9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

[Frank16]

I can't figure out if it is possible to connect BOTH a (digital) PAS sensor AND (a throttle OR a 6 position LED controller panel)

My current 250W standard controller allows me to turn everything on, step on the bike and paddle away. The PAS then turns on the power to the motor and a 6 position control panel sets the cruise speed. The Infineon type of controller seems to work differently and I can't figure it out.

Any help welcome.
Thanks,
Frank

i think i read you saying somewhere not to try programming a controller if you don't know what you're doing. is this true? if so, what knowledge is necessary to program one of your controllers? i'm new to ES but have read a lot of people that are using your controllers. another plus is that you use infineon and they are the best for waterproofing. i live in seattle and that is very important to me because i have to ride rain or shine.

Does anybody know how to connect the ignition switch to this controller?

Loose red wire looks like the one to connect to switched power from battery +

When I bought this controller a few weeks ago you said on your original post

I have only 30 made since I am busy working on my other ebike projects.

Now it says

I have only 33 made since I am busy working on my other ebike projects.

Are you willingly deceiving us to sell faster?

Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed.

Lol. So he had time to finish 3 more even while he is busy working on his other ebike projects. That wouldn't be scamming... And by the way I think the limited edition scam works better the other way where you lower the amount of items in stock so people think they have to really hurry to get one.

I would say you got it all mixed up there. And you got your product at a price you were willing to pay so what's the problem anyways?

You seem very defensive, did I offend you in any way?

Having gotten around to make small number of extra units is a valid excuse.
And I never used the word 'scam' because that would be absolutely the wrong word for it, just misleading marketing.

[Boeckstyns]

No no. Not defensive in any way. I just couldn't understand the problem. And had a bit of spare time to write a meaningless post.
No harm intended. Cheers

On the positive side I may inform that I tried the controller on both 36v 12s LiFePO4 and 74v 20s LiPo and you can jump between them without changing anything and that is neat. I'm also glad of course that the 9Fet is still for sale because it is a good controller that kept cold while pushing 3kw into the SmartPie until I had to stop in fear of burning the motor (reached 110'C inside the motor).

The shunt value seams to be off though.

[k-harvey]

could one work on 24v cyclone 500w+ as the internal ones often fail, 3 out of about 9 that i suplied .Also then theres the throdle to make fit

[k-harvey]

& does price include a throttle or freight & there is no spell check that i can find .

Seem to remember that Ed gives you a shunt value based on the value of the manufacturer given value. Off the top of my head, I think they are 4 MilliOhm shunts, so 4 in paralel will give you a quoted value from Lyen of 1 MilliOhm.

But all things have manufacturing tollerences, so if you are setting up a CA with the shunt value, then using 4milli Ohm per shunt and workign out your value based on the number of shunts will give you the 'spec' figure.
Depth of the shunt inserted in to the board, amount of solder flow up the leg, manufacturign tolerances will all give a fractionally different value.

If you want it more accurate then you will need to experiment yourself, with an external current reference.

Thanks, quoted shunt value was 2mohm but I think actual value is much lower. I will do a comparison with my Grin Tech shunt when I get the jst-sm plugs I'm waiting on. And maybe also do a comparison against my multimeter.

[lollandster]

I have now measured the shunt against both the precision shunt from grin tech and my multimeter and I'm positive that the actual shunt value is 1.36 mOhm

[NeilP]

How many shunts in parallel in the 9 FET? have not had a 9 FET controller.

[lollandster]

The controller isn't in a position where I can easily open it unfortunately. Last I opened it I forgot to take a picture.

[NeilP]

No worries.

What i meant by 'Stated value of the shunt" was the nominal value of each individual shunt wire. I think they are produced as 4milli ohm shunts..so two in parallel would make about 2 milliohm.
But it only needs for them to be inserted a bit deep in the board, or for the solder to creep up them a bit, / between them/ manufactuering tollerences to reduce the 2 milliohm nominal value, I guess should be the 'correct value' to the 1.36 you measured.

Just found an e-mail from Ed lyen about the shunt values..and yes..4 Milliohm per shunt wire

The is a total of four shunt bars inside the 18 FET controller connected in parallel with the value of 4mohm each. 4mohm parallel 4 shunts = 1mohm.

I think it would be useful, even as an optional upgrade, to include the ability to have a brake light turn on/off when the ebrake is pulled. Allowing a brake light to function like a car's brake light does.

[NeilP]

Not possible I believe without external circuitry, these boards, I am nearly 100% sure, do not have this option on the board itself. YOu will need to do it yourself externally. This goes for all the Infineon boards, as far as aI am aware

[Secret1511]

I have the Lyen 9 fet and i am running it at 50amp with a 12s2p lipo 25c.
It's a monster! 35Mph flat. The controller is getting warm but not hot.
Lyen did a mod to it.

Lyen what is the max. amps i can run it?

Just connect the neg. supply wire of your brake light to the yellow brake wire, and the positive to an external supply with common ground with the controller, it should work. Don't pull too much current though, most brake switches are rather tiny. Alternatively, use a relay or fet to switch the light power on.

Do this contoller support the cruise function ?? Cruise fuction of my controller do not work.!~
Of course, I configured the cruise time to 1 second by the pc program.

[Mic]

Is it possible to program the LVC to 59V ? (at 18S LiPo)

You can select LVC in 0.5v increments between 19v and 66.5v according to the software.

[Allex]

Guys, where can I download or see the default values for this controller. I am trying to use the software
