Hello, I am quite new in this hobby and I have decided to upgrade to the new MAXX 1/10, but i don't know if my traxxas EZPEAK charger #2970 supports the 3S 6400mAh #2857X connector. Becouse the charger thats recommended #2971 has a different connector then the #2970. Also the car's ESC has a different connector aswell, the 4S batteries same. Won't there be a problem connecting the different 3S connector to the ESC. (Assuming from site images) Really confused about this thanks.
