Should be no problem at all. The motor will only draw what it needs, as long as you stay in its voltage range (~3-6volts). However, i use these batteries all the time. Do not expect to get 3000mah out of them. There are three kinds of liars: Liars, Damn'd Liars, and Battery Manufacturers! My charger says they only hold about 900mah down to the point when my LED flashlight cuts out.
Whats the current draw of your flashlight?
The capacity of a Li battery and indeed most other batteries is stated for a discharge rate of 1/20C .
At higher discharge rates , you will get less capacity.

Yes ... But ...
In support of @trum4n it is usually not possible for the user to prove (or disprove) the manufacturer's claimed capacity without damaging the battery.
