The original has a loose sliding battery cover that requires tape or glue. This version has been modified with a snap lock feature (see pictures) that keeps the cover secure.
The wires can be soldered or just wrapped around existing terminals. The bottom part can be mirrored for better cable management. Use solid core wire like used as breadboard jumpers. Use black hotglue if you have it.
