There are two issues here. 1. Can the motors sustain more than 9 volts without damage? If I was TLC designing motors for use by kids, I'd make sure there was a large safety margin. New batteries are typically 0.1 - 0.2 volts above their nominal 1.5 (...) (23 years ago, 17-Jun-02, to lugnet.technic)
