Crystalyte Sensorless controllers $150 Weekend Sale

[methods]

I have the new sensorless controllers from Crystalyte. Mine are wired for the real CA so you wont have any trouble

72V 40A
Sensorless (works with any motor - even one with blown halls - great backup controller)
These will take off from a dead stop and they perform much better than older sensorless controllers.

They are fully compatible with the ebikes.ca line:

Throttle
Pedal Assist (not required!)
Ebrake (jumper BK to ground to enable regen)
Cruise Control
Cycle Analyst
Reverse (momentary connection reverses direction)

$200 shipped to the lower 48 States
(ON SALE FOR $150 + $5 Shipping)



Here is the other stuff I have for sale.

and BTW: If you are confused... Crystalyte started producing their own knock-off of the Genuine CA but they made the mistake of using the same 6 pin connector. This connector is not compatible with the Genuine CA.... This product form Crystalyte looks cool but it is all bells and whistles with no meat and potatoes. It does not even measure Amp Hours... TRUST ME -> YOU WANT A REAL CA.

In closing, a disclaimer:
I typically despise sensorless controllers because some times they are herky jerky and they dont take off well up steep hills. These are better than most... perhaps the best available... but they still are not as nice as a true sensored controller. The beauty of these controllers is that they will work with any hub, wired in any order, with or without blown halls. It is the ultimate backup controller and it has good power.

So if you have blown halls and dont want to fix them... or you are looking for a backup... or you just cant figure out the 36 permutations of the hall/phase combo... this is the one.

Do these have a LVC set and is there a range of voltages that it will work with? The one that is on Justin's site is listed as 36-48v 40A. Can the "BK" pad on the board be found easily to do the regen modification?

[kriskros]

would this controller work with a Puma geared motor with blow halls???? The Puma does not work with Lyens sensorless controller... with Lyens the motor spins no load ,but only sort of grun ts under load

Hrm - I believe LVC is set to 55V with these 72V controllers. It can be modified of course
18S lipo is perfect for this as 55V gives 1V margin for the actual 54V LVC.

EDIT: NOT SURE ABOUT LVC LEVEL. NEED TO TEST AS THIS IS RATED 48v - 72v SO 55v LVC DOES NOT MAKE MUCH SENSE
EDIT: LVC is set to 55V - looking into the software to allow reprogramming right now. I prefer LVC to be at 28V....

The BK pad is very easy to find and I can assist you with this.

That is a fine question and I do not know the answer. My suspicion is NO....
If you want to find out I would be willing to sell you one with the promise to take it back if it does not work.

I did a quick search and did not find anything super obvious... my gut feeling is no though.

Ok - I want to move these controllers so that I can purchase more CA's.
I am having a weekend sale - 25% off

I believe i have this exact controller. how do i enable regen? thanks

No regen afaict
thank kenny

Hello,
I use the crystalyte display to modify max current and voltage dropout when switching from 36v to 90v. I'd love to hook up a CA but how do you reprogram the controller without the crystalyte display?

thanks,
Mike

Just wondering,

1) Is this sale still on? (I noticed the weekend is over).

2) What sort of encourages you to think it won't work on a MAC motor? Just the general rough times controlling it? I have recently purchased a cheap generic sensorless [Infineon i think, with a nice clean quality green PCB] that was running my mac motor pretty well (but eventually blew fets twice, because the fets are definitively not 4110.)

Anyway, I ask 1 and 2 because I was thinking about whether this would be a strong replacement.

P.S, If i may also ask - do you still sell surplus 4110s or was that just earlier in the year? I was tempted to put together a 100 fet mouser group buy because i really wanted a dozen on hand, but your scale and price is much better if you're going to be doing another buy in the next 12 months that's open to ES public.

These are not compatible with the Crystalyte display. These are compatible with the CA and they are not programmable.

Just wondering,

1) Is this sale still on? (I noticed the weekend is over). They have been on sale for only $100 on my website for months. Sale is over now tho as I think I sold the last one last weekend.

I hate sensorless - it will run like crap.

This would be a poor replacement. Use sensors whenever possible.

They only cost $1.50 at Vertical. Go to OCTOPART. Enter IRFB4110. Expand the SEE VOLUME PRICING. Compare all the prices and buy the cheapest. Usually Future, Arrow, or Vertical. We just bought 500pcs from Vertical last weekend for $1.50 each

[scriewy]

yo yo YEA YEA hamster on the mic !! i second that Verical without "T" and arrow are kick ass places, it's like heaven, they just got the old fashion handling fee of 14$

but in case you are curious of insanely bad prices use http://www.findchips.com da BOMB

[Kin]

Wow! Thank you for those gems! Much much better prices for the fets. Sorry for being off topic a bit (extra, because my controller inquiry has been given an honest answer of no.)


I quite appreciate the info, however.


{Looks like verical takes like 8 days to ship [Estimated Aug 16th], not on par with my young generation amazon expectations, but whatever. That's good enough.}

Yea... that totally screwed us last week when Matthew ordered 500pcs overnight and missed the fact that they were being drop-shipped from Germany We ended up having to chase the order with a 6:30pm Friday order from Future electronics for 100pcs FedEx, Overnight, Saturday, Red. Got the fets in about 12 hours - but do you have any idea how much something like that costs? You want to talk about expensive fets... but we got our prototypes done and sometimes that is just the cost of doing business.

[bigmoose]

We should start a block pool to guess what they cost you. I'll put $5 on $7.37 ea net.

sad but true....

I went over 13 years without getting more than 2 days off in a row. And that wasn't too damn often either.

It worked out OK as I kinda quit at 40 and my daughter might be on the same path.
