The 17.5 guys you are driving with most likely have the boost, turbo, and timing cranked up on their esc. That and taller gearing could easily put them in 13.5 territory. You could always do the same if it's an issue for you. The 17.5 guys are most likely running a lot hotter than you are, which can shorten the lifespan of their electronics. A fresh battery is great but there is more to it than that.
