Adding a 3-speed swich

[Carl.H]

Hello

iám a noob in this area so this might be undoable

i want to add a 3-speed swich to my board

here is what it looks like, is this possible?

If you have or add a cycle analyst v3 as a display you plug the 3 way switch into it.

Where did you buy your controller?? I am looking for sources of that one, that uses STM32F030 microcontroller.

The controller is from a citycoco (scrooser)
12 mosfets and sinewave drive
only 1000w

U can almost get them for free

Thank you!!

Can tell you that a chinese developer is looking at that controller to make OpenSource firmware for it... I am gathering information and see if there is advantage to adopt that controllers and join the project. citycoco (scrooser) seems that will be famous/success product so maybe I will join...

So there is perhaps some way to make it run slower? I want it to do max 20km/h

As an hacking/mod I don't think so as original firmware should measure motor speed but looking hall sensors signal and that signal can't be cheated as it is also crucial for motor running.

If we do the OpenSource firmware, then we will for sure implement speed and current control, since the most advanced throttle control is a mix of current + speed control.
With our firmware we will go to the max possible by the hardware, things like unlimited speed and current will be possible - the limitations will be only the physical hardware and not the firmware.

Ok so there is a way to kontroll rpm of the engine then mabye?

I don't think is possible to control motor rpm.

The only think possible is simulate 3 diffetent throttle posititons.

Is it possible to add a bluetooth module to this controller?
I have one from an YuYang king controller, I think it has 4 connectors.
And use your app to monitor current and speed,
That would be great

I don't have any of that controllers so I don't know.

Hello

yes i see, then i will change this one for the 50 amp yuyang king controller,
its a bit sad to do it because i will miss the silence, all u hear is a high pich on going beep

The yuyang king is supposed to be more powerful, maby it is but not that much, it has how ever ways to controll the top speed.
but it sounds terrible in lower speeds

If you prefer a physical LCD, then I suggest for you to go with Kunteng / BMSBattery controllers.

Ok are those sine wave controllers?

I found similar controllers to the one I posted in the first post.
And they have the 3-speed connectors.
So I guess there have to be some soldering points were they are connected.
Google ain't that helpful or I am searching in the wrong direction

Yes sinewave and with a lot of options on the LCD or mobile app via bluetooth. Read the manual of the LCD to understand.
