Kids Power Wheels Motor questions

I went to a local battery shop to buy a new battery for my son's
power wheels, and the guy talked me into buying a $15 lawn tractor
battery. It was great for about 3 hours, and then one of the motors in
the power wheels burnt up. The original battery was 12V, and I assume
the motor burnt up because of the larger current capability, or the
increased duty cycle (allowing him to go longer before a recharge and
cool down).

I wanted to know if I should try and place a current limiting circuit
in front of the motors to keep this from happening again, or possibly a
temperature shutdown on the motor? Any ideas?

Thanks,
Tom
