🔌 Battery & Charging Issues

If your battery is not charging or your skateboard won’t turn on, follow these steps to diagnose and fix the issue. Step 1: Ensure Proper Charging Procedure 1. Connect the charger to the battery before plugging into the wall. - Line up the charger pins with the battery pins. - Push the connector straight in - do not insert at an angle. - ⚠️ Do not force the connection or cross the pins, as this can cause damage. 2. Plug the charger into the wall outlet. - The charger light should turn red 🔴 while charging. - The charger light will turn green 🟢 when fully charged. 📷 Step-by-step guide: Charging the Battery Step 2: Troubleshooting Charging Problems Charger Light Won’t Turn On - Try a different power outlet. - Check if the charger cable or battery port is damaged (e.g., pins bent, debris / dirt in the connector, pin melted, etc). Charger Light Stays Green, But the Battery is Dead - Unplug the charger for 30 seconds, then reconnect it. - Ensure the charger is fully inserted into battery before plugging it in. - Try another outlet or test the charger with a different battery (if available). Battery Not Holding Charge or Draining Too Fast - Fully deplete and recharge the battery to recalibrate the indicator. - If the battery continues draining quickly, it may need to be replaced. Battery Won’t Charge or Takes Too Long - Ensure all connections are secure and that the charger light turns red when plugged in. - If the battery is too hot or too cold, let it return to room temperature before charging. - Inspect the charger cable and battery port for visible damage or dirt. Step 3: Battery is Fully Charged but Skateboard Won’t Turn On 1. Check the ESC and battery connection. - Ensure the battery is firmly plugged into the ESC (the skateboard’s main controller). - If the connection is loose, unplug and securely reconnect it. 2. Turn on the ESC properly. - Quickly press the 🔘 ESC power button once and wait 5 seconds. - If the ESC is working, a green LED light will turn on inside the skateboard (📷 see below): 3. Try turning the ESC on manually. - Spin one of the skateboard wheels as fast as possible by hand. - If the ESC is functional, the system should detect motion and power on. 4. Try holding the power button. - Press and hold the power button for 2-3 seconds, then release. - Wait up to 10 seconds for the green LED light to turn on. - Avoid pressing the power button multiple times in quick succession. 5. Try turning the board on with the charger plugged into the ESC (no battery connected). 1. If the board turns on only when plugged in, the issue could be with the battery’s connection to the ESC or the battery / ESC may need to be replaced. Step 4: Still Having Issues? If your skateboard still won’t turn on, contact our support team for further troubleshooting. Next Steps: For battery care, longevity, and safety tips, visit our Battery Safety & Maintenance Guide

🚘 Motor is Jittery / Not Smooth

If your motor feels rough, jerky, or struggles to start smoothly, follow these steps to diagnose and fix the issue. Step 1: Check Motor Wire Connections Loose or improperly connected motor wires can cause uneven power delivery, leading to jerky acceleration or stuttering when starting. 🔌 How to check: - Unplug the motor wire from the ESC, make sure the arrows are lined up (refer to link below for visual), and firmly reconnect it. - Check for bent or damaged pins in the connectors, as this can prevent a solid connection. - Ensure the connectors are fully inserted and not loose. 📷 See how to check motor wire connections: Connecting the Motor Wires Step 2: Check if the Belt is Tightened Correctly If the belt is too loose, it may slip, causing the motor to feel weak or jerky. If it is too tight, it may strain the motor, causing hesitation when accelerating. 🛠 How to check: - Press down on the belt - it should have a small amount of flex but not be overly loose. - If the belt is too tight or too loose, adjust the motor mount position until the belt tension is correct. 📷 Step-by-step guide: Tensioning the Belt Step 3: Tune the Motor for Smooth Acceleration If the motor was not tuned during assembly, it may not be optimized for smooth power delivery. Running the motor tuning process in the ESC settings will help fix jittery movement. How to Tune Your Motor for a Smooth Ride 📷 Watch the full tuning tutorial here: Tune Your Electric Skateboard To ensure your ESC is properly controlling the motor, follow these steps: 1. Find your ESC's unique ID - Locate your ESC and look for a small laser engraving that starts with LT-XXXXX (4 or 5 unique letters / numbers). - Write these letters / numbers down or take a picture for reference. 2. Connect to the ESC using VESC Tool - Open Google Chrome on a computer (Chrome is the only supported browser). - Go to VSC.lectec.com and enter the 5-digit unique ESC code. - Click Connect, then Pair the detected device. - If nothing appears, click Cancel and then select Connect All, looking for the device starting with LT-XXXXX. 3. Run Motor Detection (FOC Mode) - Once connected, navigate to the FOC tab (this controls motor settings). - Click "RL" and then "Measure", which will spin the motor slightly. Make sure the skateboard is on its back to prevent movement when the motor spins. - Click "Apply". 4. Set Hall Sensor Values - Go to the Hall Sensor tab and click the Play button. - The motor will make a high-pitched sound - this is normal. - The system will generate a Hall Sensor table. Click Apply to save these settings. 5. Save the Updated Motor Configurations - Click the "M" button with a down arrow to save all changes to the ESC. - You should see "Motor Config Updated" appear at the bottom.

📲 Motor Tune Didn’t Work

If your motor tuning process failed or didn’t improve performance, follow these steps to resolve the issue. Step 1: Check Motor Wire Connections If the motor cable is not fully plugged in, tuning will not work properly. 🔌 How to check: - Unplug the motor wire from the ESC, make sure the arrows on the connectors are lined up (refer to the link below for a visual), and firmly reconnect it. - Check for bent or damaged pins in the connectors, as this can prevent a solid connection. - Ensure the connectors are fully inserted and not loose. 📷 See how to check motor wire connections: Connecting the Motor Wires Step 2: Check for a Hall Sensor Tuning Failure If you saw the red error alert at the bottom right of the screen during motor tuning that says: 🚨 "Bad FOC Hall Detection" This means that the ESC could not properly detect the motor’s hall sensors, which are responsible for smooth startup and acceleration. You can fix this by completing Step #1 and retry the tuning process. Step 3: Make Sure You Saved the Motor Configuration If you did not complete the last step of the tuning process, no changes were uploaded to the ESC, making the entire tuning ineffective. ✅ Final step to save settings: - After running motor detection, go to the Hall Sensor tab and complete the final detection step. - Click the “M” button with a down arrow to save all changes to the ESC. - A message will appear at the bottom saying “Motor Config Updated”—this confirms that the new motor settings have been applied. If you skipped this step, go back and run the tuning process again, making sure to save your settings before disconnecting. 📷 Watch the full tuning tutorial here: Tune Your Electric Skateboard
