Re: Sabvoton 72xxx 21S regen

You are right. I just conducted the experiment. I made a sloppy 90volt pack from scrapped cells to test it. It only regens up to 84 volt and above it it releases the motor. I dont really know what to do tho. I ordered 714 cells for a 21S34P config. I hope I can cancel 34cells. Tooo baad that extra ...

Re: Please help: Sabvoton 72150 controller setup issue

My understanding is that QS make their own motors and the Sabvoton version controller. They also stock and sell other makes. I have been using them direct for about 5 years and to date have never had any problems with their stuff. I deal direct with them, not via any outlets and have found that most...

Re: Please help: Sabvoton 72150 controller setup issue

I tested with 120A mid throttle current(standard setting), low speed at 70% (max percentage it would allow), mid speed at 100%, "high speed" wire connected to ground, internal speed limit at 100%, both in "boost" mode and in "3 speed switch" mode. Still the same top sp...

Re: Please help: Sabvoton 72150 controller setup issue

@Santacruz unrelated : Are you using e-brake on your controller? If so are you using an e-brake throttle or a switch? How did you manage to get it working? Thank you! Yes, I am using a left half twist throttle. Just plugged in. However, it needs to be set with a pc program. I say that, as each time...

Re: Please help: Sabvoton 72150 controller setup issue

I am running a 96120, but my wiring is similar. Looking at your program parameters (again similar to mine - except amps) I see that your (under motor tab) motor speed limit is set to 65%. What I have done with mine is (using no limit) set motor speed limit and mid speed limit to 100%. I would have s...

I only see a link to this thread for the UUG on the CA info pages at Grin's site.
My appolgies.
It was only a few weeks ago that I downloaded the UUG. I see now that it is not available.
So, disregard my post, it is obviously wrong.
But, Grin should remove it from their site, I think.

No sine wave with field weakening selected?

I was reading an article about a controller and it was stated that with field weakening the controller becomes square wave. This is news to me and raises some questions. I have a Sabvoton 96120 running a QS273 motor and have field weakening set to 50amps. Is it correct that the controller is running...

Re: Off Road Throttle which one do you prefer?

I have tried a few and my favourite is the grin slim right hand half twist. so slim can fit shifter without interference. I like how the twist and grip are same diameter. The Chinese ones all seem to have a fatter twist part, which i can't stand. Most throttles are cheap enough you can get a few an...

I’d trim your seat post. I know it won’t hit as is just looks funny. It’s non stealth with the logos and graphics and color scheme. I know this is a personal preference, just not for me. Otherwise great ride!
Saddle post is a Hyd dropper, so it is not possible to cut it down.

What turn is the 3k motor? and depending on how you have it programmed the controller will be in mid or low settings. If you do not have a 3-speed switch? I would go into the app or PC program and set all 3 powers settings to max or whatever you like so you know what it is doing... Also, you can pr...

Santacruz,
did you open damaged charger?
which components burned, capacitors, MOSFETs?...
I only opened it to see and take a photo of the damage, to send to the seller.
It looks like the main relay at the output circuit, but I have not gone that far into it.

Question over different pole pairs in motors

Hi all, I have searched, but not really found a simplified answer. That is pole pairs in a motor. I take as an example, MXUS 3k - 23 pole pairs and a QS205 3k - 16 pole pairs. So one has 46 magnets and one has 32 magnets. Does this have something to do with RPM or torque or even reliability? What is...
