True that the Baylite has some limitations...
The Baylite will tell you voltage and current on an instantaneous basis. It will also
track power used over time based on the measured current. So it will actually do a good job of telling what you have pulled out of the battery.
The big limitation is the Baylite only measures current in one direction not two directions as does the Trimetric. So as Scott is pointing out it will not tell you what goes back into your battery (unless you wire it up wrong...).
But for the price... I could install two Baylite's and track both the goes outta and the goes inna and still have a lot of beer money left over
Not to mention that the Trimetric is not going to win any aesthetic awards.
Knowing goes inna and goes outta does not quite
tell you charge state, unless your battery is 100% efficient at taking a charge but it does get you closer.
