinese controller if you have no experience installing them bc the wiring from company to company varies and there isn’t a lot of continuity in that respect so fir example green wire for this companies controller may not be the same for another.. and always remember when in doubt, don’t..

Works amazing and very easy to set up and use

There are no motor or controller wires included. You must open the metal case, find the terminals, and attach them yourself. Really?
