Connectors
Power connectors come in various of shapes and sizes. Choosing a power connector is dictated by power requirements and compatibility. The most common power connectors are XT-60, Deans Ultra Plugs and EC3 and EC5 Bullet Connectors.
I use the Deans Ultra connectors but I found they can lose contact when fully plugged in. This is an inherent design flaw with the T type connector. I would choose the XT-60 connector if I was not so invested in the Deans connector. I favor the XT-60 because they are easier to solder and connect and disconnect with ease.
