    LCD S866 + Brainpower controller

    My C&D version of KT36V has front light output, but it just outputs constant battery voltage always. If you have the same, you should buy front light switch and connect it as a switch in the light circuit. If your light is 5-6V you should also include step-down converter in the circuit. I know...

    LCD S866 + Brainpower controller

    The next update.. I've read a couple of articles and watched videos. It seems that my freewheel is broken. It should be released when pedaling and blocked while motor is assisting. And it is being blocked at the beginning of powered rotation but then it slips off. Possibly the curve of current...

    LCD S866 + Brainpower controller

    Also, I've removed cover of the motor. Here is walkassist mode: When motor starts satellite gears stop rotation. Seems like some clutch do that. It is correct behavior. Here is PAS mode: At the moment of strange noice satellite gears start rotation, so it seems that the clutch was released for...

    LCD S866 + Brainpower controller

    It is KT36V 250W, i don't remember exact value, but it seems it is something like 14A. Original Fiido controller is 13A. So battery have to be a good pair for this controller. Any P2 except 0 doesn't show any speed on the display. Possibly this parameter is for motors with build-in speed sensor...

    LCD S866 + Brainpower controller

    P1=87 (checked with real wheel RPM on walk mode - seems to be correct) P2=0 P3=0 P4=0 P5=12 C1=5 C2=0 C3=8 C4=0 C5=10 C6=1 C7=0 C8=0 C9=0 C10=n C11=0 C12=4 C13=0 C14=2 Motor wires are connected color-to-color, contact is good. I tried to play with C5 - limited max current with a half value...

    LCD S866 + Brainpower controller

    No, unfortunately it doesn't work. It works in walk assist mode - drives at 6 km/h even if I am sitting on the bike. But in usual PAS assisting mode it starts to assist, but then at 7-8 km/h it makes an electrical cracking noice and then makes spinup noice and stops producing any torque on the...

    LCD S866 + Brainpower controller

    I made the first ride. It seems that something works wrong. It starts up on PAS, then acccelerates to about 6 kmh and then happens strange sound like strong electric motor startup, in the same moment torque disappears, and then strage sound of increasing rotation speed without any real torque on...

    LCD S866 + Brainpower controller

    I have exactly the same headlight... I didn't know that it can work from 36v. I will make an adapter to connect that light from KT controller connector directly, without a switch. Thanks.

    LCD S866 + Brainpower controller

    Thanks for answers. I don't have spokes, i have aluminium rims, so aftermarket speed sensor is not trivial way for solving the issue. I think I can live without speed.. Regarding headlight - LCD5 manual says that long press of UP button enables headlight. And it really turns backlight on and...

    LCD S866 + Brainpower controller

    Hello. I eventually installed KT36V controller with LCD5 screen on my Fiido D2 bike. It works well but I have a couple of questions. It seems that my motor doesn't have speed sensor - hall connector has only 5 wires while the same connector on the contoller has 6 wires (it seems white wire is...

    LCD S866 + Brainpower controller

    Actually i meant not wiring of every hall sensor, but wiring in hall 5-pin connector. I thought that possibly Fiido uses non standard pinout for some kind of protection against changing controller. But I didn't know that halls "understand" direction. In that case my suggestion doesn't make sense.

    LCD S866 + Brainpower controller

    Halls don't detect direction, just the fact of moving a magnet near. Direction is being calculated by sequental triggering of three hall lines, correct? So, possibly, it is wiring issue too, as for PAS? If you swap two lines of three, possibly it will detect direction correctly.

    LCD S866 + Brainpower controller

    In case of KT I also have to change several connectors to be consistent with Fiido. It not a big deal, but Brainpower seems to be plug&play. About Fiido's PAS - is it usual PAS, the same as KT-V12L from Ali? It has 6 mangets with 2 internal halls, and provides 12 analog signals per round on...

    LCD S866 + Brainpower controller

    Could you advice some beginner-level controller which uses cadence from PAS? It seems that brainpower is the best solution for Fiido - it allows to setup assist reaction and power, and also it is pretty cheap.

    LCD S866 + Brainpower controller

    Which "these" do you mean? As I know brainpower (and kt I think) has the parameter of PAS sensitivity. And it seems that stock Fiido controller has very simple PAS logic, that just counts signals, not speed.

    LCD S866 + Brainpower controller

    Thanks Emanuele, vfr400. Emanuele, do you know whether Fiido stock PAS will work with other controllers (KT for example)? vfr400, it runs about 2 seconds after stop pedaling. Possibly you right, I should try start pedaling fast and slow and compare. Do you know whether KT (or Brainpower)...

    LCD S866 + Brainpower controller

    Hello. I've just bought Fiido D2, and your forum seems to be the most useful of all I saw.. So, Fiido has WK3615MS controller, that is set up very strange. It has pedal assist mode, that turns on after 2 full crank rounds, and it always gives about 50% of power to motor. I tested it today, and...
