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

The motor is 36V Shengyi Hybrid Brushless DD motor. I don't know why it showed 11amps. Now its back to 1,7amps. I haven't soldered any sensors to the pcb. The controller is S06S from bmsbattery.

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

I've driven with the firmware succesfully and without any firmware related problems now in every four seasons past two years. One thing I'm interested is how could I possibly fine tune my setup so that it would be most efficient and also run as fast as it possibly can. I'm now driving max. 27km/h @6...

No update, technical restriction on how "not set" == 0 is handled in eeprom settings. I see no practical use case where 1km/h is a problem that would justify a complete refactoring.
So I have to use the Java tool and put 0 to the "Without PAS" -section, flash again and I'm set?

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

No, please don't do that. It's clearly stated in the wiki as well. For every additional watt you pull out of the 5V rail the linear voltage regulator inside the controller has to !burn! ~5 watts (depending what kind of resistor the poor chinese guy had at hand botching together your very controller...

Re: 2WD (Two-Wheel Drive) FAQ

Hello. Building a 2wd here also. I have s06s with the rear DD motor and KT36ZWS with the front geared hub motor. Both have individual 36V 15A batteries and they will share throttle, PAS and brake signals and also the common ground of the batteries. I already have mounted the main power switch (of th...

Offroad mode can be activated by the brake lever as known or by a "magic" touch to the smarthphone screen
More info about the "magic" touch please if it's still implemented into the app. Thanks. ;)

Cal b seems to be correct. For a S06S Cotroller cal a has to be something about 100. Ok. Changed the battery cal a value to 100 and now the battery current and target current match very closely.

No, this seems to be a matter of the current cal b value, that is set automatically at startup.

So BluOSEC screen shows; Battery current = 0,2A(46/314) when standstill, and whe...

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

What can I do? It is obvious that you are using a PAS with an internal direction detection. PAS pulses are only generated, when the pedals are turning in the right direction. Just turn your PAS disc on the bottom bracket shaft, so that the arrow on it points to the opposite spin direction. Then it ...

I'm not sure why this is on in the first place, did you uncheck the "clear eeprom" checkbox?
Better explanation of the checkbox function would be needed. This might be obvious but to make things clear, you have to leave it checked or uncheck it when flashing new settings to the controller?

Matters only what current you set.. 25 should be ok as peak. But you can't still hold full throttle.

Even stock fw can be set to half the full curr...
