Checkout the Anderson Power Pole series. the PP45's can handle up to 45A, so they're great for our applications. It's a single connector for each lead, but they interlock together to form larger connectors very easily. They also give you good polarity protection when you lock two or more together, as there's only 1 way to plug them in (like the Anderson connector we use for the battery).
If you decide to go that route, I highly recommend getting a proper crimper for them, like the one available here:
