How To Convert Power Wheels To 20v Dewalt

Transforming a Power Wheels ride-on toy into a 20v DeWalt-powered machine isn't just a fun project; it's a practical upgrade that can significantly extend playtime and tackle tougher terrains. This conversion involves replacing the original, often underpowered, battery system with a robust DeWalt 20v battery, providing increased speed, power, and run time. This guide provides a step-by-step approach to performing this modification.

Preparation and Safety

Before starting, gather all necessary materials and tools. You'll need:

• A Power Wheels vehicle
• A DeWalt 20v battery and charger
• A DeWalt battery adapter (designed for Power Wheels)
• A fuse and fuse holder (30-40 amp recommended)
• Wiring (12-14 gauge automotive wire)
• Wire connectors (crimp connectors or solder and heat shrink)
• Wire stripper/crimper
• Screwdrivers (Phillips and flathead)
• Pliers
• Drill (optional, for mounting the adapter)
• Multimeter (for testing voltage and polarity)
• Safety glasses
• Work gloves

Safety First: Always disconnect the original Power Wheels battery before starting any modifications. Wear safety glasses and work gloves to protect yourself. Work in a well-ventilated area.

Step-by-Step Conversion Process

1. Disassemble the Power Wheels

Carefully disassemble the Power Wheels to access the existing battery compartment and wiring. This usually involves removing screws and plastic panels. Take photos as you disassemble to help with reassembly later.

2. Remove the Original Battery and Wiring

Remove the original battery and any associated wiring harness. Cut the wires connected to the motor. Leave enough wire length on the motor side for future connections. Dispose of the old battery properly according to local regulations.

3. Install the DeWalt Battery Adapter

Mount the DeWalt battery adapter in a convenient location within the battery compartment. Some adapters come with mounting holes; use these to secure the adapter to the Power Wheels frame using screws. If necessary, drill pilot holes for the screws.

4. Wire the Fuse Holder

The fuse is a critical safety component that protects the circuit from overloads. Connect the fuse holder in-line with the positive (+) wire coming from the DeWalt battery adapter. Cut the positive wire and connect the two ends to the fuse holder terminals. Ensure the fuse holder is easily accessible for future replacement.

5. Connect the Wiring

Connect the DeWalt battery adapter's wiring to the Power Wheels motors. Identify the positive (+) and negative (-) wires on both the adapter and the motor wires.

1. Use wire connectors (crimp connectors or solder and heat shrink) to connect the positive wire from the adapter (after the fuse) to the positive wire of the motor.
2. Connect the negative wire from the adapter to the negative wire of the motor.
3. Ensure all connections are secure and insulated to prevent short circuits.

Polarity Matters: Double-check the polarity of all connections. Reversing the polarity can damage the motor or other components.

6. Test the Wiring

Before reassembling the Power Wheels, test the wiring with a multimeter. With the DeWalt battery connected to the adapter, use the multimeter to measure the voltage at the motor terminals. Verify that the voltage is approximately 20v and that the polarity is correct. Also, briefly test the motor by applying power and ensuring it runs in the correct direction. If the motor runs backward, reverse the polarity of the motor wires.

7. Reassemble the Power Wheels

Carefully reassemble the Power Wheels, following the photos or notes you took during disassembly. Ensure all wires are properly routed and secured to prevent them from being pinched or damaged. Replace all screws and panels.

8. Final Testing

Once the Power Wheels is fully reassembled, perform a final test. Connect the DeWalt battery and operate the vehicle in a safe area. Check for proper speed, acceleration, and braking. Monitor the wiring and battery adapter for any signs of overheating or malfunction.

Practical Tips for Daily Use

• Battery Management: Use multiple DeWalt batteries to extend playtime. Keep batteries charged and stored properly when not in use.
• Terrain Considerations: The 20v DeWalt battery provides increased power, allowing the Power Wheels to tackle tougher terrains such as grass, gravel, and inclines. However, avoid overloading the vehicle or operating it in excessively challenging conditions.
• Maintenance: Regularly inspect the wiring, connectors, and battery adapter for any signs of wear or damage. Replace any damaged components promptly. Check the fuse regularly and replace it if it blows.
• Speed Control: The increased power can significantly increase the speed of the Power Wheels. Supervise children closely and consider installing a speed control device to limit the maximum speed if necessary.
• Upgrades: Consider upgrading the Power Wheels tires to improve traction on various surfaces. Heavier-duty tires can provide better grip and durability.

Troubleshooting

• No Power: Check the battery connection, fuse, and wiring. Ensure the DeWalt battery is fully charged and properly seated in the adapter. Use a multimeter to trace the voltage and identify any breaks in the circuit.
• Motor Runs Slowly: Check the battery voltage and wiring connections. Ensure the motor is not obstructed or overloaded. Consider upgrading the motor if necessary.
• Fuse Blows: Replace the fuse with the same amperage rating. If the fuse continues to blow, there may be a short circuit in the wiring or an overload on the motor. Inspect the wiring for any damage or exposed wires.
