Can You Put a 24V Battery in a 12V Ride-On? What Parents Need to Know

Shopping for a 24V ride-on and wondering if a 24V battery will juice up your 12V model? Can You Put a 24V Battery in a 12V Ride-On? It might sound like a quick power boost, but it’s not that simple—and it’s usually not safe. Let’s break it down.

12V vs. 24V: What’s the Difference?

A 24V battery has twice the cells of a 12V—think two 12V batteries stacked together. Here’s how they stack up:

12V vs 24V Battery Comparison

Two 12V batteries in series

Key Differences

  • Power: 24V doubles capacity (e.g., 100Ah 24V = 2400Wh vs. 1200Wh for 12V).
  • Runtime: 24V lasts 1-1.5 hours; 12V runs 45-60 minutes.
  • Charge Time: 24V takes 10-18 hours; 12V needs 8-12.
  • Use: 24V suits bigger, off-road ride-ons; 12V fits smaller toys.
Warning: Swapping a 24V battery into a 12V ride-on can fry the motor or wiring—check the manual first!

Why Upgrade to 24V?

Parents eye 24V for:

  • More Power: Faster speeds (4-8 mph vs. 3-5 mph) and better hill climbs.
  • Longer Play: Up to 3 hours vs. 1-2 for 12V.
  • Efficiency: Less heat, more juice for accessories.

But here’s the snag: 12V ride-ons aren’t built for 24V’s extra oomph—think bigger size, weight, and strain.

Can You Do It? Risks and Reality

Technically, yes—but we don’t recommend it. A 24V battery in a 12V ride-on can:

  • Overload the motor, burning it out.
  • Melt wiring or the motherboard.
  • Void warranties and create safety hazards.

Most 12V toys can’t handle the space or stress of 24V. Check out this comparison:

Feature 12V Ride-On 24V Ride-On
Speed 3-5 mph 4-8 mph
Runtime 1-2 hours 1.5-3 hours
Terrain Flat surfaces Rougher ground

How to Upgrade (If You Dare)

Still tempted? Here’s what’s needed—but proceed with caution:

Tools Needed
Insulated screwdriver, wire strippers, multimeter, electrical tape, fuse holder
Steps
1. Remove the 12V battery.
2. Check wiring for wear.
3. Connect 24V battery with a fuse on the positive terminal.
4. Insulate all connections.

Safety Musts: Use gloves, add a 50-amp fuse, and never reverse polarity. But honestly? Get a pro—motors, gearboxes, and motherboards often need 24V upgrades too.

Costs to Consider

Upgrading isn’t cheap:

Item 12V Cost 24V Cost
Battery £25-£40 £70-£100
Charger £15-£25 £20-£40
Extras (fuse, wiring) £24-£48

Total DIY: £100-£200. Pro install? Add £40-£80. Worth it? Maybe—if your kid needs the power and you’re okay with the risk.

Wrap-Up

Swapping a 24V battery into a 12V ride-on isn’t a plug-and-play fix—it’s a gamble. For safety and peace of mind, stick to the right voltage or call a pro. Rather skip the hassle? Check out our 24V ride-ons built for the job!

Frequently Asked Questions

Can I use a 24V battery in my 12V ride-on?

Not safely—it can overload the motor and wiring. Stick to 12V unless you upgrade everything.

How do I make a 24V system with 12V batteries?

Connect two 12V batteries in series—positive to negative—but we don’t recommend it without pro help. See the diagram: connecting ride on car batteries

What’s better—12V or 24V for my kid?

12V is gentler for young kids; 24V packs more speed and runtime for older ones. Match it to their age and skill.
