High-Discharge High-Speed Controller

YYK controllers are the reliable workhorse square wave high speed controllers used in our upgraded Fiido e-scooters. They are relatively cheap and easy to use without much configuration needed.

Square Wave Controller Description

The YYK controller is a square wave high discharge high speed controller. Discharge current rates start from 50A all the way to 150A. And they can accommodate a variety of voltages from 48V to 72V or 100-120V. The YYK is a universal controller which is easy to wire up and to adapt to virtually any e-bike or e-scooter drive train.

Here is how the YYK square wave controller works:

 

Controller Configuration via Bluetooth App

Here is how to download your YYK app to configure the wide range of parameters to adjust the power, acceleration and speed of your new YYK powered Fiido e-scooter! 

Sinewave FOC Controller

Our sinewave FOC controllers are smoother and more efficient without sacrificing the torque and top speed of squarewave controllers. From launch, the sinewave foc controllers will feel more gradual and smooth whereas squarewave versions will feel more torquey and jerky.

We have available the 50A and 70A versions of the sinewave controller. 

Specifications

    Nice weight, feels very high quality
    Color: Matte Black
    I did not expect the stand and handle to have such a nice weight to them, the stand does not tip or move it all when I am getting the distributor in and out. The tool itself also works great, and it even comes with extra needles if you need to replace them. Truly feels like a much higher quality item than the price would have you think.

    Epic. Works great.
    Color: Black
    Works great every day. Super powerful and smooth compared to my old battery powered one. The shaft is much thicker and is more securely positioned so I can't imagine it becoming tweaked off balance like my old one. And it comes with an extra mixer attachment! I imagine I've put that away for a long time, but we'll see. Easy to turn on and off with one hand, but I can imagine it being less easy than a simple push button for someone with decreased thumb dexterity or mobility. I do wish the lowest speed was slightly lower, but it hasn't caused any splashing or other detriment. The speed adjustment is very smooth and power is abundant. Love the stand, Usb c charge port is solid, battery life is excellent.

    You want this one, for power and quality and saving on AA battery costs
    Color: Black
    Yes. You want this one, for power and quality and saving on AA battery costs — buy it now. Don’t waste any more time comparing products. After hours, days, weeks, of researching and comparing, I ordered this one. I do not regret it. It is powerful. It was less than $25 when I bought it. It has a USB charger port and it feels solid in your hand. It has a turn-knob at the top to control the variable speed immersion blender aka milk frother aka wand frother. Charge battery fully for 2hrs before first use and then you’re all set. It works very well. It functioned as expected and then even better. Yes. It exceeded expectations. I hope it lasts a long time. It feels like it is very well made and high quality. Classiest and best wand frother I have ever owned. And I’ve owned over 3-4 in the past 10yrs. I got this one at $25 instead of the highest-rated one for $9.99 because those require AA batteries and this frother however is USB-C rechargeable! So in 1-2 years it will have paid for itself in battery costs alone. But there’s no price I can put on how enjoyable it is to use this super powerful, super smooth, high quality, wand frother.

    Quality Design
    Color: Gray
    Excellent frother/mixer Pros: - Quality feels premium. - Plenty of power to mix even with a drink packed with ice and peanut butter. Basically a mini handheld mixer. - Ease of use is great. I appreciated that this had a longer brother so I can mix drinks in taller cups. Also the grip is fantastic and it is easy very easy to change the speed with just one hand so you can hold the drink with the other. Longevity - So far it's been holding up and hasn't needed a battery replacement. Cons: None so far.

    Highly recommend!
    Color: Gray
    Love this frother!!! Purchased to replace an Aerolatte that stopped working after a reasonable period of use. Right out of the box, it was charged and ready to go. I’ve been using it daily for about 5 weeks on the same charge it had on arrival and it’s still going strong. Love the variable speed and easy to work with one hand. And this baby can froth! It froths far better than our old Aerolatte. Also love the rechargeable feature so no more AA batteries wasted. This handy kitchen tool makes my morning coffee a true highlight. Highly recommend the Maestri milk frother!
