Bit of and update,

Have been able to get some support from far-driver and Redsea. Thanks.

They have both basically told me the controller is bricked. Far-driver has offered to get the controller repair at the factory or cut me a deal on a new replacement.

So I have swapped the 360 for the 530 in the KTM85. They are both the same size apart from the heat sink. It’s 15mm solid aluminium on the 530.(10mm on the 360)

Software is still buggy. Constantly reconnecting and a few fields that simple will not change, for example the pole pairs is stuck on 4, was able to change it to 5 on the 360. I believe this only effects the rpm gauge.

So the 530 is up and running connected to the QS120. Currently turned down to 160/300A
A few short test rides, acceleration, FW, regen all feel good.
My boy is in a local MX race day tomorrow, would of like more time to do more testing and refinement of settings.
Straight in the deep end.

Will report back Monday.

Glad you got some answers. Will be interesting to see how it goes with the ktm85 and the 72530. Will wait to see what you have report back after the weekend.

We have about 3 hours on the 530 and so far everything is going really well.
Saying that, it’s only operating at a bit over half capacity, so I would hope there are no problems.
It’s set to 160/300a from its max of 330/530A.
Heat sink with my crude measurement technique only got 5 -10 degrees C above ambient.

Still don’t know what I’m going to do with the bricked 360.
The App does have a ‘FLASH’ function. But I am unable to get the Filmware out of far-driver.
I may pay the $100usd they offered for a replacement and then tear it open to have a look at the internals.

I am building a battery for the 800A model right now. I'll let ya know how it goes.

I am thinking about buying that one. 1800A phase sounds fun.
Any update on this controller? I’m considering buying one and it seems like most of the reviews are positive, would love to hear your feedback!

NO. Last battery I built for this guy took 6 months.. for I am a very busy person at the moment. I will update. I was think ing about buying one soon though. I had a chance to buy a Nuclear but he wanted more than my 800$ offer so I am taking that money and buying something else.

I got a couple of ND72330 rated @ 150A and I would say they work quite well - Very easy to configure. They provide an auto-learn features to accelerate the initial process. So far so good. For the price (approx. 150 euro/each) it's a fair product.

Need more time to say how it goes in long term

Interesting. Do you use the phone app or the computer program?
No problems setting up the motor temp sensors?
It seems to only have fixed regen right?

I used the mobile app that looks to have all configs available. The PC software is only partially transalted in english....
Standard NTC temp sensor, no problem. The wiring harness provides typical plugs for this kind of controller (low brake, high brake, key, 3-speeds, cruise and even a sound allarm output).

I've not yet tested the regen brake yet.

Are anyone running this controller successfully on a qs138? Im currently running a votol 72150, but am honestly tired of figuring out of all the bugs and different versions of software and firmware. Currently it is running OK, but looses sync above 4500rpm, and lacks some low end grunt... Is this any better to set up? Eg, does the parameters do what they are are supposed to do according to manual and name? That would be a fantastic upgrade over the votol!

Hello everyone. I am planning to buy fardriver controller nd96530. I got qs 205 v3 55H 4000 watt motor. My motor laced into 18 inch wheel. I am planning to reach 130 km/h top speed. My battery max voltage will be 116 volts. What do you think about my setup? By the way, seller told me that flux weakening feature helps me to increase top speed. Is flux weakening really works on this controller?

Yes, far driver controller can work with flux weakening.
The setting also related with the RPM of the motor.

You can tell your detail requirement that before shipping we can do the setting for you.

Up to which voltage does regen braking work with the 72800 / 72850 Modell and with the 96850.

My Sabvoton 72150 with max 95v does regen only up to 85v.
I do not want to buy a controller with which regen works only with lower voltage. I have a 21S battery.

This lowering of the activation of regen is to protect the controller from voltage spikes that can damage it. It's reasonable that this restriction exists at voltages close to the component rating.

He is completely right. Generally %10 voltage spikes could happen so controller supplier arrange max voltage according to that.

If this is really needed than the ND72XXX range will not be enough for my 21S battery when regen starts at approximatly 80V.

I ordered the ND96850.

The 72x is rated for 88 max so I guess it's safe to say that regen would work with 21S right off the charger. The 96x was superfluous imo.

I have a 138 90H I am not sure which controller to buy the Votol em260 or the Far driver 72850. What is your opinion which one would be the better controller? I'm particularly interested in the flux weakening function. I had a sabvoton 72200 but it was very bad because it didnt have a high enough rpm. As far as I know the no load speed for the 138 90H is 6500 with the Votol at 72volts. Can the far driver do this? Can it reach the same rpm as the votol? Can you match it perfectly for the 138 90H so I get the 6500 no load RPM?

Thank you!

My Sabvoton 72150 with max 95v does regen only up to 85v.
Superflous was to kill a new SVMC 72260 and a new 72150 with no load on the main stand with activated flux weakening.
The SVMC 72260 is rated with max Volt 90 and the 72150 with 95V. Regen on the 72150 starts below 84V.
For me more max volts on the controller side means more safety while playing with parameters.
And I have a few cells left to raise the battery voltage. :wink:

Is the controller FarDriver suitable for the cyclone 3000w motor? Maximum current is 40 A, voltage is 72 V

I have ND72530 controller, does anyone know anything about UART serial protocol used in this controller,
I want to read UART data and convert to CANBUS messages.Listening on UART port with 19200bps connected PC I am receiving AT+PASS=35271949 message continuously.

Just saw the new Far Driver ND2400 series controllers. That is some serious specs for the DIY crowd!

Hello guys,

I bought a fardriver 72530 and QS138v3 but I have a lot of problems setting it up. When powering the controller it says temps sensor and a throttle error.
When I set the temp to O and do the Auto Learn the beeping stops. But then the real problems begin. There is almost no power.. First the rpm rises to 4000 and goes back to 490. And then its stuck on 490 rpms. When I try to change anything the Ratio in Speed settings go to 1% on every setting. And I can’t change it back to what it was.. I really have no idea what going on. A little help would be appreciated! 🙏🏼

Regards,
Mike

Hi! Firstly go to ratio speed and put 100%, 99%, 98% etc, then without saving this parameters, do the Auto Leaning. You will see that autolearning on this way will accelerate foward and them reverse. Finishing the auto learning, turn off and turn on your scooter. Now set again the Ratio Speed parameters and then save. On mine scooter with ND72330 works well on this way. Hope it helps you

I am pretty sure the qs138 v3 has 5 pole pairs you have 4 pairs entered. And also maybe change your rated speed to 4000RPM.
