  <p>I don't think it would really be possible to produce a Power Functions compatible connector for less that the $3 LEGO charges for their cable at a small scale, so that's probably your cheapest option.</p>

Answers.Text: Welcome to Bricks! That looks like a nice way to make a custom battery box. Unfortunately, this doesn't appear to answer the question about how to make connectors for a custom battery box. We're really looking for answers that directly answer questions rather than those that might add to a conversation.

  Yes it would work, and people have done it.
  
  Here's [a YouTube video](https://www.youtube.com/watch?v=Hr8ZOnIzlVE) someone has made on their own custom Power Functions batteries.

  Yes, I have done so. Wanted to motorize the Wall-E set. Initially did so with a AAA lego battery box in his belly, but with the wires and everything, not really enough room.
  
  So I indeed cut up an 8886 extension wire and connected the wires to a clip you can get in any electronics store on which fits a 9V block battery.
  
  When powering an SBrick or IR-receiver, only the outer wires need to be connected to the clip. When connecting immediately to motor or PF switch, only the inner wires need to be connected.
