Got a question I have the super73 Rx and when I turn the battery on the screen on the bike comes on but won’t show any voltage or range I just did a controller swap I’m unsure the connector from battery to old controller shorted and I replaced them and now nothing could the battery be bricked or something need help

Thx for the view

I did but purely by dumb luck! contact super 73 or replace bms and put new controller + lcd on bike are the only options i know of

Do you know what battery cells do Super73 use? Specs?

I think 13s 4p samsung 50E

I just bought the same battery with the same issue. I'm pretty sure that the BMS-controler connetion is made through the central wires of the battery. I compared the voltage out of it when the battery is on : 1.3v for the faulty one, 1.6v/1.7v on the healthy one, with quick voltage changes. So one (simple) lead could be that the controler needs more than 1.5v there to turn on.. What do you think ?

It's some kind of communication, unfortunately I don't have any information on it... Sorry

@@EbikeRepairs I understand :) I'd like to investigate on that and sort of decrypt the electrical signal of that communication. Do you have a recommendation on the method to use? Knowing that I also have at my disposal a working BMS to compare...

I have this same issue also.. I was digging around in forums and someone said that completely draining the battery will ultimately reset the BMS. I just don’t know how to fully drain the battery without a bike to use it on. I wish super 73 sold parts

@@Teejayx4 I read about that reset method, there’s also the « charging 15s through the discharge port » method. Looking at the BMS PCB, I saw a contact pin called « reset ». It’s one of the 4 cables of the on/off button… Meaning that maybe there’s a way to reset « softly » with that button

Hey man probably a long shot but i dont seem to have the fuse under the battery do you know where it is

Sorry if it isn't in there then I guess there isn't one in the battery! Follow the big red wire and if it's there, it'll be attached somewhere...

I think I said in the video - unfortunately I don't have the battery any more so cant check for you, sorry.

From Japan, I have something to ask about Super73sg1battery. Where should I contact? Please tell me the email address etc.

J'ai le même problème, le bouton reste allumé longtemps et la batterie ne donne aucune électricité au vélo. Avez-vous trouvé d'où ça vient ?

Unfortunately I'm not sure how to fix it - the BMS communicates with the bike and you can't get replacements as far as I know
