I want to throw in the presence of possibly counterfeit connectors as well. If not counterfeit then at least lower quality. I fly RC and use many PP connections for batteries and motor controllers. In the past I purchased a pack of PP connectors from ebay thinking I got a deal. They looked ok but didn't crimp or hold up the same. I ended up dumping them and ordering replacements from powerwerx. Just sharing my experience.

Dave, that is really the key question and very difficult to answer. For starters the crimper should have compound leverage and a ratchet that prevents you from releasing pressure before the crimp is complete. In addition to that the crimper should have removable dies so that it can be used for multiple crimp connectors. The real catcher is that the die used should be the correct die for the crimp connector itself. The connector itself should also match the wire size used. Sorry that was not a complete answer :) If the crimper does not have compound leverage handles and replaceable dies I would avoid it unless it was purchased for one specific use.
