-	Charging lithium to <100% is easy; just lower charging voltage. Charging lithium to //some specific and consistent target// (30%, 50%, 80%, whatever) is notoriously difficult with solar as charging conditions are highly variable. This is not an issue if you are using 10A out of the 50A overnight; you will have plenty of safety net whether you charge to 40% or 90%. So play with lower charging voltages and with absorption times to see what keeps us in the sweet spot.	+	Charging lithium to <100% is easy; just lower charging voltage and see how the system behaves.
