I was eventually credited for this kit, and sent it back.  Though this seems to be a mostly dead forum (and I understand why lol), I'm making this post as closure and fair warning for anyone else who might be considering these motors.

Initial sales advice seemed fine, but was eventually found to be wrong.  Tech support is shaky, and customers are expected to diagnose any problems - even on a brand new unit that never worked - right down to the circuit board level.  Overall I give Golden Motor a +10 for appealing sales offerings, and a -1000 for actual product and customer support.

following, as I have the exact same issue, although I my case rhe motor is installed in a boat.

Ah, thank you about the torque base speed control note. Everything is pretty much set to default , and I remember seeing that.  This is very helpful.

I do wish there was a better guide on all the various settings. It's a bit tricky trying to figure it all out only when I'm attached to the controller.

I am using the 3kw version of your motor which I purchased with a Kelly controller and a 'wig wag' throttle.  This worked for about 2 weeks then the controller turned into a brick and the throttle fell to bits.  I had to go over to a Sevcon controller and work through throttle issues.  I finally settled on a Curtis PB6 linked up to a boat mechanical throttle via a cable.

I cannot help with you controller settings but can tell you the issues I had with mine; Firstly I needed to set the voltage band (max and min) the controller expected to see and then a dead point (voltage range within the band) that corresponded to motor off.  The 'wig wag' function also needs to be set.  This all sounds really simple but in practice it took a lot of testing and adjusting. 

Another thing, do you have the controller set for rpm based speed control?  If it is set for torque based speed control you will have no speed control until the motor is under load!

Hi All,

I went with a 5 kW BLDC Golden Motor and the matching controller (EZkontrol 48 Volt Universal BLDC Motor Controller, 800 Amps), but I'm having difficulty figuring out the throttle controls. We've rigged the boat's mechanical throttle to a Curtis PB-6 style controller (so it is a potentiometer style). It takes a lot of travel before the motor kicks in, and it goes right to 4500 RPM and doesn't change no matter how far along I go. Is there an easy guide to figuring out how I need to change the controller settings? I'm having issues even seeing what the options are unless I'm connected to the controller via bluetooth.

Any guidance on how others have programmed their setup would be appreciated

That's very interesting, considering I was told very specifically by Daryl at Golden Motor that the Magic Pie 5 could not be operated on an EGO battery.  He literally called me and told me Zar was wrong, these batteries would not work with their product. 

He also claimed to be the owner of the company and told me he would credit my card as soon as the return label he provided was trackable.  I'm certain I am dealing with someone  in the company (I initiated the emails and calls), but obviously things are not as they seem.  I'll investigate further!

I have no idea why Daryl at Golden Motor is giving me bad information then, it is clear that the unit WILL work on 14s batteries! 

Daryl claimed to be the owner of the company, it looks like I need to research a few things!

Golden Motor has now responded, and told me that in spite of their prior guarantee - which I based this whole build on - their Magic Pie 5 will NOT work on 14s batteries.
The Magic Pie 5 will definitely run on a 14S pack without any problem as the maximum voltage is well below 63V. Even the earlier Magic Pie controllers (which were limited to 60V max) would run happily on a 14S battery pack that was charged to 58.8V.
My GM rack mount battery pack contains 16 LiFePO4 cells which are charged to 3.65V per cell (58.4V for the pack) and has been used for testing at least eight different versions of Magic Pies & Smart Pies:



I have run Magic Pies on fully charged 14S LiPo packs for many years without any problems, and back in December 2014 I even ran a Magic Pie 4 on a 15S LiPo pack with a voltage of 62.53V to confirm that it would work, so your 57.7V battery should have worked.

As your MP5 did not even work with a 47.5V battery there must be something wrong with the controller or wiring/throttle etc. as it is should have definitely run on this voltage.

Why would Golden Motor sell 52V batteries (which have exactly the same fully charged voltage as your EGO 56V battery) if the voltage was too high for their controllers?

If your motor kit was in good working order upon arrival (and the controller and wiring etc. has not been damaged during installation) then it should work fine with your EGO56V battery pack.
