  • Product typeCars
  • 24V operation powers compatible ride-on cars reliably

  • 40A relay handles high-current motors for stable performance
  • 7-pin conversion cable fits two different socket shapes

24 V Bluetooth Control Box Kit

This 24 V receiver kit replaces the original controller on compatible ride-on cars and robots. It pairs with the included 2.4 G Bluetooth transmitter for wireless operation.

7-pin socket with conversion cable

The board uses a 7-pin socket and ships with a conversion cable that fits two common socket shapes. A built-in 40 A relay handles high-current motors without an external slow-start module.

Replaces RX30, RX74-1, RX74-D or RX98 boards

The kit is a direct swap for those four model numbers when the original controller fails or when upgrading to a higher-power 24 V motor. It is not for vehicles that run on a different voltage or use a different pin layout.

Questions about this item

Will the 40 A relay overheat if my child drives the ride-on car continuously at full throttle?

The kit uses a 40 A relay rated for high-power 24 V motors, so sustained full-throttle runs stay within its current limit without thermal shutdown.

How loud is the control box and does it get hot during an all-day play session?

The solid-state receiver and relay produce no fan noise; only faint relay clicks are audible, and the aluminium heatsink keeps the unit warm but not hot to the touch after hours of use.

My ride-on has a 7-pin round plug — will the included conversion cable let me plug this kit straight in?

Yes, the kit ships with a 7-pin socket conversion cable that fits both common 7-pin shapes, so no extra adapters or soldering are needed.
