    building the BESC - 100V, 400A motor controller [NOT RECOMMENDED]

    Very interesting project! Would this board be able to handle a 24S lipo battery (100.8V fully charged) or would it go poof?

    a VESC controller for 22S ?

    Would a solution be so simple as to replace some of the DC/DC stage parts for something rated to 120V? or am i just talking nonssense now?

    a VESC controller for 22S ?

    Wow, i totally messup up there :lol: i guess i was more tired than i thought when i posted it. But yeah i have a 24S pack , so i guess i would need a 24S VESC. The fardriver 96 is on my shortlist for the moment. My SeVCON is a pretty solid controller but programming it is a nightmare.

    QSmotor 8kw, how big battery needed?

    i would be very surprised if you get a 100 miles from it. for comparission. the Silence S01 motorscooter has a 7kw hub motor and a 5kwh battery. its range is about 100km or about 62 miles.

    a VESC controller for 22S ?

    yeah i thought of that but i guess it would depend on the quality of the used parts? my 73V Sevcon gen 4 controller has no issues whatsoever with running on 100 volts. it doenst even get warm.

    a VESC controller for 22S ?

    I didnt really plan on 24S my 20S battery pack died, and i could get my hands on some samsung SDI power pack modules. They come in 12S so i put two of them in series. I already had a bms that could handle 24S I could convert back to 72V but that would mean i have to open one of the packs...

    a VESC controller for 22S ?

    Hi all, I searching a controller to replace the current one in my e-scooter. I like the thought behind the VESC and the software seems pretty good from what i have seen. The thing is i have seen one for 20S and it has a max rating of 100V. This seems to be an absolute maximum ( limited by...

    Help for Sevcon Controller troubleshooting Sin Cos warning, sensor issue

    you say that after you switch it off and then back on , the problem returns? Do you have access to DVT software so you can check if the settings in the controller have changed? ( seems unlikely to me) an oscilloscope to see the encoder signal might be a very usefull tool. regards, sander

    changing sevcon behaviour

    How did you setup the Regen on your govecs? I have been trying for a while on my 3.4 but i cant get it to work? I have set neutral braking and regen current but nothing happens. If possible i would like to hook it up to be activated when pressing the rear brake .

    TWIZY MOTOR & SEVCON

    from what i know about twizzy's, most things are controlled via can. even replacing the battery is not a straight forward job. There is an opensource project based on an arduino that helps with the CAN part of things to get a new battery running. also, if you visit the faqmous video site and...

    Undervolting.. how much topspeed would i loose?

    Mostly because a set of new 18s lg chem batterys was offered to me. I like the idea of having 18 pouches vs 440 18650 cells that are in my battery now. Spotwelding 400 plus cells is a pita 😂 Also for some reason i have in my head that lg puched would outlast any 18650 battery. But im not...
