I need this specific type because the lip at the end of the female terminal locks into a peg-pergeo battery connector... Peg-perego is a battery connector for a kid's "plastic" 4 wheeler. I don't have the slightest clue where to start looking for connectors besides Amazon and ebay, so any Information would be greatly appreciated.
