The Serpent 411429 - F110 SF4 brass battery holder is a focused upgrade for the F110 SF4 Formula EP chassis that locks the battery in place and shifts weight where it counts. Brass offers dense, stable mass that enhances corner stability without complex setup changes.
Because brass is dense, placing it near the battery bay increases inertia in a controlled way. That added mass helps smooth mid corner direction changes and improves traction on exit when applied sensibly.
Made for the F110 SF4 chassis footprint, the holder mounts cleanly and holds the pack firmly under high loads. Fitment is straightforward and it works with standard pack sizes used in Formula EP racing.
