Like the title says......im using a 4s 5500mah 45C gensacearespammers Lipo and stock pinion in the truck. It concerns me on how warm the battery gets. I'm running on my front lawn (grass just cut). Doesn't seem to be any drivetrain binding. So I have to ask......is everyone who runs 4s Lipo experience this? If not then I may have to see if my LHS will allow me to return for a larger C rated Lipo.
