This battery post set is a vital component for securely mounting and retaining the battery pack within Kyosho's ZX7 and RB7 1/10 scale 2WD racing buggies. Constructed from durable, lightweight composite plastic, these posts are designed to withstand the rigors of competitive off-road racing while ensuring the battery remains firmly in place during aggressive maneuvers and landings. Their precision fit integrates seamlessly with the chassis's battery retention system, preventing unwanted movement that could affect weight distribution or disconnect power, thereby maintaining consistent performance and reliability on the track.
