Another Multirotor Question

    Hi,
    I have a 30A 2-4S ESC connected to a Multistar motor. The receiver is also connected to the ESC. When I connect the ESC to a 4S battery, I'm getting sparks coming out like the wires are shorted. I measured the voltage on the battery at 15.5V and my multimeter can't read the current. Any ideas of what could be causing the short? I would imagine the ESC can handle the battery, any help would be appreciated, thanks.

    Well I'm trying to figure out which direction each of the motors is running so the ESC is connected to the motor. I'm getting sparks at the battery connection when I put the ESC power lines in.

    Has the battery a good connection or are they just push fit temporarily?

    Temporarily, I just put the power wires into the battery connector and immediately get the spark.

    I would solder on proper connectors

    To change direction swop on of the 3 motor wires around

    Just pushing wires in is not ideal and not good for component's
