Item details Materials, dimensions, what is in the box

Building a 302 ford motor is not the intended use for these ABS plastic MOC power functions parts, which help add motorized movement, remote control, and lighting to compatible small-building-block creations. Choose individual motors, battery boxes, controls, wires, or lighting components for custom builds. These parts are recommended for builders ages 14 and up.

Available options include M, L, XL, servo, train, and buggy motors, plus standard and speed-control infrared remote-and-receiver sets. Use the receiver with the matching remote from this range to help avoid frequency incompatibility. Never connect the servo motor directly to a battery box, as this can damage the motor.

Select the component or bundle your build needs before ordering; choose a separate option rather than expecting one complete set. The lithium battery box is rechargeable. AA and AAA battery boxes each require six batteries of the corresponding size, sold separately. Check your selected option carefully so you receive the intended part for your project.

What problem does it solve?

These parts help with the hassle of adding movement, lighting, or remote control to a compatible building-block project, not an everyday kitchen problem. You can choose motors, controls, battery boxes, and extension wires to suit your build instead of buying a complete set when you need a specific component.

For a smoother setup, pair the infrared receiver with its matching remote and check which battery option your project needs. This helps avoid mismatched controls and makes planning your next build more straightforward.

The problem in numbers

  • US teens averaged 8 hours and 39 minutes of daily entertainment screen use, excluding school and homework. (Common Sense Media, nationally representative US survey conducted in 2021, 2022)
  • Entertainment screen use increased 17% among both US tweens and teens between 2019 and 2021. (Common Sense Media, 2022)
  • Only 34% of US teens said they enjoyed using social media a lot, although 84% used it. (Common Sense Media, nationally representative US survey conducted in 2021, 2022)

For families looking for an alternative to screen-based entertainment, these components offer a hands-on building activity for teens who enjoy constructing motorized creations. They add movement, lighting, or remote control to compatible building-block projects, without promising to reduce screen time.

Why choose this one?

The strength here is flexibility: ABS plastic components, several motor types, and both standard and speed-control infrared remote options let you select parts around your building-block project. Remote-control options pair a controller with a receiver, while extension wires come in two lengths for different layouts.

You also have a choice of rechargeable lithium, AA, or AAA battery boxes. That gives you flexibility when planning how to power your creation. Package contents depend on the option you select; the different components are not all included together.

What exactly do you get?

Your package contains the option you order: an M, L, XL, servo, train, or buggy motor; a lithium, AA, or AAA battery box; a standard or speed-control infrared remote with receiver; a control switch; an LED power strip; or an extension wire measuring approximately 9.8 inches (25 cm) or 19.7 inches (50 cm). These are separate purchase options, not one combined kit.

Use the matched remote and receiver together for control. AA and AAA boxes each take six corresponding batteries, not included. The lithium box is rechargeable. Do not wire the servo motor directly to a battery box.

Frequently asked questions

Straight answers about the materials, care and everyday use — no fine print.

What are these parts used for?

These parts add powered functions to compatible small-building-block projects. Available components include motors, infrared controls, battery boxes, extension wires, a switch, and an LED power strip.

Does every component come in one package?

No, you receive the component or bundle you select. The available parts are separate purchase options, not a single complete kit.

Which motor options are available?

The options include M, L, XL, servo, train, and buggy motors. Check the requirements of your building-block project before selecting a motor.

What material are the parts made from?

These building-block components use ABS plastic. Select the component type your project needs, such as a motor, battery box, or control accessory.

Are these parts compatible with LEGO building blocks?

These parts are designed for LEGO-compatible small-building-block projects. Check your build's connection and power requirements before combining electrical components.

What batteries do the AA and AAA boxes require?

The AA battery box requires six AA batteries, and the AAA battery box requires six AAA batteries. Those batteries are not included.

Is the lithium battery box rechargeable?

Yes, the lithium battery box is rechargeable. Select the lithium option if you want a rechargeable box rather than an AA or AAA battery box.

Can I connect the servo motor directly to a battery box?

No, do not connect the servo motor directly to a battery box. A direct connection can burn out the motor.

Can I use an infrared remote I already own?

Use the receiver with the matching remote offered in this range. Other pairings can have incompatible frequencies.

How long are the extension wires?

The extension wire options are approximately 9.8 inches (25 cm) and 19.7 inches (50 cm). Select the length needed for your component layout.

How should I clean these components?

Do not assume these electrical parts are washable or suitable for immersion. Check the care guidance for your specific component before cleaning.

Would these parts make a suitable gift for a young builder?

The recommended age is 14 years and up. For gifting, check which component the recipient needs, because a single motor or battery box is not a complete powered building set.
