When I say plug converters I mean the discharge plug. It's a 4mm hxt plug to deans female plug. They do not have turnigy packs on hobbyking (with the specs I'm looking for anyway) that has deans plugs. My esc has deans and my charger has deans, so I may as well get a converter instead of soldering a different plug onto it. I'm not very good at soldering, so a converter is nessasary for me. It's only $3 for two of them. Doesn't raise the S&H price.
