QSDXNYDC Power Wheel Battery Adapter for Makita 18V LXT Batteries with Fuse & Switch, 14 AWG Wire for DIY Toys, Robotics, RC Car & Truck
This QSDXNYDC battery adapter lets you power kids' ride-on toys, RC cars, robotics projects, and other DIY creations using your existing Makita 18V LXT lithium-ion batteries (like BL1850B, BL1860B, BL1830B, BL1840B, BL1820B). It includes a built-in fuse and switch for added safety, plus color-coded 14 AWG wires for easy connection. The adapter itself is not a charger—it simply outputs battery voltage directly from your Makita pack.
Who should use this adapter?
Anyone who already owns Makita 18V LXT batteries and wants to repurpose them for power wheels, RC trucks, robots, or any 18V DC project. It's designed for DIYers, hobbyists, and parents looking to keep their kids entertained without buying dedicated battery systems.
What safety features are included?
The adapter comes with a built-in fuse and a switch. The fuse protects against overcurrent and overheating—if current spikes too high, the fuse blows and cuts power. You get three spare fuses for easy replacement. The switch lets you turn the power on and off manually. Always keep the wires separated when not in use; red is positive, black is negative.
How do you install it?
The adapter has four screw holes for secure mounting to your power wheel or project chassis. Use the included screws (not provided? check) – it's designed for a strong, fixed installation. The 14 AWG wire can handle high-power applications, and the color coding makes wiring straightforward. Note: this is not a charger; remove the battery when storing.
