Designed with upgrade-minded builders in mind, the GPM TB4126 provides a rigid, well located battery mount for the Tamiya TB04 chassis. Machined aluminium construction improves mounting stability and reduces pack shift during high load maneuvers, helping to preserve electrical contact and chassis balance. Suited to tuners and racers seeking a durable, serviceable battery solution, this holder integrates cleanly into the TB04 layout without altering fitment points.
