Looking for ideas to make wire connectors compatible with Lego Functions I like to make custom battery packs for Lego Power Functions. Is there any simple way to make wire connectors?

The only option that comes to my mind is to buy LEGO Power Functions Extension Wire # 8886, cut the wire, and connect it to my custom battery pack. Would that work? Is there a better idea?

Yes it would work, and people have done it.

Here's a YouTube video someone has made on their own custom Power Functions batteries.

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.
