With this component, you can install a more commonly used metal XP cartridge into the Senbo Long Guardian toy while also supporting rear cable routing. By replacing the original small battery with a high‑capacity cartridge battery, you can enjoy enhanced performance and convenience.

To install this component, you’ll need to provide your own pair of large flat‑head hex socket locking screws—specifically, screws with an M4 thread pitch, a 5 mm outer diameter for the nut, and a 25 mm shank length. Additionally, prepare one M5 threaded rivet nut (typically included when you purchase a metal XP cartridge).
