Determining the Conrail's Derived Run Time Using the 3S IMR 10440 Battery      Two timed-voltage tests were completed using the newly configured 3S pack.      Video showing the new timed-voltage test when using the 3S configuration is here. Test One 10 minutes - 3.970V 20 minutes - 3.834V 30 minutes - 3.719V Test Two 10 minutes - 3.964V 20 minutes - 3.831V 30 minutes - 3.711V      By "dropping" a battery (voltage) from the battery pack, the amp draw went down allowing an extra ten minutes of derived run time. It also put the maximim speed of 65 mph into a more efficient area of operation of the ESC circuit in the LocoFi™ decoder.      While the physical test proved correct, I'd also looked for other "proof" that the about 12V, supplied by three fully charged 3.7V nominal Lithium batteries was about right.
