This replacement remote control receiver is specifically designed for HLX children's electric ride-on vehicles. The SX1718 520H-EPR unit operates on a 2.4G Bluetooth frequency and is compatible with V11, V13, V14, and V30 models. Please ensure that the control box appearance matches your original unit before purchasing. The remote requires two AAA batteries and a frequency-matching process upon initial use or after battery replacement to connect with the vehicle.
