KKmoon 36V-48V 350W Brushless motor controller, Electric Bicycle E-bike Scooter Speed Controller,DC Brushless Motor Regulator Speed Controller

Controller burned out within two days upon inspection it was discovered that during manufacture the control circuit board (which is through hole soldered) had not been properly secured/insulated against contact with the surrounding aluminium case. The bottom of the circuit board contacted and shorted against the case, burning several traces off. Word to the wise: open the case and inspect the unit inside recommend insulating bottom of circuit board before installing motor controller

plugged in the controller for a electric 36v scooter... nothing came on or worked. I used my multimeter to test voltage... most of the lower voltage wires were not getting power. I then took apart the controller to find out the the board has been burnt up already. not good sales practice to send out used and broken parts. looks like mosfet are burnt up

STOP—FIRST THING!!! CUT A PIECE OF CARDBOARD and open up the case and slide it into the bottom and close it back up!! WHY? Because The Negative and Positive points are sooo close on the circuit board that the Case enables the power to jump across and spark! After I put in the Cardboard it works like a champ—perfect! No more sparking!

Hard to find instructions hard to read wiring diagrams when you do find him labeled in Japanese pretty much junk don't waste your money

It’s hard to figure out which wires are what cause the plugins are all in Chinese
