    QS138 90H V3 Max Voltage

    It's probably better to make the voltage higher and not use flux weakening, which consumes a lot of current and heats up the controller and motor.

    What 84v controller for qs138 90h engine

    It also has a maximum voltage of 90V and 24s is over 100V when fully charged.

    What 84v controller for qs138 90h engine

    I don't know if he'll manage because the bike's weight will be around 200kg. What do you think?

    What 84v controller for qs138 90h engine

    I see, so choose the 96 for 84v? The most powerful I can afford :-) ?

    What 84v controller for qs138 90h engine

    It is always good to have a little safety margin, and pricewise it is no big difference. This one would be perfect for me :-) Would you like to sell it?

    What 84v controller for qs138 90h engine

    Thanks for the answer. I want to get 30kw of instantaneous power, I think it is possible with this engine. And why do you suggest 96v for a voltage of 84v? Isn't 84v enough?

    What 84v controller for qs138 90h engine

    Hello. I am currently building a Suzuki SV 650 conversion and I am looking for a 24s 84v controller for the QS138 90H engine. In one of my projects I use a Votol EM200 and it is ok but I have not seen a Votol for 84v. I am thinking about a far drive. Regards

    TSDZ2 on 72v

    In what sense? It will be powered by 60v, which means that the 48v battery was fully charged, so it will simply have full power all the time, so it should work the same.

    TSDZ2 on 72v

    Yes, but 90% is still much better than 48v power supply

    Very good job :-) I just bought such a motor and a USB cable for programming. Can you send me the update file?

    TSDZ2 on 72v

    Overall, this converter is a gamechanger because there will be no voltage drop and at 5% of the battery, i.e. close to 3v, there will still be full 60v voltage and full Ampere power. So now I'm glad that I decided on a 20s battery because I also made it using high-current 6p Sanyo NSX cells, so...

    TSDZ2 on 72v

    Many thanks, I bought it a little cheaper on Aliexpress :-) This will be the perfect option because the 22A that the controller draws will be easy work for it. I also bought it instead of TSDZ2, TSDZ8 is a bit more expensive but apparently much better and stronger in terms of paint.

    TSDZ2 on 72v

    Hello, I have an engine in the wheel now, but it doesn't work well off-road because the wheel is too heavy. My battery is 20 seconds old, maybe I could use a converter and lower the voltage. Or maybe tsdz8 will go for 20s? it is definitely more powerful and is said to have a factory output of...

    TSDZ2 on 72v

    Hello, is it possible to convert the TSDZ2 engine to 72v? I have a full bike with this voltage and I would like to put this motor in it because the wheel motor runs very poorly off-road. Regards

    xKillah - Enduro eBike

    Great design. Wouldn't it be more efficient to drive directly from the engine to the rear wheel and bypass the transmission? Is it possible to buy a design for burning from you? I have such a company in my city :-)

    Cineco City Slicker, driver programming

    Hello, I need to reprogram this controller because the handle pulls a lot with it as if it was set to a small voltage range but I don't know which pins and what program to do it, it's a controller from the Cineco City Slicker moped. Regards

    Votol EM-200 Controller

    Currently I have a 1:4 ratio but it is too small, I will put 56, 65 teeth on the rear and it should be great and the maximum speed should be in the range of 130-140.

    Votol EM-200 Controller

    Hello, I have a problem with the slow start of the votol em200 controller with the qs 138 70h engine. The settings are shown in the picture. I was doing hall angle study and it was 55 degrees. The engine runs very well, but from 0 to 40 km / h it accelerates slowly, only then it pulls with full...

    Rewinding the qs 138 70h engine and replacing the magnets

    Yes, of course, but my friend is already taking care of it, so I prefer to roll it on our Polish copper. Possibly magnets, but that's for sure after testing.

    Rewinding the qs 138 70h engine and replacing the magnets

    I didn't buy this engine used, not new :-) also it could have been overheated once and it just burned up at my place.
