Universal throttle for electric bicycles scooters, quads and simmilar devices , has key switch, voltmeter and hall-based throttle in this article can you read my review and how to correctly connect the wires to the control unit
Here are the pros and cons of Ebike throttle with switch and voltmeter 12V-72V:
Here is pros:
Good price 8-15usd
Have voltmeter with measurement battery voltage 12-72V compatible with most ebikes
Can buy version with button switch or key switch
Nice design when the handle is new
Here is cons:
Shiny metallic parts,can scratch
Wiring may bee problematic (how to connect the wires below in the article)
My verdict: It’s a useful throttle for e-bike, quad bike, electric scooters shows an accurate voltage of, for example, 37.5V this shows an accurate voltage of, for example, 37.5V this is much better than three LEDs (green yelow red).Keys have a protective effect against stealing.he design is nice but the colorful “metal”. Battery compatibility is high can you use for lead acid ,li-ion,li-po,lifepo4,nimh,nicd akkus , here is here are confirmed nominal voltages:
12V
24V
36V
48V
60V
72V
Wiring manual guide – how connect this throttle:
Description of the electrical wires for proper connection of the handle to the control unit:
In wire black connector:
Green – signal
Red + 5v
Black -5V
*Most often, in the control units, the signal wire at the center is between + 5V and -5V. The wires in the connector must be moved to match the connector on the control unit.
Yelow and Blue wires is for switch and voltage measurement:
Be careful to handle the nominal voltage apparently directly from the battery, short circuit or wrong connection may damage the control unit or other components of the electric bike
Here is switch schematic
Read this before connect this wirres is important
Connect Blue wire to controller power ON wire with nominal voltage (12,24,36,48,60,72V)
in most controllers is thin red wire in battery connector or ignition cable . if it comes to the yellow wire voltage of 36V voltmeter will light up. (If you not have ignition wire from controller dont connect blue wire ,insulate it)
Yellow wire connect to battery main plus pole connector (eg. +36V )
3 wires, black, green, red already connected to the control unit, special black wire is for voltmeter on throttle negative GND.
dont connect red and black wire by throttle switch (you make big short circuit)
Here is video how this throttle work with Controller:
Compatibility with e-bike scooter control units
Owners of the yiyun control unit will be pleased, this throthle is fully compatible with this controller.
Wiring in hall speed conector is fully compatible (green to green,red to red,black to black) you have to change only the throttle connector – have small black and controller have biger white connector.
Ignition switch ON have YK31C “blue” and “red”, blue wire from throtle connect to blue wire on controller, yelow connect to red wire ,and we have it.. (btw.. YK31C have on red wire battery nominal voltage eg. +36V , blue wire -36V)
If you need help or you want to ask me to write comment thanks..
Most problem is on diferend coloring wires on throtle and from Imortor central unit… muss measure with multimeter you need +5V -5V and signal … wire from voltmeter can plug in +36V on bathery .. key switch is question….
So the little blue wire is to the little blue on the throttle that’s the key. And the little red to the little yellow wire on the throttle is +36v is that correct. Thanks Warren.
blue wire and yelow wire is switch , on this wires can conent to battery voltage,but ot red wire or other from throtle, your controller has been damaged
Thank you, just the info I needed. I couldn’t figure out what to do with the blue wire, meanwhile the throttle would operate whether the key ws on or off. A million praises to you!!!
hello guys can anyone help me to wire the yiyun throttle to a controller which doesn’t have ignition wire only the 3 throttle wires…with the throttle wires i don’t have a problem as my main issue is where do i wire the blue and yellow wires as my controller has only the electric door wire which goes to + terminal of battery
Ivan, I am desperate need of help. All throttles with some on/off switch has same extra blue and yellow wire. I dont know how to wires these two wires to VESC, having large XT90 connectors to the Lipo battery. Do you know how to integrate using this speed controller instead?
This wires is combination switch and voltmeter if you controller activating add one extra wire for + battery power voltage , i see controller schematic i have not idea how work but carefuly , throtle use on switch or voltmeter
Hi Ivan – I have a CON611 controller (see image attached with wiring spec). This does not seem to have an ignition wire for me to connect the blue wite to. Can you suggest how I can connect this please?
Hi, I want to usw this on my Xiaomi M365. I understand the connection for the throttle because I can just comnect it directly to the old throttle connector, but the yellow and blue, I still dont know where to connect them for the volt meter. I am planning to just separate the red and black for the throttle and the voltmeter so I wont be confused but I still need help on the blue and yellow. Please help…
Maybee is beter not plug , bee carefull voltage is 36V dont connet to 5V throtle, you muss lokalize switch wire on board (with multimeter beeper, switch on – multimeter beeping). This throtle is good for chinese controller sell on aliexpress or ebay with two red wire in power plug.
12V

Very helpful thank you!
Please help me connect my universal throttle (blue digital, item#14297811976) to my Imortor 1.0 36v 240w. 5 wire Colors match, but don’t work. ? 🤔

I have the same problem, still not clear to me.
My throttle have 7 wires how can i connect it plsss help me…

So far All i know is that the Green Red and Black go to the ADC connector port, thats all. Really need help with Blue and Yellow for VESC application.

Hi – can you advise on how to connect the Blue (switch) wire to the Con611 controller shown in the attached diagram please?

Controller not support switch , can you connect blue or yelow wire to + pole battery for activate voltmeter

I don’t hace switch for ignition, can I make one myself? Is it just a switch or it needs more components
