Many parents who are looking to buy a 24v ride-on for their son or daughter may be wondering if they can use a 24v battery in a 12v ride-on.

It might seem like the obvious answer is yes, but unfortunately, it's not advised.

24-volt batteries typically have twice as many cells as 12-volt batteries, meaning that you will need at least two 12 volt batteries to power your car instead of one 12 volt battery.

This doesn't mean that 24 volts are bad; they just require more space and weight than what most cars can handle.

What is the difference between 12v and 24v batteries?

A 24v battery has twice as many cells as a 12-volt battery, meaning that it usually takes two 12-volt batteries connected in series to achieve a 24-volt system instead of a single 12-volt battery.

This difference in voltage has several important implications:

Battery Capacity and Power Output:

• A 24v system can deliver the same power as a 12v system with half the current, resulting in less heat generation and improved efficiency.
• For example, a 100Ah 12v battery stores 1200Wh of energy (12V x 100Ah), while a 100Ah 24v battery stores 2400Wh (24V x 100Ah).

Battery Life Comparison:

• 24v systems typically have longer battery life due to lower current draw and reduced stress on individual cells.
• A fully charged 24v battery can last approximately 1-1.5 hours of continuous use in ride-on toys, compared to 45-60 minutes for 12v batteries.

Charge Times:

• Initial charge for 24v batteries is usually around 18 hours.
• Regular charging time for 24v batteries is approximately 10-18 hours, depending on the specific battery and charger.

Typical Use Cases:

• 24v systems are often preferred for larger ride-on toys, off-road capabilities, and when more power is needed.
• They are commonly used in applications requiring over 3000W of power or generating over 3000W of solar energy.

Different ride-on toys and vehicles have varying requirements for battery voltage and capacity, so it's crucial to consult the manufacturer's specifications before attempting to use a 24v battery in a 12v system.

Using the wrong voltage can damage the vehicle's electrical components and potentially create safety hazards.

Why would you want to put a 24v battery in a 12V ride-on?

A 24-volt battery is usually much larger and heavier than a 12-volt, so it's not always easy to find 24v batteries that are compatible with the car.

Also, the reason why manufacturers don't install 24-volt batteries in their cars is that they require twice as much space and weight as what most vehicles can handle.

A 24-volt battery is also harder on your child's 12v ride-on and can destroy its motor in some cases if you don't keep an eye on things for signs of wear or damage and also compatibility issues.

How do I install a 24v battery into my 12V ride-on?

Installing a 24V battery into a 12V ride-on requires careful consideration and proper safety measures.

Here are some detailed steps and safety tips:

Safety Precautions:

• Always wear insulated gloves when handling batteries.
• Ensure the ride-on is completely powered off before starting work.
• Never connect the battery in reverse polarity, as this can damage the electronics.
• Use a fuse rated appropriately for the increased current of the 24V system.
• Keep tools and metal objects away from battery terminals to prevent short circuits.

Common Mistakes to Avoid:

• Skipping the fuse installation, which is crucial for preventing electrical fires.
• Using undersized wires that can overheat with the increased current.
• Failing to properly insulate connections, leading to short circuits.
• Not securing the battery properly, which can cause damage during use.

Remember, upgrading to a 24V system will significantly increase the power and speed of the ride-on.

Ensure your child is ready for this increase and always supervise their use of the upgraded toy.

Additionally, this modification may void the manufacturer's warranty and could potentially damage the ride-on's motor or electronics if not done correctly.

For safety reasons, if you're not confident in your electrical skills, it's best to consult a professional or consider purchasing a ride-on designed for 24V operation instead of modifying a 12V model.

Installing a 24V battery into a 12V ride-on requires careful consideration and proper safety measures.

Comparative Performance Analysis

To help you make an informed decision, let's examine the real-world performance differences between 12v and 24v ride-on car systems:

While 24v systems generally outperform 12v systems in most categories, it's important to consider your child's age, experience level, and intended use when making a decision.

For younger children or those new to ride-on cars, a 12v system may provide a more appropriate and manageable experience.

As children grow and become more confident, a 24v system can offer enhanced performance and longevity.

Cost Analysis of Upgrading Batteries

When considering an upgrade from a 12V to a 24V system for your ride-on toy in the UK, it's important to understand the full financial implications.

Here's a breakdown of the costs involved:

Cost-Saving Tips:

1. Look for battery combo deals that include a charger from UK retailers.
2. Consider purchasing a universal charger that works with both 12V and 24V systems for future flexibility.
3. Buy components in bulk if you plan to upgrade multiple ride-on toys.

Long-Term Considerations:

• Increased Durability: 24V systems often last longer, potentially saving money on replacements.
• Higher Resale Value: Upgraded ride-ons may fetch a better price if sold on UK secondhand markets.
• Extended Usability: The higher power allows the toy to be used by older/heavier children, extending its useful life.

While upgrading to a 24V system involves a significant upfront cost, it can provide better performance and potentially longer-lasting enjoyment.

However, it's crucial to weigh these costs against your child's needs and the expected lifespan of the toy. For younger children or those who may outgrow the toy quickly, sticking with the original 12V system might be more cost-effective.

Remember, safety should always be the primary concern. If you're unsure about any aspect of the upgrade process, it's worth investing in professional installation to ensure the modification is done correctly and safely.

Always ensure that any electrical modifications comply with UK safety standards and regulations.

What are some of the benefits of upgrading to a higher voltage system?

- 24v ride on car will go up hills better and be able to use for more than an hour at a time

- 24v cars can have increased range due to the 24-volt battery and are more efficient when charging. Any sort of battery needs to be fully charged before you use them for long periods of time.

- 24 volt systems provide power to the car and accessories without a lot of losses which means 24 volt ride-on cars are more efficient.

- 24v batteries have a much higher power density which means that they can provide the same amount of energy in less physical space.

- 24 volts is many times better than 12 volts because the battery can be made smaller but still able to hold as much charge and power.

Fuses

24 volt systems use a fuse to protect the battery from power surges. The 24-volt system uses a 50 amp fuse, which is only needed if you are using 24v remote controls or oversize motors.

12-volt batteries need 30 amps of continuous amperage for charging and 24 volts need 60 amps of charging voltage on an intermittent basis.

Again, this varies from car to car, so please check your instructions or check with the retailer that sold you the car.

You should check your owner's manual for specific information about which type of battery to use in the car or vehicle, but don't be surprised if you can find 24-volt equivalents for most models.

There are very few 24-volt models on the market because 24-volt batteries are more expensive and 24-volt motors, controllers, radios, and chargers cost significantly more than 12v models.

Gearbox

It is best to buy a new gearbox that is compatible with a 24-volt battery and motor. In fact, most of the components within your ride-on will need to be checked for compatibility.

Motherboard

If you change your 24-volt battery for a 12-volt one, you will also need to replace the motherboard with a 24-volt compatible one.

A 24-volt battery is different from 12 volts in that it has more amperage, which means it can give your child a stronger and faster ride. 

Additionally, because 24-volt batteries are more expensive than 12-volt ones, this type of car or truck is often a more expensive option, so just keep that in mind.

Seat Belts

Now that the car has more power, the seat belts will need to be 24-volt compatible as well.

Additionally, if you are thinking about putting this type of battery into a smaller vehicle like an ATV or dirt bike then it would also make sense for the 24-volt battery to have a higher amperage.

How Do You Hook Up Two 12V Batteries to Make 24 Volts?

Note: We do not recommend this!

Parents can create a 24V ride-on toy vehicle by connecting two 12V batteries end to end in an electrical series.

There are two 12v batteries in this diagram. The positive terminal wire should be hooked to one battery, and the other battery’s negative terminal needs to be hooked up as well.

Best way to charge your new battery 24v battery

24-volt batteries should be charged with a 24-volt charger.

In the process of charging your new 24v battery, you can't just use any 24-volt charger.

24v chargers are designed to charge the battery at a specific voltage and current

Also, 24-volt batteries should be charged with a 24-volt charger.

Common Issues with Battery Upgrades

While upgrading the battery voltage in ride-on toys can provide increased speed and power, it's important to be aware of potential issues that may arise:

Overheating:

• Increased voltage can lead to higher current draw, causing motors and wiring to heat up more quickly.
• Symptoms include reduced performance, burning smells, or automatic shutdowns.
• Solution: Install heat sinks on motors, upgrade wiring, and monitor temperature during use.

Power Surges:

• Higher voltage batteries can cause power surges that may damage electronic components.
• This can lead to erratic behavior or complete failure of control boards and switches.
• Mitigation: Install a fuse between the batteries to protect against sudden current spikes.

Motor Compatibility Issues:

• Stock motors may not be designed to handle the increased power from higher voltage batteries.
• This can result in reduced motor lifespan or premature failure.
• Consider upgrading to higher-rated motors or limiting usage time to prevent damage.

Battery Management System (BMS) Conflicts:

• Some ride-on toys have built-in BMS that may not be compatible with higher voltage setups.
• This can cause incorrect battery level readings or unexpected shutdowns.
• Solution: Some enthusiasts bypass or reprogram the BMS, but this requires advanced skills.

Charging Challenges:

• Standard chargers may not be suitable for higher voltage battery configurations.
• Using incompatible chargers can lead to undercharging, overcharging, or safety hazards.
• Invest in a compatible charger designed for your new battery setup.

Structural Stress:

• Increased speed and power can put more stress on the toy's frame and components.
• This may lead to faster wear and tear or potential safety issues.
• Regularly inspect the ride-on for signs of stress and consider reinforcing key structural points.

By being aware of these potential issues and taking appropriate precautions, you can maximise the benefits of a battery upgrade while minimizing risks.

Always prioritize safety and consult with experts if you're unsure about any aspect of the modification process.

Wrapping Up

When it comes to the safety of our customers, we always recommend you consult a professional. 

There are many variables that can come into play when replacing your battery and if they're not addressed properly or with care, it could be dangerous for everyone in the vicinity.

It’s important to know the difference between 12v and 24v batteries. 

If you don't, then we wouldn't recommend attempting to replace the 12v battery with 24v. 24-volt batteries are for 24-volt ride-ons, and it's important to follow instructions closely if you're not sure about what type of battery your car is using.

It is also important that you have the right fuses and motherboard. 

If your battery voltage is 24 volts, then it will not work in a 12-volt ride-on car, so make sure to get the correct size for what you need!

You can also put two batteries together to create more power which could solve any issues of needing too much power or running out quickly, but as we have repeatedly said, we wouldn't recommend that you do this.

Where possible, seek help from a professional electrician.
