I finally got the bluetooth module. I can connect with my phone using a Wechat mini-app in Chinese only. Fiddled with pretty much all the settings and the best I can get is 180A at 0RPM, exactly the same as with the EM150. Matched with a 8KW QS273 and a 72V battery capable of 600A discharge...

As I said in the original post, there isn't a single doubt a QS273 outruns a QS205 all day everyday. Only when matched with a controller such as the EM150 can the 205 outrun a 273. The controller output isn't the same for both motors, that's why. If it was the same, with similar KV, the...

I don't have tools to measure inductance. Phase resistance is around 7 milliohm for the 273, more than twice that for the 205. I can try and measure again but neither resistance or inductance is dependent on RPM as far as I know of. Even if they are, I can only get a reading when the motor is...

Yeah. I measured it a while back, the phase resistance is substancially higher on the 205 than it is on the 273. I have a milliohmmeter. I forgot the exact numbers. KV's are the same or almost the same, 14 rpm per volt. I don't see how that would make a difference at 0RPM. The controller...

Yes, the 205 actually has a lot more kick from the get go. Pops big wheelies. No wheely with the 273, far from it. At higher speed I can't tell the difference. Peak battery amps are measured using an analog Ammeter and readings are consistent with the BMS readings. I'm sure the measurements...

Can you guys connect to the computer? I had no luck so far. I'm using the data cable provided with the controller, software version EM_V3-49 and windows 10. Set baud rate to 115200. Got the right COM port, appears to connect but I get the error message from the controller app ''communication...

I read that in a group a few years ago and thought that was quite a laughable statement. I have both motors. I cooked a 205 at 30KW while the 273 happily handles 42KW and hardly gets warm. The maximum torque of the 273 surpasses that of the 205 by far, there’s no question about it. However I...

南京 Nanjing (Capital City of the South) 远 far 去go. I've seen it translated as ''Nanjing Far Drive''. They use the Bombardier logo. Be assured, the staff working on the controller design got their sh!t together better than those in the marketing department.

No. It's 南京远去. I have a APT 72800 awaiting test, its a third of the power and trice the size.

No replacement, they're out of production. The first one never worked, the second one worked great for 24 hours then failed at startup, one day after losing connectivity with the computer. Bought it from the QS taobao shop in China, got my money back. Forget Votol, at least for now. I...

Votol EM200 and EM300 are either defective right out the box or fail after a few days. The EM300 is the most powerful controller I tried so far (more power than MOBIPUS). It worked for 48 hours.

It doesnt seem like it a has variable regen function, does it?

I'm contemplating getting one of these EM300 units. I heard they came in first in some ebike races in China and that they can do 0-100 in 3 seconds with a 12'' hub motor. I'd love to hear more feedback about programming, I'm a little concerned about the apparent lack of support from the...

A Chuck Norris kind of fact, yeah

Its an open source design-75% size copy of a 1980's yamaha. Different factories will offer different quality ranging from absolute garbage to acceptable. +The bike is easy to work on and once converted weights only 100kg -Rims are steel -The original front brake didnt brake at all +The...
