This aluminium battery holder is an aftermarket mounting part for the TAMIYA TB04 chassis and is supplied as a single unit. It replaces the original plastic retention and provides a metal mounting point to secure the battery pack with greater repeatability during setup adjustments.
Intended compatibility is the TB04 platform; confirm the holder aligns with your chassis battery bay and mounting points before installation. The unit is engineered to offer a stiffer battery location which can reduce pack movement and produce a consistent datum when altering battery position for handling changes.
Installation details: the holder installs into the TB04 battery area using the chassis' existing fastener locations. Partial disassembly of the body and battery tray may be required. Positioning should preserve connector clearance and cable routing to avoid interference. No additional performance claims are made beyond improved rigidity and fitment compared with the stock plastic part.
Supplied as a single piece for hobby RC use only; not for real vehicle applications.
