Converting 6v power wheels to 12v

[Jeffey04]

I recently changed out the stock 6v battery that came with my childs car with a 12v battery. The car will run, and faster as i hoped, but it keeps shutting itself off after he drives it for a few minutes. It will turn itself back on though. Is this a connection problem or what?

It's probably a thermal cutout. You're lucky it has one.

Okay. So am i gonna have to replace the motor to? Or what can i do to keep the extra power and keep it from shutting off?

Either go back to a 6V battery or change the motor for one that is happy with 12V.

If the are any other electronics (how does it's throttle work?) Then this should also be reviewed and possibly replaced.

Reduce the voltage to 9v with power diodes and it will work.

how about just a 6V battery - with a higher Amp Rating.
while most toy car motors can operate on voltages around 5v - 12v. If you aren't sure that one is rated for 12v, you may eventually burn it out for the overvoltage.
