This aluminium battery holder is an accessory designed specifically for the Tamiya MF01X chassis. It gives a 138mm mounting length matched to the MF01X battery envelope, providing a stiff anchor point that helps keep the pack stable while driving and during setup changes.
As an aluminium replacement for standard plastic trays, it reduces flex and offers more consistent battery placement. That repeatability can be useful when shifting pack position to alter balance and centre of gravity for better track performance.
Installation involves removing the original tray in the battery bay and securing this holder in the same location. No dedicated tooling is included; prepare suitable hex keys and hardware for your MF01X layout. This is an RC-only component and not for road vehicle use.
Use the holder to secure 138mm batteries on MF01X models when you need a firmer, repeatable mounting for setup sessions; it is supplied as an aftermarket upgrade by GPM.
