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.

    Actually helps dry mouth!
    I’m giving this product 4.5/5. It works really well for dry mouth during sleep. I recommend starting with 1 tablet and adding a second one only if necessary. (I require 2 tablets at night). This is called “slightly sweet” and is relatively tasteless with a hint of sweetness. During daytime usage, I’ve been using 2 tablets at a time. The only issue I have during the day is that if I can’t drink on a regular basis I get the white coating from the tablets in the corners of my mouth. I do think that this is the next best product to use when taking sips of water isn’t possible. Works as stated and easily adheres to your gum line/partial tooth. I place them in the back of my mouth and they are not noticeable to others. Added bonus, they don’t leave a slimy coating on your teeth the way a mouth rinse does. Product performs better than expected! If you have dry mouth for any reason please consider giving these a try!!! I wish I would have known about them years ago!!!

    Works for dry mouth
    Suffer from dry mouth and these disc size tablets stick to my gums, helping keep my mouth moist through the night. Brown side sticks to your gum. Contain xylitol so s little sweet. Dentist recommended them.

    PRICEY and sometimes don’t stay in place!
    These have a wonderful mild flavor, no mint burn, moisten your mouth for several hours, and generally always stay put, in fact if you want it out before fully dissolved, it takes a little effort with your fingernail, because they are supposed to stick and stay in place! ALSO, I DO NOT PUT ON MY GUMLINE LIKE THE INSTRUCTIONS SAY, I STICK ON THE ROOF OF MY MOUTH FOR DISCREET CONFORT!! I really do recommend for DRY MOUTH!! I DO NOT CARE FOR THE SHARP EDGY METAL INDIVIDUAL PACKAGING AT ALL, but the bottle is very pricey!!

    Absolutely work!
    These are absolutely fantastic. Bygone are the days of sucking on some sugary sweet Candy. Xylo melts stick as they say they do. I have found that they don't stick to artificial teeth as well. They last for hours they're comfortable. The mint ones aren't overpowering. These are a dry mouth blessing. For sure use them at night and during the day.
