• Real-time LED Display: Accurately shows remaining battery power and voltage.
• Durable Construction: Made from high-quality Aluminium Alloy and Rubber.
• Integrated Key Switch: For secure power control.

4. Setup and Installation

Installation should be performed by an individual with basic electrical knowledge. Ensure the vehicle's power is completely off before beginning.

1. Prepare the Handlebar: Remove existing grips and clean the handlebar surface.
2. Install Left Grip: Slide the non-throttle grip onto the left side of the handlebar. Secure if necessary.
3. Install Throttle Grip: Slide the throttle grip onto the right side of the handlebar. Ensure it rotates smoothly without binding.
4. Wiring Connection:
   • Identify the corresponding wires on your electric vehicle's controller.
   • Connect the throttle's wiring harness (refer to Figure 3.2) to the vehicle's wiring. Common connections include:
     • Red wire: Positive power supply (typically +5V or +12V)
     • Black wire: Ground
     • Green wire: Signal output
     • Other wires (if present): May be for key switch, speed modes, or battery display. Consult your vehicle's wiring diagram if unsure.
   • Ensure all connections are secure and insulated to prevent short circuits.
5. Test Functionality: After wiring, turn on the vehicle's power. Insert the key into the throttle and turn it to the ON position. Check the LED display for voltage reading and test the throttle's response.
6. Secure Components: Ensure all grips are firmly in place and wiring is neatly routed and secured to prevent interference with steering or braking.

5. Operating Instructions

Using your Haofy Electric Scooter Throttle Grip is straightforward:

1. Power On: Insert the key into the throttle's key slot and turn it to the 'ON' position. The LED display will illuminate, showing the current battery voltage.
2. Voltage Reading Interpretation:

   The LED display shows the real-time voltage. This allows you to accurately determine the remaining battery charge and assess the health of your lithium battery. For example, a fully charged 48V battery might read around 54.6V, while a depleted one might be around 42V. Refer to your vehicle's battery specifications for precise voltage ranges.

3. Throttle Control: Gently twist the throttle grip towards you to accelerate. Release the grip to decelerate. The throttle provides smooth and responsive control over your vehicle's speed.
4. Power Off: To turn off the vehicle, turn the key in the throttle to the 'OFF' position and remove it.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your throttle grip:

• Cleaning: Wipe the throttle grip and display screen with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Inspection: Periodically check the wiring for any signs of wear, fraying, or loose connections. Ensure the grip rotates smoothly without sticking.
• Storage: If the vehicle is stored for an extended period, ensure the throttle is in the 'OFF' position and the key is removed. Store in a dry, cool place.
