ZK2400DH Control Module for the Razor Power Core E100 - Replacement Speed Motor Controller for Electric Scooter, Connectors for Battery, Charger, Brake, Motor, 4-Wire Throttle, Switch, Circuit Breaker

After an initial poor review due to the scooter malfunctioning after a minute, I discovered one of the batteries was defective and intermittently cutting out. The controller worked as expected, although I probably bibn't need it in the first place.

Please understand, I could have done something wrong I just don't know. What I would suggest if you don't understand basic circuitry, (I thought I did), take this somewhere and let the pros do it. It can be tricky.

Not sure if this was the problem but the end result was it all worked
