WOW! After horrible luck with some cheapo batteries from lhs and having great results with original battery in my slash 4x4 (and not being ready to make jump to lipo) I bought the 9.6 series 5 from Traxxas and used it for the first time today. I really need better tires now I could not be happier with the performance. I run dirt only and loose gravel just fun no racing and its out of control. I know its not the same as lipo but I am verry happy with it.
