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

Matters only what current you set.. 25 should be ok as peak. But you can't still hold full throttle. Yes, I totally forgot that the firmware gives the option to lower the current from the controllers max draw, doh. What happens if I full throttle then? Even stock fw can be set to half the full curr...

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

Right, easy.

But I wouldnt push them too much over these 5A..

Install a $1 thermometer on it, temp and voltage drop under load is the only limit.

you can't run 40A.. But more than 15 for sure.

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

"viscous" acceleration. Might be because definition of max current changed: It's now value/cal_a (without cal_b) so if cal_a is 10, 20 Amps would be 200, if cal_a is 5 as on 12 and probably 18 FET controllers, 20 Amps would be 100. Regarding your "requests", why don't you create a pull request if y...

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

OK, I am now officially senile or maybe just retarded. I went back and looked at the listings for the S12S comtrollers I bought from BMSB. These are 36 or 48 volt controllers. There is another model that is 72 volts. The reason my controllers don't like 56 volts and above is because they weren't me...

So, Honya96 you were right. The experiment did not make any difference.

Welding together a 15s 1p fooler pack to try that out. Will be tomorrow before I have results because both it and the main pack will need to be charged.

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

I think no one tested this..

Look at how the gates are parallel, I think it's like 2 paralel for high side and single for low side, so 6+3..

Where you bought this? I like that "design"

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

Yes, that now works (in German legal manner... :( ). There is some fairly severe oscillation or 'pulsing' of the drive though. Is the throttle being scaled by pas cadence - maybe that limiting needs smoothing out? No, the throttle value is used for the target current in the same way as in throttle-...

Thank you. So we can find the settings for a Q128 and for a Bionx IGH3 in the "proven setting" folder of the firmware now. :D
I hope I'll share "proven setting" for 18FET and 48v 1000w hallomotor soon. :D
