    Votol EM-260

    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...

    My QS205 runs circles around a QS273!

    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...

    My QS205 runs circles around a QS273!

    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...

    My QS205 runs circles around a QS273!

    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...

    My QS205 runs circles around a QS273!

    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...

    Votol EM-260

    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...

    My QS205 runs circles around a QS273!

    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...

    Votol EM-200 Controller

    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.

    Votol EM-200 Controller

    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 EM-200 Controller

    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.

    Votol EM-100 & EM-150 controllers

    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...

    If you guys wanna see the performance on the street check out the videos of Dui and I against a 400cc bike. Soon another video with the Mobipus 72600. We'll need to find a 600cc for that one! https://www.youtube.com/watch?v=xRTDp5tUqaY https://www.youtube.com/watch?v=IUS4IMGhe3E And this...

    Race: Kelly KEB 12KW vs Sabvoton 200A vs 400cc

    I used every bit of it. I will choose a different geometry for my next build to fit a larger battery. I would go for a Chang Jiang 750 (1930's BMW copy) if I could afford it. Let's see what the future holds.

    Race: Kelly KEB 12KW vs Sabvoton 200A vs 400cc

    Its not and Ebike, its a Magician 250. Yet, it was'nt easy to fit the battery there! I'll make a thread with pictures later on, its just a bit of a hassle to do from China that's why I haven't done it yet

    Race: Kelly KEB 12KW vs Sabvoton 200A vs 400cc

    Yep, Dui has flux weakening and the 400cc has a gearbox! The pack is A12320AH 24s2P for me 23s2p for Dui. 300A Ant BMS
