You might want to add something about using the #9 pin relay output to drive the contactor coil, just to clarify as opposed to the standard wiring.
Done, thanks for pointing that out

Re: Kelly Controllers Configuration Program - a Definitive Translation

2. Max battery current. There is written controller limits batt current at high speed. (rated controller current[A]*max motor furtent[%]*max batt curtent[%]) But what is high speed? At which rpm? It seems to me something over 3300. I understood it that the limit is permanent, that is to say the lim...

Re: Kelly Controllers Configuration Program - a Definitive Translation

Unless you tested it and found it to work, in my version, the controller would not power up without a 1v current in the 1-4v mode so you can not use a 0-5v throttle on the 1-4v mode. Thanks for the positive feedback. Have just tested this and can confirm that it throws an error if it starts up with...

Re: Variable Regeneration Voltage Questions.

I don't know about your specific controller, but the one I'm using has onboard variable regen which requires a 0-5v brake lever (or potentiometer). The harder you press the brakes, the more regen you get.

Re: Hall Sensor or Phase wire making my electrics burn? (With video)

Thanks Amberwolf. Unfortunately this controller doesn't provide any kind of live data via it's USB connection. Neither does it perform any kind of data logging. For interested parties, I've started writing a Definitive Guide to Programming the Kelly KBS48101X Controller . An RC wattmeter sounds perf...

Re: Speed control with a potentiometer

Some potentiometers have a switch, you'll notably hear it clicking into the Off position when turned all the way counter clockwise. All of the ones that I have seen have 5 wires. Ground, pos, and signal as normal, plus another two wires for On/Off.

Kelly Controllers Configuration Program - a Definitive Translation

So I recently purchased a bunch of Kelly KBS101X controllers for a six wheel drive mountain climbing wheelchair which I'm building: http://mountainwheelchair.com . This is a great controller which has many programmable features, however, the instructions in the software have been badly translated in...

Re: Hall Sensor or Phase wire making my electrics burn? (With video)

Interesting to note they have a spot for an NTC 10k thermistor (not installed) on the PCB, as well as what is probably an LM35 (populated) temperature sensor. So you can monitor temperature in there if you want to--I don't know if the kelly can do it or not (and autorollback power if it gets too ho...

I've put a clamp meter over the positive lead between the controller and battery and the largest reading I was able to get was 6 amps.

Re: Hall Sensor or Phase wire making my electrics burn? (With video)

Woohoo!!! I found a phase/hall combination which works! :mrgreen: Speed in both directions looks the same to the naked eye. DAND214, as you suspected, now that I have a working phase/hall combination, it has a much slower rpm. I ran the motors in both directions for 60 seconds whilst applying as muc...

Thanks for everybody's input, this is really helpful. Have updated the images in my original posts. The motors are 48v 500w Mac 536hf 1:5 geared motors with a 20T winding (not advertised on their website) 32 magnet 16 pair poles. According to Mac, their rated current is 10a and max current is 15a.

Re: Hall Sensor or Phase wire making my electrics burn? (With video)

I've thought about this since, and as it's a geared motor with a 20T winding, surely it shouldn't have burnt out just in the time it took me to make that video? It's a 48v controller and 48v motor, running off a 16s LiFePo4 battery pack, charge in the battery was 56v. Rated current for the motor is ...

Re: Wiring for Multiple Controllers

If you reduce the resistance, you may need a higher wattage resistor, so it's easier to use six resistors to do it instead of finding one 1/6 the resistance and six times the power level. I did consider using six resistors, but I figured this could cause problems; If I had 6 resistors across the co...

Re: Wiring for Multiple Controllers

Update I think I've come up with the final wiring diagram for the 6 controllers (See below). Essentially, it's exactly the same as the one provided by the manufacturer, with the addition of a kill switch (to prevent battery discharge as per Amberwolf's suggestion, and a fuse). I figured it was bett...

Re: Which Controller (edit: hub motor) for my daughter's wheelchair?

Ye, wheels need to have a larger diameter though and would lose too much torque on those motors which are intended for smaller wheels.
