    ENGLISH MODE OFF ! : Merci beaucoup pour ces réponses très claires sur une option que je n'avais pas pensé et aussi pour le schéma ! Et merci de le faire en Français, ça facilite pas mal la compréhension !!! Je referais une synthèse en Anglais de nos échanges pour que tout le monde en profite…...

    Thank you very much for all these precision !

    Uh no, in fact to be honest I have designed with a contactor cause I didn't know BMS could lead some precharged switching between batterye and controller. But then it's true that if BMS draw 5 more watts than contactor, I prefer to invest some more money to have a contactor... Thank you for this...

    Oh OK, that's why some guys talk to me about settings of the BMS but I didn't understand...more clear with what you said ! But still some questions : - so I have the BMS inside my battery casing with a QS10 connector and...ntohing else until controller ? I plug the battrey to my bike and as the...

    Good thank you for your information. I will check with the supplier if this back EMF resistance property of the coil is done with their contactor. And if not, at least I got your reference from VISHAY so I will install thos type of diode on any of my contactor. Thank you very much (y)

    As told above, please find my version of your installation. Feel free to tell me what you think and/or recommand : And....some questions !...sorry.... : - what do you think of the TYCO contactor I intend to use, about the back EMF close to zero on coil side ? Do I need still to install...

    KTM e-SXF 2009 in the French Alps

    OK I understand, it's for back EMF coming from devices with inductance, which can put harsh currents back when turned off. Is that true ? But the contactors I intend to use refer to that description about their coils : Maybe I'm false but I understand that the coil inside this contactor liits...

    Thanks a lot. I have both drawings of your development so it's cool to figure how you have done ! Ok so if I try to understand : - I can avoid the diode by putting a double relay to have a circuit for Vin and a circuit for precharge of controller. What kind of relay do you use ? - there is no...

    Thanks a lot. That's very kind from you. Due to the quality of your jobs, I hope to understand your technology and hope also to implement my build with your solution if you agree.

    Thanks....but unfortunately, I feel no progress...only doubts and misunderstanding !!! :ROFLMAO::ROFLMAO::ROFLMAO::unsure: I'm just looking for something simple, safe and reliable. My battery, some kind of switching device easily operated with no risk and my controller pertfectly setted to run...

    I guess you speak of your scheme below ? : It's quite complicated for me, moreover you're talking about BMS and a relay controlling the circuit. I guess the device of Lee Underwood is more on my acknowlege level !

    KTM e-SXF 2009 in the French Alps

    Yes it's maybe not well drawn, but the left green side of the contactor is the coil under 12V supply of the controller. And that's why the pos26 Vin high voltage of the controller is always supplied when the main switch is turned on to have the possibility ot switch on and off the bike. In fact...

    KTM e-SXF 2009 in the French Alps

    And I have another edition with 12V from controller to supply key switch and controller's coil but not sure if it's OK, mainly about the return back to the "Aux out 12V ground" pos23 of the controlelr ?

    Sorry @j_bjork for the delay since your last post but I have modified and added some precision to my schematic drawing to become more a wiring diagram on AutoCAD. I've been mainly inspired by Kelly controller's documents. I wish this could end up to the final version of my electrical design in...

    3SHUL AS5047P encoder kit installation on QS motor

    Hi everyone ! The question is on the title ! I've tried to find an answer on other topics but never seen something... I would like to install my 3SHUL AS5047P on my QS 138 70H V3 motor, but no information supplied until now from 3SHUL. Is ther anyone who have tried/succeed to this operation ...

    Also, by discussing with Mike Reinalda who got informations from Lee Underwood, I have schematized something like this to eliminate DC converter (it's based on a magnificient paper drawing from Lee ! :ROFLMAO:) : But I was even thinking tu eliminate the momentary switch and have something like...

    KTM e-SXF 2009 in the French Alps

    OK, I know that 12V is supplied by VESC. But if I understand well, if the controller is not supplied through main switch/contactro, no 12V available so no possibility to command the contactor. I'm afraid to not understand in fact. Anyway I'm glad that someone like you who build dream bikes can...

    KTM e-SXF 2009 in the French Alps

    Hello everybody, I'm Greg from French Alps. I come to this forum to present to you my build project based on a dirty KTM 450 SXF from 2009 bought 900€ without motor. The swap consist of : - motor QS138 70H V3 with installation of the 3SHUL encoder kit - ESC 3SHUL CL700 - DOMINO throttle -...
