Well, I don't care if it has 5 minutes of run time at this point. Still looking for more batteries. I plan to use a Texas Instruments MSP430 for the battery monitor as we don't want to undervolt the batteries to a unsafe level (>3.2 volts.) At this point I am building a lithium ion battery charger for three 18650's in series.

To be able to run this motor on 3 of these 11.2-12.3v batteries which is roughly 1/3 of the rated 95 volts, how much current draw will I have?

Half finished prototype of the charger circuit: Can you see what is missing? besides solder and skill of course.
