Battery Connectors

[Shark413]

I have been running Deans plugs on all my batteries for a while now. But I heard they are only rated for 60 or 70amps and I want to upgrade to something than can handle higher amps. I have some 5.5mm bullet plugs good for 150 amps and some 6.5mm rated for 200 amps. My question is how should I attached them as far as polarization? Females on the battery for both + and - and just be careful when hooking up the batteries, or male on the - and female on the +, or what? Any suggestions or anybody use bullets on there batteries and can share there experiences? I plan on making a non-conducting plug/cover for the ends to protect the connectors/batteries when on in use. Thanks.
