    Sounds to me like it is over heating possibly. The metal case is a part of its heat sink. When it shuts down is the speed controller really hot?

    Since this post: The controller failed again.

    It also melted solder and created a solder bridge again. But, this time it was not quite dead yet.
    The Mylar Heat sink Insulator failed. As a result you would hear an spark sound when giving it power for the motors.
    I fixed the solder bridge and could literally see a spark go from the Transistor mounting tab thru the insulation and onto the heat sink.

    If we find a controller I will post here.

    What's wrong with your controller? Any Idea? Could be a very same issue.

    Ours initially failed from riding it hard and with little to no peddle assist thus putting a high demand on the controller components.
    It quits working after a few hour's & i have to turn off the battery & turn back on again constantly, it could be the led display on the handle bar

    Well, I don't believe it. I fixed the solder flows and that bridge. And its powering up my motor.
    Going to check all three phases are working well and replace the connectors.

    I would love a lead on replacement options. Even if he needs a new control head.

  • Replacement Motor Controller Options: X813-AA26E-12Z(500W) 500w 48v

    Good Day,
    My son rode his bike on a flat tire and his motor stopped working. It over heated the controller.

    Looks like the solder melted and flowed a bit.
    Or these were some very poor solder joints to begin with. ;)
    Looks like I have a solder bridge on the B circuit left side. And solder dripped on the left side top.

    I bet my luck is run out and a reflow and a solder bridge fix may not fix this controller. And before I dig into the FETs, I figured I'd try and find a replacement.

    Anyone have a lead on a replacement for a X813-AA26E-12Z(500W) 500w 48v brushless dc motor controller
    It is in an Ancheer 26" model.

    Thanks for your time.
Working...
