I dont have anything against those types of connectors but WF is right that one is ridiculous with all the wires coming off of it. If thats the route you want to go Id just find one that has like 6-8 connectors on it. Half the connectors on that adpater youd probably never even use.
Either way you go though. just be aware of the fact that if you have connectors with exposed ends on them, make sure they dont short out on anything. For example if you're charging a battery with an EC5 connector then all of the other connectors are getting power to them also so connectors like Traxxas, Deans, Glow ignitor, etc have exposed ends and if they touch anything metal they will short out doing who knows what to your lipo and charger.
