Hi FL. The Amps is the go-to number. 'Close to zero' needs more definition, depending on the batts and their behavior but maybe 1% to 2% of Amps compared with the batt capacity in Ah. (for Pb's).

So your 25.6A, even though you haven't described your batts, isn't there yet. And may actually be a looong way off 100%.

SOC is a calculated figure, and the BMV must be set up correctly to produce a useful figure. An onerous procedure it may seem, but until it's done, ignore the SOC.

That 'tail' % is actually one of the figures you'll need to supply it for it to sync correctly.
