Jeremy Harris said:You need the sensorless version of this controller, or use this one and add a sensorless module (I have a spare sensorless module for one of these, it's a tiny add-on board that fits inside the controller case). Ed Lyen here sells sensorless, uprated, versions of this same controller, but they are more expensive: http://endless-sphere.com/forums/viewtopic.php?f=31&t=19587
You could email Keywin Ge (a.k.a e-crazyman, the ebay seller mentioned previously) and ask if he has a sensorless version available (I'm pretty sure he will have, as he supplies controllers to a fair few people directly, including Ed Lyen, I believe). The snag with contacting Keywin right now is that it's Chinese New Year tomorrow, with a ten day public holiday in China. This means you're not likely to get a response from any Chinese vendor for a couple of weeks.

Thanks for the reply Jeremy, I thought as much. I have looked at Ed Lyen's controllers but I’m not very technical with controllers so to me it looks quite complicated with all the programming and stuff and I’m not sure i want to pull 20A from the battery (think battery is rated for maximum discharge of 20A and rated at 10A continuous) as i believe it comes set for 20A and I wouldn’t know how to change it anyway.
I think ill email Crazyman and see if he can supply a sensorless version of the controller as I’m sure 15A would be sufficient for kit I have now. I’m not in a great rush as I still have an operational kit, albeit a slow one so I’m looking for something that’s more plug and play for now I think. feel free to correct me if I’m wrong on my assumption of Lyens controller though as I’m sure the added functionality would serve me well down the line but for the minute I wouldn’t know where to start with programming it.
