Things You'll Need
Instructions
Open the battery sled of the Stampede and remove any old batteries that may be present.
Place all four 3.7 volt lithium ion batteries into the 4-AA battery holder.
Place the battery holder into the bottom slot in the battery sled onto one of the positive connections.
The battery holder should have a black wire attached to the end of the casing. Attach this wire inside the coil of the closest negative connection inside the battery sled.
Reattach the battery sled to the Nerf Stampede.
