Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

I'm currently using Xnyle's 'X4 throttle' branch which, as previously reported, works extremely well for me. There's just one small issue that's bugging me though - the calibration of the battery bars. (12s lipo, LCD3 display) It was always possible with previous versions to calibrate the battery ba...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

@geofft Thanks for the report. How did you find out about that branch and how to use it so fast? Did a little bird twitter "coke" down from the stance? ;-) Nothing so sinister - simply down to me lurking on the German pedelec forum and relying on google translate.

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

@Xnyle,

I've just tested your 'X4 throttle' branch and can confirm that, for me, it works faultlessly. Certainly better than my cobbled up torquesensor and throttle wired in parallel method...

This Torquesensor with throttle override option is perfect for my needs, many thanks for your efforts.

That pedals will not work for the ones that do mtb or road bike, because everyone uses the clip pedals. I think the sensor on the cranks would cover almost everyone. Hmm....good point, I hadn't thought of that. That's a shame because I got a reply from them saying they come with a receiver unit tha...

Re: Bafang BBSHD BBS02 mid drive -- Flexible OpenSource firmware

The Kunteng (S12S) type controllers would have a lot of advantages and make life much easier for the developers - if the size can be reduced a little these seem like the best option. I see that PSWpower are now marketing a "20amp" version of the KT36/48svpr (6fet), I'm wondering if for the lower po...

Re: Bafang BBSHD BBS02 mid drive -- Flexible OpenSource firmware

I was looking again to the S12S motor controller I have here. The case says 40A. This controller is big but the PCB uses about 2/3 of the case and I think I can cut with a metal saw the 1/3 and let the case to be smaller and lighter. S12S has the advantage that there are versions up to 72V at least...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Hi, using this firmware, can I reprogram my 12 mosfet controller to a lesser amperage? I think the version I purchased is too much for my battery, but not entirely clear yet on why. Like could I limit it using the amperage setting to 20 amps? As long as your controller is a suitable type for the fi...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

For me there are just two situations where you need throttle capability in the (current) torquesensor mode:- 1) Pulling away quickly from a standstill, 2) In awkward 'feet down' situations where you are manoeuvring at slow speed around obstructions. For instance allowing X seconds of throttle withou...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

If you don't want so much power dissipation/heat you could replace the linear regulator (resistor/LM317 combination) with a 15V buck converter such as the CUI V7815W-500. I did this on mine (ignore the TL783 stuff, I went for the buck instead). https://endless-sphere.com/forums/viewtopic.php?t=7976...

There seems to be no inherent problem with vibrations with this motor (Q128H) and with my current settings it pulls smoothly and quietly throughout the rpm range. When I've had issues with cogging, etc, during the development ...

@geofft because Overvoltage is not set so you get a compile error. I didn't check you settings, that's why I asked for ones matching the CURRENT Java tool :)

I checked in corrected versions
Ahh....ok, my mistake. Thanks for correcting the files.
