And put the female plugs on the pack, so there's not much chance of them touching and shorting the battery, like they would if you put the male plugs on the pack.

Yeah, you don't want the males to have a sword fight and kill the battery, so be smart and be a pussy..... use the female connectors on battery, as ANY power source should use female types.
