This aluminium battery holder is an aftermarket mounting part produced by GPM for the TAMIYA TB04 chassis and supplied as 1 pcs. It is an RC-scale accessory intended to replace or upgrade the stock battery retention on TB04-based cars, offering a metal mounting point that changes the feel of battery security compared with the original plastic parts.
Compatibility is limited to the TB04 platform; verify fitment against your chassis layout before installation. The holder's role in setup is practical and focused: provide a firmer location for the pack, reduce unwanted movement during runs, and give a consistent reference when adjusting battery position for chassis balance and handling tuning. As with any aluminium upgrade, expect a difference in rigidity that can affect how the car responds to setup changes.
Installation notes: the part is designed to mount into the TB04 battery area using the existing mounting points on the chassis. Basic disassembly of the body and battery tray may be required, and careful alignment is recommended to maintain cable routing and connector clearance. No additional performance claims are implied beyond its function as a stiffer, metal replacement battery holder.
The part is sold as a single unit and intended for hobby use on the TB04 platform only, it is not for real vehicle use.
