You just wrote in a paragraph what I did in one sentence. Mah, Milli amp Hour, is Ma, Milli amps, with a unit of time, hours. The only way we measure load is with a unit of time. With out the unit of time you wouldn't know what size battery to run. So when I said 650mah draw I thought everyone new we were talking about how long it would last on any given battery pack. Sorry if I skipped a step. Next time I'll get out my graphing calculator and make you a picture. W.T.F!!!!!!!!!!
