Traxxas Battery Expansion Kit Rustler RC Accessory - 3725X

The Traxxas TRX3725X battery expansion kit is a fitment upgrade for the Traxxas Rustler that allows taller multi-cell battery packs to be installed in place of the standard single-cell configuration. If you want to run a higher-capacity LiPo or NiMH pack in your Rustler but the stock battery tray won't accommodate the increased height, this is the part that makes it possible. It's a targeted fix for a specific fitment issue rather than a performance part in itself — though running a larger battery pack can naturally extend your run time.
