How to Convert 6 Volt Power Wheels to 12 Volt

By William Kinsey ; Updated April 18, 2017

Power wheels are small motorized toy vehicles that are large enough for toddlers and small boys to drive. These toys usually use a 6-volt battery for power; however, the motor used in most of these toys is actually a 12 volt motor. It is possible to connect a second 6-volt battery in series with the original battery to elevate the the circuit to a 12-volt circuit. This increases the speed and power of the power wheel, but it also increases the stress and wear on the motor.

Open the back battery hatch to gain access to the battery compartment. Locate the two wires leaving the battery that run to the motor and motor control.

Cut the positive wire in half between the battery and the battery connector. Strip 1/2-inch of insulation off of both ends. Take the second battery and cut the battery connector off. Strip 1/2-inch of insulation off of both ends of wire.

Set the second battery in the batery compartment next to the original battery. Connect the positive wire from the original battery to the negative wire from the second battery. Connect the positive wire from the second battery back to the positive wire that connects to the battery connector. Place plastic twist caps on each splice.
