If you are going to mod it I would mod it properly. I have the bike driving btw, however haven't driven it much. The performance is amazing, so much quicker than stock, it's a blast everytime I get on the bike.

I get the error "Abnormal start" on the Discharge MOS when I turn on the BMS. Since it cuts of the discharge nothings working. Searched the thread but didn't find anything. Also tried closing and re-opening the discharge and obv did a factory reset but the problem persists.

NVM, problem solved.

I'be been driving my setup a bit but the motor sometimes vibrates a bit... It feels like it's holding back and then suddenly gets it's power and hauls ass. I can't get it on video, it's more something that you feel than hear. Do others have similar experiences or what could be causing this?

I've bypassed the BMS and the controller is perfectly fine, the problem really is within the BMS. For now I've taken out the BMS and did some small runs without the BMS. Will order a new one now. Still think it's only a software issue and the hardware of the BMS is fine but I can't get it to...

Just tried the trick I've posted in the above video. I've noticed that it doesn't matter whether I select "sw" or not it does regen the same. It has to the with the value on page 1 "rate of decline". I'm noticing it has regen the higher the value the higher the regen. This however stops at a...

Sorry for the late reply, had some crazy days at work. I haven't bypassed the BMS yet. I meant it doesn't matter whether the BMS is on or off, the bike doesn't work. I still get the error even when nothing is connected. I've made a video and some pictures if anyone care to take a look, I...

Hmm..I posted this question on another forum as well with all the extra info, though I did it here as well, apparently I didn't, my apologies. Yes I still get the error even when nothing else is connected. I can still connect the controller to the pc and read the rpm when I turn the wheel...

The bike doesn't work at all, regardless of the BMS. What happened is that I switched the positive and negative on the controller. I can't do much more than look? I read that you measured each individual mosfet, but I'm totally clueless about how to go about such a thing.

I assume with output you mean voltage? Voltage on the + battery and - battery is 80.1V (20S @ 4.0V) Voltage on the + battery and C- BMS is 77.2V Voltage on the + battery and C- BMS is 80.1V with BMS on Voltage on the + battery and C- BMS is 77.9V with BMS in error mode I didn't find your post...

Goodluck with correcting all the wrong info on the internet, don't wear yourself out. As I said, I mistyped (was on my way and typing on my cellphone), i'm terribly sorry for that. I hope I didn't ruine anyone's live.

Anyone? Finally the seller got back to me (holiday in China apparently). They asked me to restart (already tried that ofc), and then they said ship it back... That's like having no support. Is there anyone that might have an idea of what's wrong? Dont want to loose the BMS for over a month or so...

They are only (bad) typos, I've corrected them. If one doesn't know the difference between A and Ah one shouldn't be building battery packs. Regarding the controller ratings. I've read many different stories, these numbers however, are the only ones that make the numbers work provided by Super...

The stock motor and the QS273 are not the same. The QS one weighs way way more and the settings for the QS didn't work in the stock motor.

It's the QS273 motor, not QS276. I also believe the motors will be identical, would make sense since producing 1 motor is easier and probably cheaper than producing 2 (this is often done in the automotive industry as well). TS Controller: 40A (60V *40A = 2.400W peak = 1.200w continuous)...
