Norman, The short answer would be no. It's not too high of a draw for some lithium cells. The longer version is... how do you know 4-5 amp draw? Lithium cells have a different voltage and much different internal resistance than NiMH or NiCad. If you would like i can run some number thru Motocalc for you to get a better idea of power draw and runtime. Shoot me an emial to snipped-for-privacy@aol.com and we'll talk.

I would like to use a lithium battery to power two GWS EDF-50 ducted fans.
