Troubleshooting - Unable to power on the eBike.

The LCD5 display is for 250W and 350W eBike Conversion Kits.

The YL80 display is for 500W, 750W, 1500W, and 2000W eBike conversion kits.

The UKC1 display is for the 3000W eBike conversion kit.

How to turn it on:

1. First, turn on the battery.
2. Then, hold the power button to turn on the LCD display. The power button on the YL80 display is located on the side, under the "-" button.

If it still doesn't turn on:

1. Check all connections between the battery, controller, 1 to 4 cable, and LCD display for any visible damage.
2. Inspect the connections for any snapped pins and reconnect everything.
3. Charge the battery for 8-10 hours. Afterward, turn it on and press the button that shows the battery power to check if the red and green LEDs light up. It’s also recommended to test the voltage with a multimeter. If the LEDs don’t light up or the voltage is abnormal, the battery should be the issue.
