This black aluminum battery holder is a scale RC accessory designed for Tamiya Hotshot and Super Hotshot chassis, produced as model JR-THS10-BK by JAZRIDER. It replaces the factory tray to give a firmer, more stable battery attachment for hobby and competition use.
Install notes and fitment: the holder is built to align with the Hotshot battery location and fastens to the chassis using the existing mounting points. Installation typically needs basic hand tools such as a hex driver and original or matching screws; check screw lengths and thread types before final assembly. The component is supplied as a single replacement accessory and intended for RC-scale models only.
Tuning role: upgrading from a plastic tray to an aluminum holder reduces battery movement during dynamic events, improving repeatability when refining balance and chassis setup.
