Relative Currents and Time

You might have noticed the use of relative currents (based on the battery's C current) and  time based on capacity.
This is different from other battery analysis systems.  The use of relative currents allow you to design BARs that work
independently of battery capacity.  If you prefer, you can still specify absolute values.

Figure 27: Action flow in a subroutine.

Figure 28: Here we have a relative load current of 1C.  If you ran this BAR on a 600mAh
battery you'd get a 600mA load, on a 2Ah battery you'd get a 2A load.
