[RE-wrenches] Mate 3s voltage off

[Mac Lewis]

Do you have a flexnet DC? I believe that is the master voltage indicator
that's displayed on the mate. There is an adjustment potentiometer for that
in the flexnet. Search for flexnet DC calibration and you will see a
document from outback for that.

This can make a huge difference for accurate soc calcs for lithium.
