Milwaukee M18 Battery Adapter for Power Wheels

Upgrade your child's 12V Power Wheels or DIY ride-on to run on standard Milwaukee M18 18V Lithium-Ion batteries.

Stop buying overpriced, slow-charging replacement toy batteries. This drop-in adapter provides a massive boost in runtime and speed while keeping the vehicle's electrical system completely protected.

Key Features & Built-In Safety Protection:

• 30-Amp Inline Blade Fuse Holder: Protects your expensive Milwaukee batteries and the toy’s motors from over-current spikes, dead shorts, or sudden stalls. (Comes with fuse installed + 1 extra spare).
• Heavy-Duty 12 AWG High-Temp Silicone Wire: Thick gauge wiring handles the high amp draw under load without heating up, melting, or bottlenecking performance.
• Integrated Master On/Off Switch: Easily cut power to the vehicle when parked without having to pop the battery out of the dock every time.
• Pre-Crimped Quick-Connect Terminals: Ready for fast, clean, plug-and-play splicing directly into the factory toy harness or foot pedal switch.
• Secure Slide-Lock Fit: Securely locks your M18 pack in place with the factory spring latch so it won't bounce loose over bumps.
