Note: Vmax can be limited by the module supply and/or capacitor voltage. Same applies for
the Vmin which is mostly limited by VBATT min.
Module energy usage:
Vavg = Vmax + Vmin / 2
Aavg = See typical values in Section 3.4.1
E[W] = Vavg * Aavg * Efficiency
Example:
Power Circuit Efficiency factor, e.g = 0.8
E[W] = ((4.5V + 3.0V) / 2) * 0.2A * 0.8 = 0.6375W (assuming the Cat NB1/2 worst case)
Discharge time:
T[s] = E[J] / E[W]
Example:
T[s] = 0.0098J / 0.6375W = 0.015s
