YNDZ 2-in-1 Power Wheel Battery Adapter for Makita 18V | Dual 18V/20V and 36V/40V Output | 14AWG Wire

Overview

Elevate your power wheels, RC cars, robotics, and DIY builds with the YNDZ 2-in-1 Power Wheel Battery Adapter. Designed to convert two Makita 18V lithium packs into flexible power sources, this adapter unlocks dual voltage options to suit a range of projects and environments, helping you explore more ambitious configurations without swapping batteries mid‑work.

Dual Voltage, Flexible Performance

The 2-in-1 design provides two voltage tiers: 18V or 20V as one output pair, and 36V or 40V as the other. This setup lets you balance power and runtime for different devices, from high‑torque RC cars to precision automation in DIY robotics.

Important note not to charge batteries: this unit is intended for power output only and should not be used to charge Makita packs.

Quality Construction and Safety

Built with heavy duty 14 AWG wire and a compact 8 inch (20 cm) lead, the setup is designed for stable, high‑current delivery up to 30 A. Integrated protections guard against over voltage, over current, over charge, and short circuits, and are complemented by 30 A fuses and secure wire terminals for trustworthy connections.

Compatibility and Use Cases

Compatible with a wide range of Makita 18V LXT lithium batteries including BL1815, BL1820, BL1830, BL1840, BL1850, BL1860 and related B-series variants. This makes it suitable for power wheels, ride on trucks, robotics experiments, and other DIY projects that can benefit from enhanced power delivery without frequent battery changes.

What You Get and How to Use

Package includes 1 power wheel adapter and 1 wiring terminal. Battery not included. Warm tip: remove the adapter from the battery when not in use to avoid drainage. This adapter provides power output only and should not be used for charging.
