QSMOTOR, do you plan to alternativiely equip your MID motors by SINCOS encoders instead fo halls?

Yes, for our new 180 90H 9000W mid drive motor we will use encoders instead of hall.

Is that.. a Microcar?!
I need to see this thing on the road please.

That's pretty cool :thumb: I'm guessing it's not road legal though?
Are you really just running 3Kw through that beast motor?
The display in the engine bay is quite hilarious :lol:

I wasn't pointing out that it was illegal, rather curious if you would try to make it road legal.
Still, cool project mate :thumb:
I just bought myself a Fiat Uno for 50€ and after I run the engine dead I want to convert it to electric.

Hi
I have just purchased this motor (and the Votol EM150SP controller) to use in a 85cc dirtbike chassis.
What kind of battery would you recommend for maximum output of this motor? Power output and weight is prioritised. Run time not so much.
LiPo/Lifepo4...?
Voltage?
BMS max amp?
Link to a specific battery!?
Any help would be much appreciated.

I run 200A battery current at 72V and it pulls well 
I’d aim for this.. but spec can offcourse be lower also.
Lipo if you want this current and low weight.
300A smart bms from icgogogo at aliexpress is good. There’s a looong thread on it here at ES.

For this motor and controller you can use 72v 40Ah lithium battery, which can bear max 150A current.

I got my QS138 3000W motor and Votol EM150SP controller yesterday, I'm very exited to start building!
I think that I will go the LiPo way for my application since weight and size of a battery is a major factor.
The 300A BMS that larsb recommended will suite my needs, thanks for that tip larsb!
After some research I found that it seems that 6s batteries are much more common (and cheaper!?) than 5s batteries.
The original plan was to go for 20s 74V (4 5s batteries in series).
Would it be possible to go for 24s 89V instead (4 6s batteries in series)? Or would that be to push my luck a bit too much? The bike I'm building will run on small tracks and I imagine the longest full power bursts will last approximately 7-8s.
I look at batteries like this one:

It will blow the controller if you have the 72V.
24s is >100V which is above the component ratings

@icecold:
So then go 3x 6s for 18s LiPo or 5x 4s for 20s LiPo:

There are usually 4s packs too.. 2x4s+2x6s makes 20s
hello I can not unscrew the nut of the engine pulley. Do you have a technique? I use an impact wrench with a 24mm socket and I left the strap on the transmission to prevent it from turning. I tried several times without success. thanks for your advices

Could it be left hand thread? Did you turn it the correct way?

If it is left hand thread you'll have to turn it clockwise to loosen it. But I don't know if it is LHT so someone who is certain should confirm (or deny).
