Bullet connectors on Battery/ESC

After reading the "are deans enough" topic I desided to solder 5.5mm gold connectors to my ESC and Battery. But what is the best thing to do? (So that the Battery connectors won't come against each other)
The best to me sounds: 2 Female connectors on the battery (with heatshrink ofcourse) and 2 males connectors on the ESC (Again with heatshrink ofcourse). Or is there a better combination? I'm a bit afraid that the + and - of the LiPo will touch eachother...
