EMW EV Dashboard

I had previously installed a sender board for the EMW EV Dashboard Android app:

Today, I hooked up the BlueTooth module and got it calibrated and running to my taste.  Here is a screen shot:

It shows current (both analog and digital), voltage (both analog and digital), charge (both analog and amp-hours remaining), and power being consumed.  I drove about 5 miles around the section block - the app worked really well.  And it looks like my estimate of roughly 50 miles range is going to be accurate - I consumed about 7 Ah for the 5 mile range.  70% DOD from 100 Ah is 70 Ah - and 70 Ah * 5 Mi / 7 Ah = 50 miles.  To one significant digit.
