Endless Sphere

I would consider buying the controller and cycle analyst as well

Thanks

Hi , I’m interested in the qs205 . What winding is it? 3.5 turn or 5turn ? Or do you know the kv? I’m looking for a high torque version 9.3kv , I’m not interested in the high speed version (14kv ) can you post to UK ?
Many thanks Nick

SOLD to wye

Located in DERBY , UK Selling an Ebike for a friend , it was built up using leftover parts from previous builds and job lot parts recently bought Crystalyte controller ( running in sensorless mode no hall connections required ) and hub motor , (13g spokes ) ( Hi power cycles sticker on the controlle...

ASI BAC 2000 FOC controller , (UK based , worldwide shipping) Ive had this controller for about 2 years its been gathering dust on the shelf never used . I tried unsuccessfully to connect it to my windows 10 computer so was unable to configure it to my hub motor and after some searching for help gav...

Update: Got the controller back from ASI , with a new USB cable which apparently was working for Martin at ASI but guess what ? It still doesn't work on my PC ! Maybe it's me or my PC ? I've officially given up on this controller now , Martin was very helpful but couldn't solve the problem. I've now...

Thanks fetcher that's good to know

Hi Martin , Thanks for looking at the controller and confirming it's working . I'm surprised the cable I sent with it is faulty because it's brand new from reputable large company that import from ftdi themselves (not eBay ) it's the fourth cable I tried , all of then brand new , first two from eBay...

Ok so panic over :D Finally got it working! It turns out my throttle was broke , there was no voltage change on the signal wire . Plugged in an old dusty throttle and twisted it and immediately the rear wheel thundered into life ! :twisted: Charging up the lipo's ready for the maiden ride in the mor...

This is the throttle

This is the other

This is one possible connection for the throttle, I think this controller has two throttle connections , one for the variable regen other for the normal throttle. Edit * this is the 2nd throttle output for variable regen

But now I'm getting another problem the throttle won't work , I seem to have two possibilities to connect the throttle The sabvoton has two connections, one says handlebar the other just says 0-5v I've tried both but no response from the controller, I ran the auto hall map successfully but it won't ...

I'm having the same problems,

First problem was the motor over temperature, which was sorted by shorting ( I also used a resistor in series just in case). the white wire to ground on the hall plug .

Finally my sabvoton has arrived , but I'm getting a motor over temperature system error in the software There doesn't seem to be anywhere in the software to disable this , so it won't let me run the hall auto map . There is a white temp wire in the hall plug , how is this wired , can I bypass this ?

Awesome build ! Wish I still lived in S.Wales got some of the best trails around !
I like what you did with the thermomplastic to protect the controller from mud and spray , do you have a link for where I can buy the stuff?

Thanks

Just tried the rs232 , the com port appears in bacdoor and windows says the device is working properly , the drivers are up to date but still wont work :cry: Now i get a red flash on the usb when i try to connect, looks like a signal is transmitting but nothing received . Ive connected ftdi ---- bac...

I tried both grounds and all baud rates , installed the software several times , deleted the usb drivers and re-installed and the key switch was wired straight to battery + ... Got an ftdi rs232 5v cable on order , ill update my results soon hopefully its the rs232 cable that i need .

Thanks I will try that - I've got the rs 232 on order so hopefully end of the week I can try that also

Thanks cyborg that makes sense about the warning lights, ive tried your suggestions tx to Rx etc etc - still no luck, maybe my controller is damaged ? Ive only tried rs485 on pins 10,11, and ground , also tried pins 12,13 and ground as reccommended by Asi still nothing . So next option is to try rs2...

Here is some more , bear in mind the crappy wiring connectors are only temporary to see if I can get this working

Here's som pics

Yes the green and red lights are flashing on the USB when I click , The first way I wired the Rx Tx the wrong way around because in the software only the Tx flashes and I got a small red flash from the USB , Changed the wires around and now the software shows Tx and Rx flashing and also the red and ...
