Switching a ebike controller to a e scooter controller

[soprano_415]

My main objective here is to connect my leads. I saw a previous post similar to mine and a response was to write down the numbers/letters on the controller so I've gone ahead and done that and I've attached it to the post. (i attached a picture of the side I wrote down)

Controller A



Okay so below is a picture of the the leads I'm trying to connect to thru the controller In the first half of my post. The controllers have different colors wires so I need to know where the wires from controller "B" connect to on controller "A"

Controller B


I want to say in advance that I appreciate any help that any of you could provide to me so thank you!

Your Controller A seems to be a sensorless square wave controller from Lishui. The motor halls are connected to pads SA, SB, SC normally. These pads are missing on the PCB

Your controller B has connectors for the motor halls. So perhaps it can't work sensorless. If your motor has no hall sensors, controller B may not be compatible with you motor.

Scooters are normally driven by UART commands coming from the dashboard. E-Bike controllers are driven by throttle or PAS/torquesensor, that are attached to the controller directly....

So is it not possible to connect the leads from con. B to con. A then?

Thank you for your response, your help is very much appreciated!

Also I forgot to mention this before the reason I want to connect them is because con. B has a blown fuse somewhere i believe, and con. A is my only other controller i have available to use. And I need con. A to be able to connect to con. Bs battery

A is my only other controller i have available to use.

Sorry I still can't get you problem. Your vehicle is a scooter ?
You want to drive the scooter with the E-Bike controller?

Yes is that not possible ?

Of course it is possible.
You need at least the battery, the three phase wires and the throttle connected.
The throttle signal has to be connected to pin "SP". +5V and Gnd to the red and the black wire of the throttle connector.
To switch on the controller, "SW" (blue wire normally) has to be connected to VB+
With this minimum wiring, the motor should start by operating the throttle.
Perhaps the hallsensor signals from the motor have to be connected to HA, HB, HC. With +5V and GND on the red and the black wire of the hallsensor connector.
But if they are needed, it might be a little tricky to find the right hallsensor/phase combination.

Thank you very much for that it's really what I needed to get it going

Thank you so much you've been super helpful I appreciate it!

One last thing do you know what this is for and if so will I need to use it to do what I'm tryna do and if yes how do I use it ? Thank you again
