Re: another pit bike conversion

Had a couple more test rides on this bike now, upped the controller amps to 150 and then realised how completely absurd this motor is for this tiny bike! now dropped it back to 100A and tempted to go further but its so much fun! Received this throttle, And it works great! much better response than t...

Re: Votol EM-100 & EM-150 controllers

@larsb Which manual are you reading from? I've been using the 2000w motor with em100 controller a little bit now but cannot seem to make the throttle response sharper in controller settings, is this just the nature of a low kv motor without reduction drive? I have switched off soft start which helpe...

Re: another pit bike conversion

I haven't done much testing but with the way I ride it i cant see more than 15-20km range Time for more battery then... :twisted: Seriously! I could fit twice the battery i have under the frame and the motor would not notice the extra weight whatsoever, if i did double the battery it would only be ...

Re: another pit bike conversion

Nice build! :thumb: Maybe get a 12" rear and a 14" front wheel combo in that bike if it would fit? Thanks bud! Yeah 12/14 would be far far more suited for this motor although probably still complete overkill, And I am very tempted to build up another chassis in the near future but 10" wheels are su...

Re: another pit bike conversion

So I mounted up the motor, just a matter of making some small mounts - 8 in total and a bracket under the frames top tube to mount the controller too, and then finally I knocked up a basic lower frame mount for the time being to mount the batteries, batteries currently fitted super snug with foam in...

Re: another pit bike conversion

Recently received the 2000w motor with votol em100sp controller combo, decided not to convert my crf50 but built up another cheap 10" pit bike to convert, will probably be damn inefficient but should be a lot of fun!

Re: CRF250 Build

sounds like a great bike to convert to me, the crf150 is a steel frame but a smaller bike too, in terms of frame weight though there really isn't a massive difference between and aluminium and steel frame if that's why you're thinking aluminium..

Re: Votol EM-100 & EM-150 controllers

Just received mine. My usb cable is exactly the same. Blue and orange is crossed in the plug, and the black Wire is cut. Ah ok, not sure what the reason for them switching them is, but it guess it doesn't matter, the colours are wrong but the connections remain the same, it made me believe they had...

Re: QS 3000w midmotor

I recently received the 2000w motor, I noticed someone had water in the hall sensor, is there a gasket on the plate? or only silicone? I'm wondering if its possible to place a paper gasket to stop water getting in..

would there be any other areas on the motor which might need protecting?

Thanks

Re: Chinese Pit Bike Conversion | Nucular 12F | LMX-Motor 60mm | 18s 16Ah LiPo

@ZERONEST Thank you! I thought about that motor too but it would be too overkill for this small bike. Also the size would be a problem. The distance between the two straight arms on my frame is only 220mm wide. With an overall length of 215mm the QS would stick out to one side in order to maintain ...

This is what I found: pin 14 main plug - orange CAN-L/TXD pin 15 main plug - blue CAN-H/RXD have you asked QS for documentation? I have, they sent me pointers, but haven't yet confirmed that I may publish them. But I think you'll find earlier versions along this thread and I don't think that wiring...

Re: Votol EM-100 & EM-150 controllers

thanks for all those newbie questions I did not dare to ask :thumb: regarding the 2-wire: might it be that it is CAN-based, not serial? I'd expect 3 wires (CAN-Hi, CAN-Lo, GND) for CAN as well, bus as some dark remembrance I think I had read somwhere that GND is not mandatory (no warranty on that),...

Re: 18s vs 20s lipo pack build decisions

Ahh, pit bike I'd be tempted to run it on 24s. :twisted: Those are designed for about 40 mph, or more. I replied thinking it was a bicycle, using typical bike hub motors. However, depending on the motor you use, it's quite possible to get 40 mph from a 12s pack. Just depends on the volts and the am...

Re: 18s vs 20s lipo pack build decisions

That's a very interesting conversion, I'm considering a CRF150 sized build so I'll see how yours works out. Which motor are you considering? a Crf150 would make an great conversion imo I would love too myself but am on a small budget! Here is a video of someone converting a cr80 (same size as a crf...

Re: 18s vs 20s lipo pack build decisions

3 6s would be much simpler than 5 4s. But sometimes how the bundle is shaped matters too, for carrying it. Re the extra speed of 20s, consider the bike itself. If it starts to high speed wobble at 35 mph, then you don't exactly need 40 mph. Depending on how you carry the motor, battery, and any car...

great project! thinking of also converting a pit bike myself but running a qs motor 120 70h as it already runs the standard pit bike sprockets to match the rear. also running 18s and 16-20ah, do you have any idea on what range you might get from your pack yet? or too early to say yet? :thumb: :thumb...

Re: 18s vs 20s lipo pack build decisions

18s splits nicely into 6s bricks which fit with common cell monitors and balance chargers. You can do similar with 5s bricks to make 20s but it will need 25% more hardware and each will have an unused channel. yeah 3 6s packs is nice and simple, and also already have a 6s charger although it it onl...

Yes, bumping right up to the max V rating may reduce longevity or even burn quickly.

Amps will only be stressfully high with standing start, uphill, heavy loads, should be fine at 18S.

Ah that makes sense, thanks again!
