CRYSTALYTE 72V 50A digital BLDC LVC (NEW)

[PowerPedro]

Selling 2 never used cystalyte motorcontroller (72V50A). I bought it 2 years ago and never had the time to build a bike around it. It comes with extra Battery cable and PAS sensor and is located in Vienna/AUSTRIA. I can ship it everywhere. The price without shiping for one unit is 100€

Hi! What mosfets type and count does the controller employ, 18 x 4110?

[juankixote]

would this work with a 48v motor and battery?

[miuan]

very unlikely. the LVC will be about 60V.

[NeilP]

I will take one definetly if you can do two things

Could you do me a favour, and open them up and check the model number on the board. if you remove tthe 4 screws from the end with the switch and key hole, you should just be able to make out the number on the top component side of the board.

Like this..see the number to the right hand side of the picture..

Will be something like EB218 - X -X

I woudl like to know what the X's are....I need a controller and woudl take at least one off you.

No wiring needs to be disturbed or removed or cut for this


If you were prepared to do a bit more and were prepared to pull the complete board out then we can also see if it is 4110 mosfets and 100volt capacitors. And the important bit for me, is what the MCU chip is. If it has a small dab of red paint on it then it can't be programmed, or fitted with a programmin lead.

To do that you need to take the row of screws off the side, and also the 4 screws from teh end where the wire is.
The board with wires then pulls out a little way, enough to see the mosfets. You can usually do this without needing to disconnect the wires from the on/off switch and reverse switch ( the key)

Want to see if the chip, like in the next pic, has the red spot

Does it have a Cycle Analyst connector? or programming connector?

LVC is probably 56 volts...I have very similar controllers from Xlyte and they are marked 72v 48 amp and 56 volt LVC

[Trackman417]

Does it have a CA connecter on it?
What is the estimated shipping to the US?

[nicobie]

Be careful. The newer controllers from Kenny have the same connector as the CA uses BUT it will not work with Justin's CA. It works only with the weak sauce meter from Clyte.

Ugh that's so annoying! I like the Infineon based controller I got from ebikes.ca but I don't like the fact that it doesn't have a three speed switch. This controller would be perfect! You know about an mods that will make this controller work with the CA?

[NeilP]

As the OP says in the first post, bought 2 years ago, so very unlikely to have a Crystalyte APM plug

If it has a plug at all it probably is going to be CA compatible

Easy enough to fit the wires for the CA if not

Same goes for the three speed switch. Easy enough to fit the wiring for it. It just then depends if it has been programmed for 3 speed ops

But going on my Xlyte controller, the plug with yello heat shrink is the 3 speed switch

[PowerPedro]

The Board serial number is EB218-A-2. Low voltage cutoff is 55V. It has original 18 x IRFB4110 FETs. Sorry but i don´t want to disasable it more to check the mikrocontroller... Shiping to USA will be less than 30$
I don´t know about CA compatibility?! Any more questions

[knoxie]

Anyone looking to buy, These controllers wont work with BMC or MAC motors.

[NeilP]

The Board serial number is EB218-A-2.

Damn shame that..I wanted one of the other boards EB218-AS-1..the A-2 version is not programable
But with a shunt mod it wil be good for up to 100 amps.
They are already good for near on 100volts, the 4110 FETS are good for it and the caps are going to be 100 volt rated too

Just wanted to suggest: Having a current limit switch shouldn't be that difficult. Assuming that you can do a shunt mod to decrease or increase the current limit, than you can shave down the shunt 2/3 of the resistance, then run two switches to some form of resistance allowing the the next 2/3 of the resistance go through (you could do this same thing with a three point switch).

However, my assumption is that "three speed switch" means "three power level switch." If it's actually limiting your top-end somehow, then I don't know an easy way to emulate that effect.

To OP: Sorry for the semi-hijack.

hello.
Can this controller to work on the magic pie 2 motor?
do anyone know what to expect?
is difficult to connect ?

[NeilP]

I do not know if the magic pie 2 has hall sensors or not but if it is, then yes, it will work

Wiring is a matter of connecting up the phase wires colour to colour, and the same for the 5 hall wires. Then testing with small throttle movements and the wheel in the air..no load. You may then need to swap wires around to get correct rotation. So to protect things in case you have the initial wiring wrong, here is what you do:
Connect just controller, motor, throttle and battery, no other accessories like CA, brake levers pedal assist, cruise control speed switches etc. Connect battery via a low value fuse for initial testing (5 or 10 amps will do). If you had a 10 amp ammeter, then you could connect that as well to monitor current.

You then open throttle gently and see if motor spins smoothly with a low current ..1 or 2 amps max. If not then you swap wires and try again. There can be a lot of swaps to do...a maximum of 36 combinations...but usually you will get it within the first 5 or 6 combos. If you do get it then post back in a new thread and someone will help you figure it out..or just search the forum and you will find many threads on how to do it

But all of that is along way off just now...so if the Magic Pie 2 has hall sensors, then yes it will work.

[miuan]

What about regen? Since the controller is not programmable, it's hard to say but I suspect both throttle and brake regen are active when BK is shorted to GND.

[PowerPedro]

I am sorry... i don´t know that!! Maybe someone else can answer this?!

[dermot]

Does this have powerpoles for phase wires and the (so-called) mini-xlr for hall connections such that it will fit an X5 motor?

Is the LVC cutoff of 55V adjustable? I'd prefer to get it down to 50, since I am using 20 series of LiFePO4.

And finally, is the PAS mandatory, or can it run without?

dermot

[NeilP]

No idea about plugs, but if you are planning on buying a motor and controller seperately and you can't solder and change and fit your owns plugs, then you do not stand much of a chance to get the bike to work. The connections for Halls and phase are irrelevant, you only haves slim chance that they will work as they are wired anyway

LVC. Will not be changeable if it can't be programmed. But the fact that they are not programable is not 100% certain. It is very likely, bearing in mind the board number, but not impossible that it could be fitted with programming lead and attempted, but the ability to solder and work on the PCB would be required

PAS not mandatory, it will work just fine if left in connected

[NeilP]

Regarding LVC
To be completely accurate in my answer;
It would be possible to alter it, without programming, I believe, but this again would require delicate soldering skills. the ability to change components on the board, and the understanding of the electronics involved in order to calculate the values of the replacement resistors

[dermot]

Don't have any circuit notes/diagrams for the later Xlyte controllers, but have done plenty of SMD build/repairs - it's a fiddle, but a steady hand and my pair of binoc magnifiers makes it achievable - once I know which components to change.

I was wondering if it had a keyswitch on the side (not seen in the photo) to change to lower voltage as several of my older controllers have.

Oh I can solder and change plugs all right, just I'm out of stock of the 5pin mini XLRs right now and blew up my current controller yesterday (2 of the 3 filter caps dropped off the pcb and the third one split due to excessive ripple current I suspect - cleaning goo off the board hasn't resurrected it), so want something to just drop straight in to my existing X5, since I'm having odd intermittent problems with the Lyen controller I had as a spare.

dermot

[NeilP]

Ah well, ok then.

I did have some notes around here somewhere that I had pulled of the threads or some of the controller info pages on how to lower the LVC pretty sure it is just a resistor change..but just can't put my mouse on it today. possibly more because I seem to remember that these earlier controllers derived their power from a resistor divider network as opposed to a switch mode setup as I believe the later boards have.

I already have one of these boards, but only run it on a test bike at higher voltages. did try adding a program header..but as noted earlier..it looks like the 'red spot' MCu's are not EEPROM style just factory written one off chips. Just waiting a big 300W soldering iron to come down, to re do the phase and battery wires to at least 8 gauge, and solder the shunt up, to see what i can get out of it

[Trackman417]

Since its CA compatible you can just set LVC on the CA and it will limit current accordingly.
Problem solved

No you can't..not to bring the LVC lower..the CA could make the LVC higher..say 72 volt..but van't make it lower..you would set the CA LVC at maybe 40 volts..but the controller LVC of 56 is still there

Yeah about that
Well something is better then nothing. Can you agree with me on that one at least? Lol
