Welcome back Trond, unfortunately as MM already mentioned, you're not the only member who has lost their account.
I've been trying hard to find out how more than a dozen user accounts could have disappeared for no apparent reason during the past 4 or 5 days, but I cannot find any logical explanation for their disappearance.

If it was caused by Gremlins, I hope they've gone and don't come back again.

Has enyone bought seperate internal controller from GM? How do I do that? What price?

[Andrew]

i think they are about $33.00 USD on the GM website with the option to pay with Paypal, but then you will have see what postage they want to charge. go to the paypal checkout and it will tell you postage cost.

[Bikemad]

The $33 "PI-0200I internal" on the website refers to the USB Programming Interface cable, not the controller itself.

I suggest you email sales@goldenmotor.com (or possibly tom@goldenmotor.com) and request a price for a replacement internal controller for the Magic Pie.

Exact same problem on my Pedicab with one month old 901 front hub using the Golden Lithium Battery 36V16A. Tried two different Anderson connectors, but problem remains.  

Specifically, on start (even without load) motor cuts out if throttle is opened quickly. After about five seconds will work if throttle is opened very gradually.

Once in motion, motor cuts out under load (hills) at low speed. After about five seconds it will work if load is decreased either by peddling hard first or changing gradient.

[Trond Jacobsen]

Yes, same problem. Please post if you find a solution. I will. I will send email to GM about buying controller.

Hi Pediman

Perhaps you should also contact Tom if you have not done so already.

The controller low voltage cutout would turn back on automatically, so if you are resetting to get the power back it sounds like the battery BMS is cutting out.

What voltage do you read from your battery terminal?

Email Tom tom@goldenmotor.com and explain you are experiencing this and steps to take next as you may need to test your cells.

I'm sure your pedicab customers would be wondering whats going on when the power cuts in and out!

good luck

Hello Pediman

Maybe this theory has already been floated but it sounds like a 36 volt battery running a controller set at 48v. Do you have a USB cable?

[Trond Jacobsen]

No answer from GM. Considering Infineon 40. Easy to install? Does the Infineon need programing to work with MagicPie?

Sorry about that,  I miss read the GM website

More useful information can be found here regarding the conversion from internal to external controller on the Magic Pie.

The Infineon controller does not need to be programmed to work with the Pie!

i really hope internal controllers are available to purchase    I now have two of them, and am prepared and am slowly working upon my skills and understanding to eventually change one if neccessary.
