If you've got a 24V kids 4 wheeler and feel like it's time for a little more oomph, upgrading to 36V might be precisely what you're looking for. Moving to 36V can provide that extra kick in speed and power, which many kids find thrilling once they're more comfortable handling the vehicle.
However, it's important to remember that this Upgrade isn't just about fun. It involves specific modifications and new parts that come with unique safety considerations. Therefore, before diving in, let's take a moment to understand the essentials of this project to see if it's the right fit for you and your family.
Understanding the Basics: Voltage, Batteries, and Controllers
Upgrading from 24V to 36V is about giving the motor a boost in power. In simple terms, this increase translates to higher speeds and, depending on the motor, more torque, which can improve overall performance.
When discussing battery types, you have a few options. Some people stick with traditional sealed lead-acid (SLA) batteries, which are expected, while others prefer lithium-ion (Li-ion) batteries. Li-ion batteries are lighter and have a longer lifespan, making them popular.
Alongside the battery upgrade, a new motor controller is essential to smoothly manage the increased power. The controller acts as the system's brain, balancing power flow and ensuring the motor operates safely under the new voltage level. The suitable controller ensures your 4-wheeler doesn't overheat or short-circuit, keeping the ride smooth and safe.
Preparing for the Upgrade
Upgrading your 4-wheeler isn’t as complicated as it sounds, but getting organized will make it a lot smoother.
-
Gather Your Parts: Here’s what you’ll need:
- An additional 12V battery (or replace the old 24V setup with a fresh 36V pack)
- Wiring connectors or jumper wires to link everything up
- A circuit breaker to prevent overload, generally a 30-amp one works well
- Tools like a screwdriver, electrical tape, and, if possible, a multimeter for safety checks.
-
Safety Gear: Since you’re working with electricity, gloves and goggles are a good idea, even if it’s just a small project.
A well-organized workspace makes the job easier and safer, keeping everything accessible while reducing distractions.
Step-by-Step Guide to Converting a 24V 4-Wheeler to 36V
Let’s get into the specifics of transforming your 24V 4-wheeler into a 36V powerhouse.
This upgrade involves a few key steps, from adding an extra battery to adjusting wiring and testing the setup.
Each part of this process is crucial for both functionality and safety, so take your time and follow each step carefully. Here’s how to make it happen:
Step 1: Adding the Extra Battery for 36V Power
The first step in upgrading from 24V to 36V is adding a 12V battery to your setup. Start by disconnecting the original 24V battery to avoid accidental shorts while you work. With a clear workspace, position the additional 12V battery alongside the existing battery setup.
It's essential to connect these batteries in series. This means linking one battery's positive terminal to the next's negative terminal. This type of connection allows the batteries to work together, providing 36V output.
After connecting, double-check that each connection is secure and insulated to prevent sparks or shorts.
Step 2: Upgrading the Motor Controller
With the battery upgraded, you'll need a controller capable of handling the 36V voltage. The motor controller regulates the power flow, allowing for smoother acceleration and preventing overload.
Locate the existing controller, usually near the motor or under a panel. Carefully remove it, noting where each wire connects. Then, replace it with a 36V-compatible controller. This controller will likely have similar wiring but is better suited to the higher voltage.
Secure the wires to the new controller in the same order as the previous setup, ensuring each one is tightly fastened. This step is crucial, as an incompatible controller can cause overheating and damage the motor.

Step 3: Securing the Circuit Breaker and Wiring
Protecting your 4-wheeler's electrical system is essential; this is where a circuit breaker comes into play. A 30-amp circuit breaker is commonly used to protect against power surges and accidental short circuits, which could damage critical components.
Install the circuit breaker between the battery and the motor controller. Start by connecting the positive wire from the battery to one side of the breaker. Then, complete the wiring to the controller, maintaining the positive path and avoiding reverse polarity.
After everything is connected, double-check that each wire is secure and insulated to prevent exposure, which can cause sparks.
Step 4: Testing the Setup
Before hitting the road, perform a "dry run" test to ensure everything functions properly. Lift the vehicle slightly so the wheels can turn freely without moving forward. Power on the 4-wheeler and listen for any unusual sounds from the motor or controller, which could indicate loose wiring or component strain.
Gradually increase the throttle, watching the wheels for steady and smooth acceleration. Stop and inspect the setup if you notice any issues or signs of overheating in the wiring or batteries. Once everything seems to be working well, you're ready to take it for a real-world test!
Step 5: Real-World Testing and Adjustments
Now that the setup has passed initial testing, it's time to let your child take it for a low-speed trial on a flat, open surface. Please encourage them to start slowly and ease into the power difference.
As they drive, monitor the 4-wheeler's performance. Check for any signs of overheating in the controller or battery area, and feel free to make adjustments as needed to ensure everything remains secure and runs smoothly.
Optional Enhancements
Once the Upgrade succeeds, you might consider a few optional enhancements for improved performance.
One option is a motor upgrade designed to handle 36V more efficiently, giving the 4-wheeler even more speed and torque. This is worth considering if your child is comfortable with the upgraded power level and you're looking for a little extra excitement.
Adding throttle controls like a thumb throttle can give your child more control over speed, making the ride more customizable. Installing a battery monitor is also helpful; a small voltage meter will track the charge level so you know when to recharge.
Troubleshooting Common Issues
Even with careful setup, issues can sometimes pop up. Here are a few common troubleshooting tips:
If the motor is overheating, take a break and let it cool down. This can happen more frequently with motors designed for something other than 36V power. For rapid battery drain, check connections and consider upgrading to a higher-capacity battery if needed.
If the motor or controller experiences a sudden power loss, double-check the wiring to ensure all connections to the controller are firm and secure.
Safety and Maintenance Tips
With a newly upgraded 4-wheeler, safety and maintenance routines become even more critical. Make it a habit to inspect connections and wiring before each ride, watching for any loose wires or signs of wear that might need tightening or securing.
Supervise playtime closely. An open area free of obstacles will allow your child to get used to the extra power more safely.
Follow recommended charging practices for your battery type to help prolong its life and ensure safe operation.
Final Thoughts
Upgrading your child's 4-wheeler to 36V can be rewarding, giving the vehicle a new level of speed and power that provides an exciting experience.
However, keeping an eye on performance and watching for signs of wear is essential. Regular checks and adjustments can keep everything running smoothly, while supervision helps ensure safe usage.
This project may not be for every parent, but if you enjoy DIY and want to give your child a new adventure, this Upgrade could be an ideal way to do it. With a focus on safety, you can create a thrilling yet secure ride that both of you can enjoy!
