Hi Tom!

I have replied back to you via PM. Thanks!

Lyen, PM received. You have answered all my questions with real information. You are good guy.
Thanks.

Hi Mighty!

Yes, I would not sell any controllers with potential issues. The potential issue that Steveo suspected is being escalated and reviewed by the engineers from the manufacturer and me. I will get back to you once it is clarified.

Regards,
Edward Lyen

Hi Lyen, in light of SteveO's post, do you mind if I wait until the issue is resolved before I pay you the remainder of the money I owe you for the controller?

Thanks.

PS I am sure SteveO is a legit dude who just wants the best for forumites....

Thanks Lyen. As soon as everything is clear, just send me a PM and I will pay you the remaining 75% plus the postage. Thanks and good luck with everything!

Here is the remedy. I have engaged a bunch of people from the manufacturer for the potential issues that was mentioned by the young fellow Steveo again. I was told by the engineer and designer of the circuit board being used was good as is. But to relief the worrying of people, here are more changes as shown on the pictures below. The R115 resistor will not turn brown. The possible reason was because Steveo operated his controller at 145-150v which was not safe to begin with. The engineer told me the R115 resistor can sustain 15 degree Celsius above normal operation temperature. The engineer has also said switching power circuitry for voltage regulation is embedded onto the circuit board, so the additional VR or voltage regulation circuitry is unnecessary. Resolved.

Hi Lyen, in a PM you mentioned 18 Fet and 12 Fet.

I have a basic notion, more fet's = better.

Is this correct.

How much is the 18 Fet controller?

Thanks.

Hi Mighty!

Here is the link for the 18 FET High Voltage controller I am also selling:

In theory, more MOSFETs can generate more power with less heat. But a properly optimized configuration between battery and motor and price are also important. In addition, enclosure size, range, weight, and battery discharge ability should be consider.

Is that last one still for sale? I'll take it

Hi AmpEater!

Thanks for your interest in the controller. Yes, it is still available for purchase.

how about r12 heat issue?

do you have any photos of the r12 circuit fix... i'm curious to see your fix

Why don't you show me yours first? What do you have to hide? Also, you never show me your browned resistor issue as you said you were going to show me? I am curious to see your fix as well.

Lyen

[steveo]

... I have nothing to hide? ... why would i?.... the resistors are very very small .. but i will do my best to take a photo for you... i think i need a magnify glass for everyone to see... i will try without one...

i have not yet found a proper fix... but my guess would be a higher wattage resistor.

Steveo & lyen I fried my r12 in my 18 fet methods controller its just to small the disapate that much heat. I used a 1/8th watt resistor and mounted it up off the bord and its fine now.

Hi Ario1!

Thanks for getting back to me on your PM. The 18 FET Infineon Controller you have purchased from Methods was built using a legacy circuit board. The one you are looking at here does not have the legacy electronic component such as the LM317 and the 7805 voltage regulators. In addition, I have replaced the on board SMD resistors network to sustain high temperature. Again, I have spoken with a few engineers/circuitry designers and executed what needs to relief the worrying from potential buyer although they thought it may not be necessary.

[geetarboy]

Yes Edward, I am ready for "higher voltage"....can't wait

Here's the latest video from an Italian running his electric bike at 116.8V with the Crystalyte 5305 motor using 32 of Headway 38140 cells in series along with the EC124115 controller. He was running at 70-92 KPH or 43.5-57 MPH. You may noticed the sound from his low speed high torque motor sounded like a jet engine when running at high speed. I have asked for his approval to share the video with us.



Enjoy the video!

What I really want to see is some of these bikes going up big hills. Thats where their true worth is. I want to see some of these volt-guzzlers climbing!!

Can I show you 85-90mph instead? It's coming to a theater near you, summer 2010.

Top Speed is all good. I mean, it is impressive- but I am more impressed by brute acceleration and the ability to chew out any hill not called Everest.

What's your system anyways?

Referring to the video posted.......

116v at 75-120A from only 32 3.3v batteries?

Also they are headways...where is he getting that sort of amperage from??

I believe 116v out of a fleshly charged battery pack is about right. 32*3.3=105.6v & 116-105.6=10.4v over when fully recharged. You can put commentary and questions on his Youtube video to ask as well.

That's true....but what is the C-Rate of those Headways? 10C? If even!!

Also! http://images.villageorigin.com/w/index ... u&z=en&f=1

Will this item fit onto your controller and tell me the true speed etc?

Thanks.

Hi Mighty,

Can you clarify what the connector is for? There are only 6 pins being utilized out of the 9 pin connector.

I don't actually know....it's a speedometer for a regular motorbike.
