1. Your ESC is rated for 18 cells but the bec is rated for 10. You need an external regulator (BEC) to regulate all that voltage.
2. To be honest, it doesn't matter. I put the males on the ESC because the Lehner's have females made on to them.
3. Just put some solder in the correct end and tin the wire, then heat them both up and there ya go.
4. Yes, just make a Y connnector. The + from the ESC should go to the + of a Deans, then the - to the - on another Deans. Then connect the 2 connectors with a piece of wire.
