the orion power plugs are probably the easiet, then the deans but when you do the deans use the male one on your esc and charger and the females on yout batteries. one cause you can a pack of deans that comes with one male and 4 female connectors. also you can buy just female connectors, you can't buy males by themselves. also when your batter packs are stored away it wont matter if the female connectors make contact since no metal is exposed they wont short out. and when your soldering them have them plug in as a set so that they stay straight if you over heat it with your iron. you can get them hot enough the plastic melts a bit then the prongs move and you cant them plugged in. such as do all your battery packs first with a male that is not wired yet, then have an extra female connector to the solder the male one to your esc and charger.
