LCO4818C1H Controller for 48v Model 20'' folding fat bike

I still have yet to receive controller I bought 17 days ago

It appears to be the same controller that was in the bike all the wires matched up but I’m having a problem with the number 30 code. That I believe reports a bad connection. Have not been able to find it yet. Riding bike When motor should be energized I feel good resistance when pedaling. Turn off bike and easier to pedal. Any Suggestions on which wires may be the culprit would sure be helpful

It came quick and not overpriced but I don’t think it should
Have went out in 11 months. I was disappointed that. But it swapped out and worked

Fast shipping--good instructions--switched out controller--had a little trouble squeezing it back in to the compartment but after a few tries all the wires were happy & I'm back on the beach--woohooo!!

Worked as it was supposed to. Easy to swap out if you do a wire at a time. The compartment isn't fully waterproof so I plan on silicone for that. If you go for a second and the motor cuts out this might be what you need
