7. Capacity Algorithm
The Blue Window keeps track of the battery capacity in the battery
bank by tracking the current in and out of the battery (integrating the
current over time). However, there are two corrections (current &
temperature) to the calculation to allow for a more accurate reading
over time. Because the Blue Window is keeping track of all current in
or out of the battery, it must powered at all times. When the Blue
Window first powers up, it sets the capacity to 50% so it will not read
correctly until after the first complete charge. Subsequent charges
must reach a voltage of 171 volts in order to reset the Blue Window
to fully charge. The source code for the Blue Window is licensed
