I know this could go into the LiPo forums but this pertains only to the Rally, so does the 3S by Traxxas have about the same run time as the 2S? Also, about how long would it last, for those of you who have this battery. Thanks!
The mAh is different, so they do not have the same run time.
Also, the 3S is only supposed to be used for short speed runs on flat smooth surfaces.... so you will not use the full capacity.
My 2200mAh 2S batteries last about a half hour.
Whatever it is I just typed... could be wrong.
Thanks! Just bought a 2000mAh 2S from my LHS.
