So let me see If I understand...If I run the 7.2V 2 amp motors with
the geckos will I fry them? or the best scenario is to run the
motors 20 times its nameplate voltage, in that case it will be
better to chosse the 3.6 so I can run them 20 times its voltage? the
question is that is it better to run the 3.6v 20 times its voltage
that running the 7.2v let say 10 times?
