Hello, I'm looking for Doc Wattson but with logging to PC.
Doc Wattson
http://www.rc-electronics-usa.com/ammeters/r102-amp-hour-specs.html
voltage 1% accuracy
current 2% accuracy
So far I found the:
http://www.victronenergy.com/battery-monitors/bmv-700
voltage 0.3% accuracy
current 0.4% accuracy
So it's clear winner ! yes it is expensive but it's industrial device.
However it works from 6.5V and does not have auxiliary power like Doc Wattson.
Any other I don't know about?
