12 x 4110 MOSFET Extreme Modder Controller LYEN Edition $129

PM sent

He probably doesn't know, the only control mechanism on these is the shunt feedback which is battery current. It's not easy to measure phase current, let alone specify it in certain limits.

He does like to send information directly though, I've noticed that. Good guy though.

Endlesssphere is about helping each other. And knowing phase amps for a controller you are trying to sell to make money will make you more money!

I'm a bit put out with this PM nonsense too.

Good evening Gordon,

I'm sorry for the delayed response due to excessive workload. I am trying my best to answer PMs and emails in the order it was received. I preferred communicate via emails and private messages because it is more productive to follow up with individuals. I have replied to the emails you have sent.

*** Clarification on commentary made by Gordo. The wiring diagram was already labeled on the bottom of the controller he purchased. In addition, the color coded wiring instruction was also provided. I do provide assistance on troubleshooting if needed.

Sincerely,
Lyen

Does anyone know what type of waveform does Lyen's 12 FET motor controller produce? I don't have access to oscilloscope for now so if anyone knows, kindly inform me as I need to include it in my thesis paper. Thanks!

Are you asking if its a sign wave? I belive its just block comunication. These controllers are pretty basic!
Which is a good thing BTW.

The throttle is based off a reference voltage,right? So outputting 4.5V to controller will return 0-4.5V and not something less... I don't want to lose a few mph cause the throttle isnt outputting full throttle. What happens if you input a voltage Into throttle sense... Say 1-2V over common 4.5V max?

[nicobie]

The controller will cut out if it sees under or over voltage. Safety feature.

[hillzofvalp]

With beefed up traces, the 3500 W limit on controller still remains, correct? So I could not run 90A at 46.2V but 75A will be okay?

im interested in one or two of these, but I want to start out using a 36volt system and later would like to upgrade to 48v or even 72v later as money comes in. Is this fairly easy to do? are there instructions? or can I have them preconfigured?
thanks,
August

Just get Lyen to set the initial LVC (low voltage cutout) for 36V, after then you can run the higher voltages as you like. If you want you can always set the LVC higher (but you don't have to do that) if you want a higher LVC. Make sure you get the programming cable with it when you order it, as you will definately want to program it later, and get the CA attachment and a Cycle Analyst (if you don't already).

These are a great controller for your purposes (ie starting at 36v but looking to go to 72v later), and allround great controller, Lyen is the man. Cheers, Phil.

I got the controller in the mail today. Unfortunately, none of the connectors from the Ampedbike wires match the ones from Lyens controller. All of the connectors would have to be replaced.

Yes, there is no global standard for connectors, so that is how this hobbie works.

[shock]

Just got mine, quick and quality, same as the 6 FET I purchased.

Lyen includes everything necessary to hook it up. It has all the spades and connector shells to put on an existing kit.

Please PM me the max phase value also. Likely not going to push it even close, but as a new owner I would like to know. Thanks you Lyen!

Phase failure on 12 fet will occur around 150A

[GCinDC]

Phase failure on 12 fet will occur around 150A

great to know! at what voltage? and after how long?

[ohzee]

I have been running this controller at 24S 50Amps for some time with no issues what so ever.

very much love it to date

[kevo]

Lyen,
Have been using your controllers with much success Keep on keeping on

I accidentally ran a bit too much power on my 12 FET Lyen... I just calibrated the shunt and plugged the CA in to see how much power I was running for a few days.



That's probably why the front end wouldnt stay down. Whoops.

Amp max and phase amps and battery amps are all different things. Amp max is just a spike and during the spike if you were to watch the CA and see what battery amps were you would see something ~3x less then the spike. For instance look at my avatar it was just a spike and at the very second I got that spike I was watching my CA and the battery amps were 148! I don't think your spike is anything to worry about. If Lyen did ok on that 12fet with 4110 mosfets you can run up to ~120 phase amps and ~60 battery amps. I think I ran mine higher last year to prove it could then backed it down a bit before giving it to my brother.

[ZOMGVTEK]

I was seeing 130-140A off the battery for a few seconds during WOT acceleration. Its unclear as to what the phase current was, but it was programmed to 120A, with the shunt at 1.1mohm. That's probably comparable to a 250A phase setting given the shunt resistance this controller expects. Block time was set to 0.1s, it was hard to keep the front end down. The battery was also sagging like crazy, it was resting at 94.xV at the time. It definitely was pulling serious power.

This controller ran at 80A battery, 180A phase settings for over a year now. Peaks were in the 90's, most of the time it pulled 82-84A at low speeds and tapered off. I'm going to try running it at 200A phase, 100A battery. It wasn't even getting warm doing repeated 12kW WOT runs. However, with the 5404 it got up to full speed quickly, so it wasn't pulling that power more than a few seconds at a time.

[hillzofvalp]

If you can make the heat go away quickly then you'll be fine. the legs of the 4110 aren't to be pushed passed 75A (x2=150) or they become very very saturated and therefore hot. anything that gets hot that is in very close proximity to the fet will likely cause internal failure.

But please let me know how it goes

[ZOMGVTEK]

I made it go boom.

It made it a solid 10 miles or so of reckless abuse at 12kW. I'll check out the damage later, but it looks like a single FET leg went short.

I love it You should fix it and try 11.5 kw....
Then 11 kw, then 10.5 kw... and keep going till you find the sweet spot.

A little tip for the controller moders out ther. I use copper pipe to build my traces up and NEVER cut the legs that carry the current. I wrap the leg around the pipe and leave the ends of the pipe open so they can conduct heat away as good as possible. I also let a bit of solder leak through from the bottom of the board to the fet body to help fatten up the fet leg. But becarefull because it will melt under extream testing and make shit go boom!
