Help needed with new Scooter

RS485 is a coms protocol..

RS485 is a coms protocol..

So i could connect a module there to diagnose it and maybe reprogram it? Any ideas?

For starters, i bought This to see if i can do something, but i am not optimistic. I just want to make tests to the controller.

Now, i want to buy the below from an EU warehouse, so they can arrive faster and not to have to pay taxes from China.

Controller
Screen
Switches

I want to ask something important now. I see that the new controller says hall angle 60 degrees, my old controller says phase angle 120 degrees. Will it work?

Update as of today. I cancelled the order from AliExpress, because i am not sure if they will indeed fit and if Votol EM-150sp has self-learning function. No one can reply this to me and i have not found something on the Internet. I don't want to have problems with hall/phase angles.

I am waiting for the USB to RS485 adaptor and if i am lucky maybe i can get some readings about my controller/motor and then i can get to the next step.

For the time being, i made a better soldering job on my current controller and upgraded all 4 capacitors from 100v-330μf to 100v-440μf. Plus i changed the 63A relay that my scooter had to an 80A automatic fuse. Total speed has not increased but for sure we have better torque now. It is very noticeable.

Next upgrade will be to change the positive and negative wires with good quality ones to try and minimise the voltage drop / stabilize it when going full throttle.

These are just small upgrades that cost almost nothing and can make it a lot safer/better.

Hello Everyone,

I bought about 2 weeks ago an electric scooter with the attached specs (you can see the motor hub/controller).
The motor rating is 2600watts.

I bypassed the speed limit and I can hit up to 55km/h (it's easy, it's just a cable in the controller), but i would like to make it a bit faster.

Thing is that i cannot find anything about my controller on the internet and if there is any chance to connect it to a PC and check the details or re-program it. I would like it to be able to go around 70km/h.

Any ideas?

I have also thought about buying a new controller - better one to match it with my current set-up but i need your help in this. Any suggestions? And also do I have to change the screen/speedometer?

A far driver sinewave controller you can't go wrong with those

Will give a look at them as well, apart from Votol. Thanks for this

I tried to search on this forum but i could not find anything. Any idea if you can put somehow a temperature sensor or generally, how to check temperatures of controller?

Handheld of infrared thermometer like the ones that mechanics use and they pointed at different parts of an engine that should work

True, i have this infrared thermometer, but i do not have access to the controller all the time, especially while i am riding.
I want to see what temps i get during full speed like "real - time" information

Use RTV Silicone to attach the bead to whatever you want to measure.

Thanks! Already ordered it. Will revert once i make more upgrades.

Today i received this adaptor. Will connect it to 485A & 485B to my controllers motherboard - ground and 5v if required, i can connect them as well.
Thing is, with what program i could connect to the controller and read / write data? Any ideas?
