For everyday road use, a standard 2S hardcase LiPo stick pack is typically the easiest fit. It offers consistent power delivery, stable handling, and better runtime control compared with basic NiMH packs, especially once driving sessions get longer. The stock electronics are designed for 2S LiPo compatibility. If you are switching from the included NiMH setup, double-check LiPo cutoff settings and always confirm connector type before plugging in. Most Sport 3 / RS4 builds use a T-Plug (Deans) style battery connector. If your LiPo uses another connector, plan for an adapter lead or re-terminate the plug to match your setup.
