Finally got the QS hub motor moving with temporary wiring. I encountered a couple of issues here and there but luckily I managed to reach out to a Mr. Powell in the US that has a leaf cell / Kelly controller set-up that is similar to my own and hey presto, the hub finally lives. Just needed to put it into forward mode. Really enjoying learning new stuff from folks in the eMoto community.
Although this is a momentous moment to treasure there is still a fair distance to travel to get a working powertrain. Still many calibrations steps to make but a good start.
