Hi WrinklyWink, I mailed you as soon as I received your mail. You got a response within less than a day.
You should always download the latest file from The VESC-Project.com website.
In fact you can’t download old versions, no matter of the date of “purchase”.
The download will always be the latest VESC-Tool having the latest FW aboard.
There where plenty of updates last year!
Please update the VESC and see if the Voltage is still calculated funny/wrong.
I will also ask Benjamin about this issue.
