Re: How to get rid of throttle speed limit?

Thank you for your answer. Well, I kind of used a GPS app. I'm going 50 actually. And can go over 50. But somehow, the wheel size presets arent working. I can set in inch, or centimeters. Well, my wheel is about 75cm across with tires on. 26" rim. and when I sit on it, its about 72. It shows WAAAY t...

How to get rid of throttle speed limit?

Hey guys! I have an 5000W RisunMotor kit, the controller is an "36 MOSFET 100A" It has a 750c display. QS205 hub. There is an option to set the wheel size. Do I set rim, or do I set tire included? I measured, it's 74cm so like a 29" with the tire. Without the tire, it's a 26" rim. This is my first p...

Re: QS-205 5000W kit Error 30H

Hey! The display was replaced. No more flashing. It's still showing up as Error 30H. The controller had the cables kind of pulled out from the side the display cable is in. I shipped the controller back for the second time now. Should be back in a couple of weeks. Anything else I should check after?

Re: QS-205 5000W kit Error 30H

This is the EXACT same display that I have. The 750C. But mine is for 72 volts too, you can set it in display settings, and yeah. I put 160 volts trough it.... So it carries the full voltage? Oh god. Surprised it still turns on, and works. To be fair, the odometer part flashes sometimes (like the se...

Re: QS-205 5000W kit Error 30H

If you have a comm error with the display, you’d better try running the motor with the display unplugged. Too bad you don’t have any other comm options (bluetooth or RS232), because the controller may need to be set in the program. There has to be a switching circuit, a wire that powers the control...

Re: QS-205 5000W kit Error 30H

Hello. I don't have a bluetooth dongle thing. The seller says the kit needs the display. And I have no idea why it doesn't work. It does not turn tho. Again it's supposed to be a communication error between the display and the controller.. and it can mean the controller won't run the engine. Stupid,...

Hello! I'm back here, because I really need to fix this, the whole setup was about 2000$. I checked the connection from the controller to the display. The order of wires are: Yellow, Green, Black, Orange, Red. But on the display the wires are Yellow, Green, Black, Blue, Red. So on the display instea...

Re: QS-205 5000W kit Error 30H

Let me add: I have wired 2 batteries in SERIES before by mistake, so I gave it 160-164 volts. They replaced the controller. Any other parts could be damaged?

Re: RisunMotor 5000W kit Error 30H

Okay. I read up on this a lot more. I see battery voltage, so the controller is probably getting electricity. What else can I check?

QS-205 5000W kit Error 30H

Hello. I have a RisunMotor 5000W kit, and the display shows Error 30H. I checked the connections, they should be OK. It's also showing a little blue engine icon over it, and the wheel is not spinning. I don't know what could be wrong with it.

Hey. I live in Europe, so no harbor freight, nor anything free. I don't know about the keyswitch thing. I don't have one of them. I have to turn it on with a thing connected to the display.

Re: Blown new MOSFET controller!

I hope so.

I have an old 100W solder thing. I'll try to replace it if the seller can't/wont. Probably will, theres a 1 year warranty.

Re: Blown new MOSFET controller!

I have an old volt meter that has like a thing that can measure AC DC volt up to 500v, and battery. No soldering skill, but can weld. No ohm meter.

This is a 5000W controller so doubt it.
