For club nights and garage builds, the Tamiya 55117 Powerchamp RS AA alkaline battery supplies steady current and lasting runtime tailored to Mini 4WD needs. These cells help reduce mid-run voltage sag so your car behaves predictably on the course.
They are a sensible choice for hobbyists who want consistency without frequent battery changes. Use them for practice sessions or local events where stable performance matters more than extreme power tuning.
