We spent a few hours looking for a voltage regular to do just that without any success. We even looked into making our own voltage divider, but we simply could find resistors that could handle the wattage and be able dissipate the heat generated.

So we basically said... Ok. Well use it at 6.5 volts with an inline fuse.

6.5 volts is 90% of 7.2 volts so you'll get 90% of what you'd expect from that motor. It will be something like 140rpm instead of 160rpm.
