While it is difficult to insert #10, I spread the contact a little to help. Using the APP crimper (we got ours from West Mountain Radio) the contact is returned to normal and makes a great connection. As extra insurance, we add a little solder just to be sure.
The Anderson connectors can be stacked into multiple contacts that are also polarized. We have used up to sixteen contacts in one connector bundle in the past.

Read the data sheet I provided the link too. 45A rating is the continuous duty, which for this connector is considered more than 1 minute, only when they are in a single configuration with 10ga wire.
Stack them together and the continuous duty rating drops way down.
I realize many teams "have gotten away with it" however one of the concepts of first is to encourage good, safe design practice. Using a connector rated for ~30A in a circuit that uses a 40A circuit protection device is not good, nor safe design.
