Side Battery Tray - Losi NASCAR 1/12 Scale

"LOW, LEFT, and FAST!"

Whether you’re running tight ovals, chasing top speed, or stretching for long run times, the Side Battery Tray by RC Race Gear is one of the best performance upgrades you can add to your Losi NASCAR 1/12 Scale RC car.

For oval racing, it’s as low and left as you can get — delivering a huge handling advantage by shifting the battery’s weight where it matters most. The result: a car that turns harder, stays more stable mid-corner, and drives off smoother.

Now redesigned to fit either side, this version adds a larger aerodynamic underbelly and more flexibility for any setup. Use one tray for ovals, or mount two trays for speed runs or long-distance builds. 4s and 6s setups are now easy by running up to 3 batteries using the stock battery location. 

Key Features:

• 🏁 Oval Dominance: The ultimate low-cost performance mod — positions the battery as low and left as possible for maximum grip and balance.

• ⚡ Speed Run Ready: Add a second or third tray and wire in series (4S or 6S) for extreme voltage and higher top speeds (ensure ESC and motor are rated for higher voltage).

• 🔋 Endurance Builds: Run 2–3 batteries in parallel for extended run times and reduced voltage drop.

• 🔄 Dual-Side Compatibility: Mounts on either side for complete setup flexibility.

• 💨 Aerodynamic Design: Enlarged underbody smooths airflow and enhances stability at high speeds.

• 🔧 Quick Installation: Bolts on in seconds using the stock 2mm hex bolts and battery strap (strap not included).

• 👀 Stealthy Look: Fits cleanly under the body for a true Box Stock appearance.

• 🧩 Precision 3D Printed: Lightweight, durable, and track-tested.

If you’re serious about performance — whether it’s tight ovals, all-out speed runs, or long-haul endurance builds — the Side Battery Tray from RC Race Gear is the upgrade that delivers.

Race Smarter. Race Harder.
