    Leili controller+ TFT display

    can you provide your contact to Leili? I cant get a hold of anyone there. Their contact info goes to a women who doesnt work there anymore. I just talked to her on the phone and she said the system for the TFT software is unstable because it is so new.

    Leili controller+ TFT display

    Better description. My original display froze and it wouldn't turn off. I tried opening up and looking in side and seeing if there is anything visibly wrong and everything looked okay. So I went home got my spare display for another kit that I was going to set up and that one fired right up...

    Leili controller+ TFT display

    I just rode mine today and the LCD froze. I turned it off by unplugging the battery as the RFID keys wouldnt shut it down. I have a second display and it worked when plugged in. I rode it home and tried the other display that wouldnt turn on previously. Well it started right up.. im not sure...

    Leili controller+ TFT display

    Yes I am experiencing the same exact problem. They literally sent zero setup information with the kit. Mine makes a lot of noise under load and it shakes/slips at a specific range in the rpm.. I am going to contact Leili about this.. Was going to order 200+ units of this kit, but now I am not...

    QS Motor Display 3 Speed Mode Indicator Lights wiring?

    Ok update QS motor didn't design this in house as i suspected. This is why they dont know how to hook this up correctly. So with that said it appears that only the ECO, and Sport (SPT) mode lights will light up.. so if anyone on here has some trick knowledge of how to design a switch that can...

    QS Motor Display 3 Speed Mode Indicator Lights wiring?

    Here is how I have it layed out and it always keeps the "NRM" light on. Also I for ease of wiring i swaped the "eco" an "nrm" lights visually in this example. I am aware that is says ECO first then NRM then SPT..

    QS Motor Display 3 Speed Mode Indicator Lights wiring?

    I purchased a display from QS motor that has 3 indicator lights for the 3 speed modes when selected. QS motor has no actual wiring diagram documents on how the display should be hooked up and supplied only a basic wiring label table. So I discovered that currently the way the 3 speed modes work...

    Ebrake / Regen very weak

    I think this sounds like a challenge that could be fun, but I got the ebrake working well enough.. I realize it is most likely the controller having a predefined setting, because the CAv3 has little effect at 0.0v or greater than 0.1v ... I found that around 0.05v in the ThoOut Ebrake setting it...

    Ebrake / Regen very weak

    So I messed around with the wiring of the ebrake / regen and I finally got it to be stronger, but I think it has a lot to do with the max setting in the controller for ebrake. It is pretty strong now. So I found out that hooked up directly to the controller it is strong now (must of been loose...

    Ebrake / Regen very weak

    Hi I have just finished building an electric moped using a QS v3 motor 4kv, 72v 10ah 50A discharge, EDGE 3000W Sinewave Controller 18 Mosfet, and CAv3 all from LA Ebike. I have the bike up to 40mph so far, but for the life of me I can't get the Ebrake to function with any sort of stopping...

    How does one find out this knowledge? Is there a diagram or something that will help me understand these figures for different battery types or is this just given knowledge for batteries in general?

    72v battery low voltage cut off

    Hi all, I am having trouble finding what is the lowest I should drain my 72v battery to? Right now I have no idea what voltage is too low for a 72v battery.. it charges up to about 82.3v and i hav only taken it down to 71v so far. I want to set the battery cut off on my CA v3 to a safe voltage...

    I am in San Francisco. I sent the photo and QS motor thinks it looks like a short. Still in the process of trying to figure out what happened. it was spinning the first time i started it with loud noises.. it spun up fast and made a louder noise and completely stopped.. after that it never...

    QS v3, 72v battery, & Kinaye 12fet controller cutting out??

    Think I may of found the problem.. the fuse blows now no matter which phase wire configuration I have.. the missing varnish looks to have caused a short? Any way to fix this or is this motor done?
