Power your MX125 with this plug-and-play adapter designed to run Dewalt-style mount batteries. The adapter utilizes the stock connector for seamless integration, ensuring a hassle-free setup.
⚠️ Important Notes:

The controller and motor may overheat during heavy usage.

Worked perfect!

This adapter worked perfect. Plug and play. Mounts to the original battery strap holes. Does not come with the new bolt hardware. Fits a 5ah 20v Dewalt battery perfectly between the adapter and MX125 frame. Noticeable improvement in speed and power compared to the stock 12v battery. Has a similar top speed in the grass to my daughters stock mx350 now.
