I have read it cover to cover carefully.

Victron does a Peukert calculation. The one he recommends does not. My personal favorite would be a smartgauge, which is better than either of the above if the information presented is correct. I don't use an amp-hour counter. Now that I live in the AGM world I probably should acquire one.

Have you bothered to read Ralph Hiesey's reasons on why he dosen't use the Perkert calculation or the use of temp compensation? Also take a look at the price difference in the smart guage and the trimetric. How accurate do you wish to be? And at what cost? Just some food for thought.
