Thanks a lot for sharing your knowledge Scott! My new truck runs on a Li-Po.. when I was purchasing it I had a hard time justifying the price difference... but the salesman talked me into it. However, I'm glad I did it! The R/C truck has a significantly noticeable improvement in battery life. Now, all we need is a confirmation the new EVO uses this technology. This, in addition to the larger capacity battery in general on the EVO (vs the One X), should be a WIN! Thx again, Scott.
