    Pop, Oh dear :(. Most certainly a can (capacitor) has blown, usually identified at the time by a cordite type smell. It may be possible to solder a new can if you know the spec of it if its the only damage other wise a new controller.
    There will be fibre everywhere when you open the controller and the remains of the overheated can, possibly with 2 legs still soldered.

    The main capacitor across the battery input will be blown, and you might find that the shunt is blown too. You can try changing the cap and/or repairing the shunt, but the probability is that there'll be other damage, so you might be forced to take the opportunity to get a better controller.

    Controllers are cheap so, unless you are keen to fix because you have time and are keen to learn.....i wouldn't bother !! Just get a new one

    If it's a 250w brushless system them your options are plentiful and price pretty much come .down to how long you are prepared to wait for delivery
