The XRAY 306198 battery holder for the T4'19 chassis is built to help drivers tune the car's balance with repeatable settings. Using graphite and an optional brass weight, the holder gives straightforward options for setup refinement.
The design supports shifting the battery forward, back and side to side, with a 4mm front/rear adjustment window. The brass piece supplies an extra 7.5g when fitted, useful for moving the centre of gravity toward the battery side.
Battery tape mounts only on top with this holder, so no under-chassis tape is needed. That keeps the chassis more flexible and can help lower ride height for enhanced grip and cornering precision.
For racers looking to micro-adjust balance and chassis behaviour, the XRAY 306198 offers easy, consistent changes that translate directly to handling differences on track.
