Well, nothing against Traxxas connectors (I actually do like 'em pretty well), but the new HOTA D6 Pro charger I got has XT60 ports, and the new battery I got also has XT60 connectors. So for ease of plug-n-play (which I'm a huge fan of) I decided to retire the Traxxas plug on the ESC and give it the XT60 plug as well. In my opinion the XT60s are a little better. Having the round contacts instead of flat gives them more surface area contact which basically means more current can be transferred at any given time. And I do like the shape of the connector as well. A quick glance and you can tell which way to plug it in. The Traxxas ones I was always double checking it was the right way. There is no mistaken the XT60s
