Would 6mm bullets fit on the soldering posts
 

I was thinking that maybe a 6mm bullet would fit on the end of the soldering posts, that way I would have a quick disconnect. Someone let me know, thanks.

You could solder the wire on to the posts and solder a connector to the wire instead of the post themselves. Do the same to the motors and you're set.

If you do anything like this make VERY sure that everthing is shrinked wrapped and well insulated. Also make sure to polarize the connectors in some fashion so you can't hook them up wrong. You MUST hook up a to a , b to b, and c to c for the system to work properly.

And DO NOT hook it up backwards on the battery!
